+## 🔴 Critical Bugs (Blocking Functionality)
+
+### BUG-005: CRF quality settings not showing when CRF mode is selected
+- **Status**: 🔴 OPEN
+- **Reporter**: User (2026-01-04 21:10)
+- **Module**: Convert
+- **Description**: When user selects "CRF (Constant Rate Factor)" as the Bitrate Mode, the Quality Preset dropdown does not appear. The UI remains empty where the quality settings should be.
+- **Steps to Reproduce**:
+  1. Open Convert module
+  2. Set Bitrate Mode to "CRF (Constant Rate Factor)"
+  3. Expected: Quality Preset dropdown appears
+  4. Actual: No quality controls show up
+- **Impact**: High - Cannot adjust quality in CRF mode, which is the default and most common mode
+- **Root Cause**: Likely over-corrected the visibility logic in `updateQualityVisibility()` function. Made rules too strict after fixing BUG-001 and BUG-002.
+- **Investigation Notes**:
+  - CBR mode is set by default (works correctly - hides quality controls)
+  - Previous fixes made `updateQualityVisibility()` check for: `hide || hideQuality || remux`
+  - Where `hideQuality = mode != "" && mode != "CRF"`
+  - Need to verify the logic flow when switching to CRF mode
+- **Files to Check**:
+  - `main.go:8851-8883` - `updateQualityVisibility()` function
+  - `main.go:8440-8532` - `updateEncodingControls()` function
+  - `main.go:7875-7888` - Bitrate mode selection callback
+- **Assigned To**: opencode (handoff from Claude)
+- **Verified**: No (not fixed yet)
+
+### BUG-006: Windows app crashes mid-conversion with no logs
+- **Status**: 🔴 OPEN
+- **Reporter**: User (2026-01-05)
+- **Module**: Convert / Queue / Logging (Windows)
+- **Description**: VT crashes during batch conversions (typically the 3rd or 4th job). FFmpeg continues running, but the app exits and no logs are created afterward.
+- **Steps to Reproduce**:
+  1. On Windows, queue multiple conversions in Convert module
+  2. Start queue
+  3. After several jobs, app crashes while FFmpeg keeps running
+  4. Expected: App stays alive, logs updated
+  5. Actual: App crashes, logs missing
+- **Impact**: High - data loss in UI state, no diagnostics
+- **Root Cause**: Unknown. Suspected background goroutine / UI thread issue or log path failure on Windows.
+- **Investigation Notes**:
+  - Need to confirm whether `%APPDATA%\VideoTools\logs\videotools.log` is created at all
+  - Crash likely happens before log writes or after log file handle is lost
+- **Files to Check**:
+  - `internal/logging/logging.go` (init + panic handling)
+  - `main.go` (conversion execution, queue updates)
+  - Windows build path for `getLogsDir()`
+- **Assigned To**: Unassigned
+- **Verified**: No

+## 🟠 High Priority Bugs (Major Issues)
+
+### BUG-010: Upscale jobs show no progress during FFmpeg conversions
+- **Status**: ✅ FIXED (2026-01-06, needs verification)
+- **Reporter**: Jake (2026-01-06)
+- **Module**: Upscale / Queue
+- **Description**: Upscale jobs that rely on FFmpeg conversions stay at 0.0% progress even while running; status updates do not advance until completion.
+- **Steps to Reproduce**:
+  1. Run Upscale job that uses FFmpeg conversion
+  2. Observe queue progress
+  3. Expected: Progress updates during conversion
+  4. Actual: Progress remains 0.0% until completion
+- **Impact**: High - No feedback during long-running jobs
+- **Root Cause**: FFmpeg progress parsing relied on stderr time updates; piped output used CR-only updates.
+- **Files to Check**:
+  - `main.go:executeUpscaleJob` (progress pipe parsing)
+- **Fixed By**: Codex
+- **Verified**: No

+
+### FEAT-003: Enhancement module blur control
+- **Status**: 🧭 IN PROGRESS
+- **Reporter**: Jake (2026-01-06)
+- **Module**: Enhancement
+- **Description**: Enhancement panel should include a blur control in addition to sharpen/denoise.
+- **Impact**: Medium - expected control in enhancement workflow
+- **Notes**: Implemented blur controls in Upscale first; Enhancement UI still pending.
+
+### FEAT-004: Upscale output quality should use Bitrate Mode controls
+- **Status**: 🧭 PLANNED
+- **Reporter**: Jake (2026-01-06)
+- **Module**: Upscale
+- **Description**: Replace Upscale "Output Quality" with the Bitrate Mode controls used in Convert Advanced.
+- **Impact**: Medium - consistent workflow across modules
+- **Notes**: Reuse Convert bitrate UI pattern once state manager is stable.

+
+## ✅ Recently Fixed (Last 7 Days)
+
+### BUG-001: Quality Preset showing in CBR/VBR modes (should only show in CRF)
+- **Status**: ✅ FIXED (2026-01-04)
+- **Reporter**: User
+- **Module**: Convert
+- **Description**: Quality Preset dropdown was showing when Bitrate Mode = CBR instead of only showing for CRF mode
+- **Impact**: Confusing UI, wrong controls visible
+- **Root Cause**: Duplicate visibility logic in `updateEncodingControls()` and `updateQualityVisibility()` conflicting with each other. Also `updateRemuxVisibility()` unconditionally showing containers.
+- **Fix**:
+  - Consolidated visibility logic into `updateQualityVisibility()` as single source of truth
+  - Made `updateRemuxVisibility()` call `updateEncodingControls()` instead of directly showing containers
+  - Removed explicit `.Hide()` call on quality section initialization
+  - Added `updateQualityVisibility()` call after section creation
+- **Files Changed**: `main.go:8522-8537, 8850, 8875, 8924-8928`
+- **Fixed By**: Claude
+- **Verified**: Yes, build passes
+
+### BUG-002: Target File Size showing when not in Target Size mode
+- **Status**: ✅ FIXED (2026-01-04)
+- **Reporter**: User
+- **Module**: Convert
+- **Description**: Target File Size container was visible even when Bitrate Mode was set to CRF
+- **Impact**: Confusing UI, irrelevant controls showing
+- **Root Cause**: `updateRemuxVisibility()` was unconditionally showing all encoding containers when not in remux mode
+- **Fix**: Changed `updateRemuxVisibility()` to call `updateEncodingControls()` which properly shows/hides based on bitrate mode
+- **Files Changed**: `main.go:8924-8928`
+- **Fixed By**: Claude
+- **Verified**: Yes, build passes
+
+### BUG-003: AAC and OPUS audio codec colors too similar
+- **Status**: ✅ FIXED (2026-01-04)
+- **Reporter**: User
+- **Module**: Convert (Audio codec selection)
+- **Description**: AAC (#7C3AED purple-blue) and OPUS (#8B5CF6 violet) colors were too similar to distinguish easily
+- **Impact**: Usability issue - hard to tell which codec is selected
+- **Fix**: Changed AAC color from #7C3AED (purple-blue) to #06B6D4 (bright cyan) for much better contrast
+- **Files Changed**: `internal/ui/colors.go:47`
+- **Fixed By**: Claude
+- **Verified**: Yes, build passes
+
+### BUG-004: Audio module missing drag & drop support
+- **Status**: ✅ FIXED (2026-01-04)
+- **Reporter**: User
+- **Module**: Audio
+- **Description**: Could not drag and drop audio or video files onto the Audio module tile
+- **Impact**: Forced manual file selection via browse button
+- **Fix**:
+  - Added `isAudioFile()` helper function to detect audio file extensions
+  - Modified `handleModuleDrop()` to accept audio files when dropping on audio module
+  - Added audio module handler in `handleModuleDrop()` to load files and show audio view
+- **Files Changed**: `main.go:2978, 3158-3180, 3186-3195`
+- **Fixed By**: Claude
+- **Verified**: Yes, build passes
+
+### BUG-007: Copy Error button lacked actionable details
+- **Status**: ✅ FIXED (2026-01-05)
+- **Reporter**: User
+- **Module**: Queue UI

+- **Files Changed**: `main.go`
+- **Fixed By**: Codex
+- **Verified**: Yes, build passes
+
+### BUG-008: About page "Logs Folder" not opening on Windows
+- **Status**: ✅ FIXED (2026-01-05)
+- **Reporter**: User
+- **Module**: About / OS integration
+- **Description**: Clicking Logs Folder did nothing on Windows
+- **Fix**: Use `explorer` with normalized path, ensure folder exists
+- **Files Changed**: `main.go`
+- **Fixed By**: Codex
+- **Verified**: Yes, build passes
+
+### BUG-009: Contact sheet output saved inside thumbnails folder
+- **Status**: ✅ FIXED (2026-01-05)

+# Convert Panel Modularization Plan (Dev24/25)
+
+## 🎯 Goal
+Move Advanced Convert UI logic out of main.go into modular UI components, keeping main.go as glue only.
+
+## 📁 File Structure
+
+```
+internal/ui/
+├── convert_advanced.go     # Advanced panel UI builder
+├── convert_state.go         # State manager + callbacks  
+├── convert_simple.go        # Simple panel UI builder (future)
+└── convert_types.go          # Shared types and constants
+
+main.go (cleanup)
+├── Keep encoding/FFmpeg logic in existing helpers
+├── Import internal/ui package only
+└── Replace UI blocks with module calls
+```
+
+## 🔧 What to Extract from main.go
+
+### 1. UI Builders (buildConvertView -> convert_advanced.go)
+- Advanced panel dropdowns, sliders, toggles
+- Layout containers and responsive sizing
+- Quality presets and format selection
+- Hardware acceleration controls
+- Two-pass encoding interface
+- Progress preview and command display
+
+### 2. State Management (convertUIState -> convert_state.go)
+```go
+type ConvertState struct {
+    // Current settings
+    Format         formatOption
+    Quality        string
+    Preset         string
+    TwoPass        bool
+    HardwareAccel  bool
+    
+    // UI bindings
+    FormatList     *widget.Select
+    QualitySelect  *widget.Select
+    // ... etc
+}
+
+type ConvertUIBindings struct {
+    // Controls accessible to main.go
+    StartConversion  func()
+    StopConversion   func()
+    ShowPreview     func()
+    // ... etc
+}
+```
+
+### 3. Callback Functions (applyQuality, setQuality, updateEncodingControls -> convert_state.go)
+- State change management
+- Validation and sanitization
+- Settings persistence
+- Progress update handling
+
+## 🔄 Integration Pattern
+
+### main.go Changes:
+```go
+import "git.leaktechnologies.dev/stu/VideoTools/internal/ui"
+
+// Replace giant UI block with:
+if useAdvanced {
+    panel := ui.BuildConvertAdvancedPanel(state, src)
+    mainContent := container.NewVBox(panel)
+} else {
+    panel := ui.BuildConvertSimplePanel(state, src)  
+    mainContent := container.NewVBox(panel)
+}
+```
+
+### Module Interface:
+```go
+func BuildConvertAdvancedPanel(state *appState, src *videoSource) (fyne.CanvasObject, *ConvertUIBindings)
+func BuildConvertSimplePanel(state *appState, src *videoSource) (fyne.CanvasObject, *ConvertUIBindings)
+func InitConvertState(state *appState, src *videoSource) *ConvertState
+```
+
+## 🎨 Benefits
+
+1. **Maintainable**: UI logic separated from core logic
+2. **Testable**: UI components can be unit tested independently
+3. **Reusability**: Simple/Advanced panels reused in other modules
+4. **Clean Code**: main.go becomes readable and focused
+5. **Future-Proof**: Easy to add new UI features without bloating main.go
+
+## 📋 Implementation Order
+
+1. **Phase 1**: Create convert_types.go with shared types
+2. **Phase 2**: Extract state management into convert_state.go
+3. **Phase 3**: Build convert_advanced.go with UI logic
+4. **Phase 4**: Update main.go to use new modules
+5. **Phase 5**: Test and iterate on modular interface
+
+## 🎯 Success Metrics
+
+✅ main.go reduced by 2000+ lines  
+✅ UI logic properly separated and testable  
+✅ Clean module boundaries with no circular deps  
+✅ Maintain existing functionality and user experience  
+✅ Foundation for future UI improvements in other modules  
+
+This modularization will make the codebase much more maintainable and prepare us for advanced features in dev25.

 # VideoTools - Completed Features
 
+## Version 0.1.0-dev24 (2026-01-06) - DVD Menu Templating System
+
+### Features
+- ✅ **DVD Menu Templating System**
+  - Refactored `author_menu.go` to support multiple, selectable menu templates.
+  - Implemented a `MenuTemplate` interface for easy extensibility.
+  - Created three initial menu templates:
+    - **Simple**: The default, clean menu style.
+    - **Dark**: A dark-themed menu for a more cinematic feel.
+    - **Poster**: A template that uses a user-provided image as the background.
+- ✅ **Menu Customization UI**
+  - Added a "Menu Template" dropdown to the authoring settings tab.
+  - Added a "Select Background Image" button that appears when the "Poster" template is selected.
+  - User's menu template and background image choices are persisted in the configuration.
+
+## Version 0.1.0-dev23 (2026-01-04) - UI Cleanup & About Dialog
+
+
+### UI/UX
+- ✅ **Colored select polish** - one-click dropdown, left accent bar, softer blue-grey background, rounded corners, larger text
+- ✅ **Panel input styling** - input and panel backgrounds aligned to dropdown tone
+- ✅ **Convert panel buttons** - Auto-crop and interlace actions styled to match settings panel
+- ✅ **About / Support redesign** - mockup-aligned layout, VT + LT logos, Logs Folder placement, support placeholder
+
+### Stability
+- ✅ **Audio module crash fix** - prevent nil entry panic on initial quality selection
+
+## Version 0.1.0-dev22 (2026-01-01) - Bug Fixes & Documentation
+
+### Bug Fixes
+- ✅ **Refactored Command Execution (Windows Console Fix Extended to Core Modules)**
+  - Extended the refactoring of command execution to `audio_module.go`, `author_module.go`, and `platform.go`.
+  - All direct calls to `exec.Command` and `exec.CommandContext` in these modules now use `utils.CreateCommand` and `utils.CreateCommandRaw`.
+  - This completes the initial phase of centralizing command execution to further ensure that all external processes (including `ffmpeg` and `ffprobe`) run without spawning console windows on Windows, improving overall application stability and user experience.
+
+- ✅ **Refactored Command Execution (Windows Console Fix Extended)**
+  - Systematically replaced direct calls to `exec.Command` and `exec.CommandContext` across `main.go` and `internal/benchmark/benchmark.go` with `utils.CreateCommand` and `utils.CreateCommandRaw`.
+  - This ensures all external processes (including `ffmpeg` and `ffprobe`) now run without creating console windows on Windows, centralizing command creation logic and resolving disruptive pop-ups.
+
+- ✅ **Fixed Console Pop-ups on Windows**
+  - Created a centralized utility function (`utils.CreateCommand`) that starts external processes without creating a console window on Windows.
+  - Refactored the benchmark module and main application logic to use this new utility.
+  - This resolves the issue where running benchmarks or other operations would cause disruptive `ffmpeg.exe` console windows to appear.
+
+### Documentation
+- ✅ **Addressed Platform Gaps (Windows Guide)**
+  - Created a new, comprehensive installation guide for native Windows (`docs/INSTALL_WINDOWS.md`).
+  - Refactored the main `INSTALLATION.md` into a platform-agnostic hub that now links to the separate, detailed guides for Windows and Linux/macOS.
+  - This provides a clear, user-friendly path for users on all major platforms.
+
+- ✅ **Aligned Documentation with Reality**
+  - Audited and tagged all planned features in the documentation with `[PLANNED]`.
+  - This provides a more honest representation of the project's capabilities.
+  - Removed broken links from the documentation index.
+
+- ✅ **Created Project Status Page**
+  - Created `PROJECT_STATUS.md` to provide a single source of truth for project status.
+  - Summarizes implemented, planned, and in-progress features.
+  - Highlights critical known issues, like the player module bugs.
+  - Linked from the main `README.md` to ensure users and developers have a clear, honest overview of the project's state.
+
 This file tracks completed features, fixes, and milestones.
 
-## Version 0.1.0-dev19 (2025-12-18 to 2025-12-20) - Convert Module Cleanup & UX Polish
+## Version 0.1.0-dev20+ (2025-12-28) - Queue UI Performance & Workflow Improvements
+
+### Bug Fixes
+- ✅ **Player Module Investigation**
+  - Investigated reported player crash
+  - Discovered player is ALREADY fully internal and lightweight
+  - Uses FFmpeg directly (no external VLC/MPV/FFplay dependencies)
+  - Implementation: FFmpeg pipes raw frames + audio → Oto library for output
+  - Frame-accurate seeking and A/V sync built-in
+  - Error handling: Falls back to video-only playback if audio fails
+  - Player module re-enabled - follows VideoTools' core principles
+
+### Workflow Enhancements
+- ✅ **Benchmark Result Caching**
+  - Benchmark results now persist across app restarts
+  - Opening Benchmark module shows cached results instead of auto-running
+  - Clear timestamp display (e.g., "Showing cached results from December 28, 2025 at 2:45 PM")
+  - "Run New Benchmark" button available when viewing cached results
+  - Auto-runs only when no previous results exist or hardware has changed (GPU detection)
+  - Saves to `~/.config/VideoTools/benchmark.json` with last 10 runs in history
+  - No more redundant benchmarks every time you open the module
+
+- ✅ **Merge Module Output Path UX Improvement**
+  - Split single output path field into separate folder and filename fields
+  - "Output Folder" field with "Browse Folder" button for directory selection
+  - "Output Filename" field for easy filename editing (e.g., "merged.mkv")
+  - No more navigating through long paths to change filenames
+  - Cleaner, more intuitive interface following standard file dialog patterns
+  - Auto-population sets directory and filename independently
+
+- ✅ **Queue Priority System for Convert Now**
+  - "Convert Now" during active conversions adds job to top of queue (after running job)
+  - "Add to Queue" continues to add to end as expected
+  - Implemented AddNext() method in queue package for priority insertion
+  - User feedback message indicates queue position: "Added to top of queue!" vs "Conversion started!"
+  - Better workflow when adding files during active batch conversions
+
+- ✅ **Auto-Cleanup for Failed Conversions**
+  - Convert jobs now automatically delete incomplete/broken output files on failure
+  - Success tracking ensures complete files are never removed
+  - Prevents accumulation of partial files from crashed/cancelled conversions
+  - Cleaner disk space management and error handling
+
+- ✅ **Queue List Jankiness Reduction**
+  - Increased auto-refresh interval from 1000ms to 2000ms for smoother updates
+  - Reduced scroll restoration delay from 50ms to 10ms for faster position recovery
+  - Fixed race condition in scroll offset saving
+  - Eliminated visible jumping during queue view rebuilds
+
+### Performance Optimizations
+- ✅ **Queue View Button Responsiveness**
+  - Fixed Windows-specific button lag after conversion completion
+  - Eliminated redundant UI refreshes in queue button handlers (Pause, Resume, Cancel, Remove, Move Up/Down, etc.)
+  - Queue onChange callback now handles all refreshes automatically - removed duplicate manual calls
+  - Added stopQueueAutoRefresh() before navigation to prevent conflicting UI updates
+  - Result: Instant button response on Windows (was 1-3 second lag)
+  - Reported by: Jake & Stu
+
+- ✅ **Main Menu Performance**
+  - Fixed main menu lag when sidebar visible and queue active
+  - Implemented 300ms throttling for main menu rebuilds (prevents excessive redraws)
+  - Cached jobQueue.List() calls to eliminate multiple expensive copies (was 2-3 copies per refresh)
+  - Smart conditional refresh: only rebuild sidebar when history actually changes
+  - Result: 3-5x improvement in main menu responsiveness, especially on Windows
+  - RAM usage confirmed: 220MB (lean and efficient for video processing app)
+
+- ✅ **Queue Auto-Refresh Optimization**
+  - Reduced auto-refresh interval from 500ms to 1000ms (1 second)
+  - Reduces UI thread pressure on Windows while maintaining smooth progress updates
+  - Combined with 500ms manual throttle in refreshQueueView() for optimal balance
+
+### User Experience Improvements
+- ✅ **Benchmark UI Cleanup**
+  - Hide benchmark indicator in Convert module when settings are already applied
+  - Only show "Benchmark: Not Applied" status when action is needed
+  - Removes clutter from UI when using benchmark settings
+  - Cleaner interface for active conversions with benchmark recommendations
+
+- ✅ **Queue Position Labeling**
+  - Fixed confusing priority display in queue view
+  - Changed from internal priority numbers (3, 2, 1) to user-friendly queue positions (1, 2, 3)
+  - Now displays "Queue Position: 1" for first job, "Queue Position: 2" for second, etc.
+  - Applied to both Pending and Paused jobs
+  - Much clearer for users to understand execution order
+
+### Remux Safety System (Fool-Proof Implementation)
+- ✅ **Comprehensive Codec Compatibility Validation**
+  - Added validateRemuxCompatibility() function with format-specific checks
+  - Automatically detects incompatible codec/container combinations
+  - Validates before ANY remux operation to prevent silent failures
+
+- ✅ **Container-Specific Validation**
+  - MP4: Blocks VP8, VP9, AV1, Theora, Vorbis, Opus (not reliably supported)
+  - MKV: Allows almost everything (ultra-flexible)
+  - WebM: Enforces VP8/VP9/AV1 video + Vorbis/Opus audio only
+  - MOV: Apple-friendly codecs (H.264, H.265, ProRes, MJPEG)
+
+- ✅ **Automatic Fallback to Re-encoding**
+  - WMV/ASF sources automatically re-encode (timestamp/codec issues)
+  - FLV with legacy codecs (Sorenson/VP6) auto re-encode
+  - Incompatible codec/container pairs auto re-encode to safe default (H.264)
+  - User never gets broken files - system handles it transparently
+
+- ✅ **Auto-Fixable Format Detection**
+  - AVI: Applies -fflags +genpts for timestamp regeneration
+  - FLV (H.264): Applies timestamp fixes
+  - MPEG-TS/M2TS/MTS: Extended analysis + timestamp fixes
+  - VOB (DVD rips): Full timestamp regeneration
+  - All apply -avoid_negative_ts make_zero automatically
+
+- ✅ **Enhanced FFmpeg Safety Flags**
+  - All remux operations now include:

+# Player Module Performance Issues & Fixes
+
+## Current Problems Causing Stuttering
+
+### 1. **Separate Video & Audio Processes (No Sync)**
+**Location:** `main.go:9144` (runVideo) and `main.go:9233` (runAudio)
+
+**Problem:**
+- Video and audio run in completely separate FFmpeg processes
+- No synchronization mechanism between them
+- They will inevitably drift apart, causing A/V desync and stuttering
+
+**Current Implementation:**
+```go
+func (p *playSession) startLocked(offset float64) {
+    p.runVideo(offset)  // Separate process
+    p.runAudio(offset)  // Separate process
+}
+```
+
+**Why It Stutters:**
+- If video frame processing takes too long → audio continues → desync
+- If audio buffer underruns → video continues → desync
+- No feedback loop to keep them in sync
+
+---
+
+### 2. **Audio Buffer Too Small**
+**Location:** `main.go:8960` (audio context) and `main.go:9274` (chunk size)
+
+**Problem:**
+```go
+// Audio context with tiny buffer (42ms at 48kHz)
+audioCtxGlobal.ctx, audioCtxGlobal.err = oto.NewContext(sampleRate, channels, bytesPerSample, 2048)
+
+// Tiny read chunks (21ms of audio)
+chunk := make([]byte, 4096)
+```
+
+**Why It Stutters:**
+- 21ms chunks mean we need to read 47 times per second
+- Any delay > 21ms causes audio dropout/stuttering
+- 2048 sample buffer gives only 42ms protection against underruns
+- Modern systems need 100-200ms buffers for smooth playback
+
+---
+
+### 3. **Volume Processing in Hot Path**
+**Location:** `main.go:9294-9318`
+
+**Problem:**
+```go
+// Processes volume on EVERY audio chunk read
+for i := 0; i+1 < n; i += 2 {
+    sample := int16(binary.LittleEndian.Uint16(tmp[i:]))
+    amp := int(float64(sample) * gain)
+    // ... clamping ...
+    binary.LittleEndian.PutUint16(tmp[i:], uint16(int16(amp)))
+}
+```
+
+**Why It Stutters:**
+- CPU-intensive per-sample processing
+- Happens 47 times/second with tiny chunks
+- Blocks the audio read loop
+- Should use FFmpeg's volume filter or hardware mixing
+
+---
+
+### 4. **Video Frame Pacing Issues**
+**Location:** `main.go:9200-9203`
+
+**Problem:**
+```go
+if delay := time.Until(nextFrameAt); delay > 0 {
+    time.Sleep(delay)
+}
+nextFrameAt = nextFrameAt.Add(frameDur)
+```
+
+**Why It Stutters:**
+- `time.Sleep()` is not precise (can wake up late)
+- Cumulative drift: if one frame is late, all future frames shift
+- No correction mechanism if we fall behind
+- UI thread delays from `DoFromGoroutine` can cause frame drops
+
+---
+
+### 5. **UI Thread Blocking**
+**Location:** `main.go:9207-9215`
+
+**Problem:**
+```go
+// Every frame waits for UI thread to be available
+fyne.CurrentApp().Driver().DoFromGoroutine(func() {
+    p.img.Image = frame
+    p.img.Refresh()
+}, false)
+```
+
+**Why It Stutters:**
+- If UI thread is busy, frame updates queue up
+- Can cause video to appear choppy even if FFmpeg is delivering smoothly
+- No frame dropping mechanism if UI can't keep up
+
+---
+
+### 6. **Frame Allocation on Every Frame**
+**Location:** `main.go:9205-9206`
+
+**Problem:**
+```go
+// Allocates new frame buffer 24-60 times per second
+frame := image.NewRGBA(image.Rect(0, 0, p.targetW, p.targetH))
+utils.CopyRGBToRGBA(frame.Pix, buf)
+```
+
+**Why It Stutters:**
+- Memory allocation on every frame causes GC pressure
+- Extra copy operation adds latency
+- Could reuse buffers or use ring buffer
+
+---
+
+## Recommended Fixes (Priority Order)
+
+### Priority 1: Increase Audio Buffers (Quick Fix)
+
+**Change `main.go:8960`:**
+```go
+// OLD: 2048 samples = 42ms
+audioCtxGlobal.ctx, audioCtxGlobal.err = oto.NewContext(sampleRate, channels, bytesPerSample, 2048)
+
+// NEW: 8192 samples = 170ms (more buffer = smoother playback)
+audioCtxGlobal.ctx, audioCtxGlobal.err = oto.NewContext(sampleRate, channels, bytesPerSample, 8192)
+```
+
+**Change `main.go:9274`:**
+```go
+// OLD: 4096 bytes = 21ms
+chunk := make([]byte, 4096)
+
+// NEW: 16384 bytes = 85ms per chunk
+chunk := make([]byte, 16384)
+```
+
+**Expected Result:** Audio stuttering should improve significantly
+
+---
+
+### Priority 2: Use FFmpeg for Volume Control
+
+**Change `main.go:9238-9247`:**
+```go
+// Add volume filter to FFmpeg command instead of processing in Go
+volumeFilter := ""
+if p.muted || p.volume <= 0 {
+    volumeFilter = "-af volume=0"
+} else if math.Abs(p.volume - 100) > 0.1 {
+    volumeFilter = fmt.Sprintf("-af volume=%.2f", p.volume/100.0)
+}
+
+cmd := exec.Command(platformConfig.FFmpegPath,
+    "-hide_banner", "-loglevel", "error",
+    "-ss", fmt.Sprintf("%.3f", offset),
+    "-i", p.path,
+    "-vn",
+    "-ac", fmt.Sprintf("%d", channels),
+    "-ar", fmt.Sprintf("%d", sampleRate),
+    volumeFilter,  // Let FFmpeg handle volume
+    "-f", "s16le",
+    "-",
+)
+```
+
+**Remove volume processing loop (lines 9294-9318):**
+```go
+// Simply write chunks directly
+localPlayer.Write(chunk[:n])
+```
+
+**Expected Result:** Reduced CPU usage, smoother audio
+
+---
+
+### Priority 3: Use Single FFmpeg Process with A/V Sync
+
+**Conceptual Change:**
+Instead of separate video/audio processes, use ONE FFmpeg process that:
+1. Outputs video frames to one pipe
+2. Outputs audio to another pipe (or use `-f matroska` with demuxing)
+3. Maintains sync internally
+
+**Pseudocode:**
+```go
+cmd := exec.Command(platformConfig.FFmpegPath,
+    "-ss", fmt.Sprintf("%.3f", offset),
+    "-i", p.path,
+    // Video stream
+    "-map", "0:v:0",
+    "-f", "rawvideo",
+    "-pix_fmt", "rgb24",
+    "-r", fmt.Sprintf("%.3f", p.fps),
+    "pipe:4",  // Video to fd 4
+    // Audio stream
+    "-map", "0:a:0",
+    "-ac", "2",
+    "-ar", "48000",
+    "-f", "s16le",
+    "pipe:5",  // Audio to fd 5
+)
+```
+
+**Expected Result:** Perfect A/V sync, no drift
+
+---
+
+### Priority 4: Frame Buffer Reuse
+
+**Change `main.go:9205-9206`:**
+```go
+// Reuse frame buffers instead of allocating every frame
+type framePool struct {
+    pool sync.Pool
+}
+
+func (p *framePool) get(w, h int) *image.RGBA {
+    if img := p.pool.Get(); img != nil {
+        return img.(*image.RGBA)
+    }
+    return image.NewRGBA(image.Rect(0, 0, w, h))
+}
+
+func (p *framePool) put(img *image.RGBA) {
+    // Clear pixel data
+    for i := range img.Pix {
+        img.Pix[i] = 0
+    }
+    p.pool.Put(img)
+}
+
+// In video loop:
+frame := framePool.get(p.targetW, p.targetH)
+utils.CopyRGBToRGBA(frame.Pix, buf)
+// ... use frame ...
+// Note: can't return to pool if UI is still using it
+```
+
+**Expected Result:** Reduced GC pressure, smoother frame delivery
+
+---
+
+### Priority 5: Adaptive Frame Timing
+
+**Change `main.go:9200-9203`:**
+```go
+// Track actual vs expected time to detect drift
+now := time.Now()
+behind := now.Sub(nextFrameAt)
+
+if behind < 0 {
+    // We're ahead, sleep until next frame
+    time.Sleep(-behind)
+} else if behind > frameDur*2 {
+    // We're way behind (>2 frames), skip this frame
+    logging.Debug(logging.CatFFMPEG, "dropping frame, %.0fms behind", behind.Seconds()*1000)
+    nextFrameAt = now
+    continue
+} else {
+    // We're slightly behind, catchup gradually
+    nextFrameAt = now.Add(frameDur / 2)
+}
+
+nextFrameAt = nextFrameAt.Add(frameDur)
+```
+
+**Expected Result:** Better handling of temporary slowdowns, adaptive recovery
+
+---
+
+## Testing Checklist
+
+After each fix, test:
+
+- [ ] 24fps video plays smoothly
+- [ ] 30fps video plays smoothly
+- [ ] 60fps video plays smoothly
+- [ ] Audio doesn't stutter
+- [ ] A/V sync maintained over 30+ seconds
+- [ ] Seeking doesn't cause prolonged stuttering
+- [ ] CPU usage is reasonable (<20% for playback)
+- [ ] Works on both Linux and Windows
+- [ ] Works with various codecs (H.264, H.265, VP9)
+- [ ] Volume control works smoothly
+- [ ] Pause/resume doesn't cause issues
+
+---
+
+## Performance Monitoring
+
+Add instrumentation to measure:
+
+```go
+// Video frame timing
+frameDeliveryTime := time.Since(frameReadStart)
+if frameDeliveryTime > frameDur*1.5 {
+    logging.Debug(logging.CatFFMPEG, "slow frame delivery: %.1fms (target: %.1fms)",
+        frameDeliveryTime.Seconds()*1000,
+        frameDur.Seconds()*1000)
+}
+
+// Audio buffer health
+if audioBufferFillLevel < 0.3 {
+    logging.Debug(logging.CatFFMPEG, "audio buffer low: %.0f%%", audioBufferFillLevel*100)
+}
+```
+
+---
+
+## Alternative: Use External Player Library
+
+If these tweaks don't achieve smooth playback, consider:
+
+1. **mpv library** (libmpv) - Industry standard, perfect A/V sync
+2. **FFmpeg's ffplay** code - Reference implementation
+3. **VLC libvlc** - Proven playback engine
+
+These handle all the complex synchronization automatically.
+
+---
+
+## Summary
+
+**Root Causes:**
+1. Separate video/audio processes with no sync
+2. Tiny audio buffers causing underruns
+3. CPU waste on per-sample volume processing
+4. Frame timing drift with no correction
+5. UI thread blocking frame updates
+
+**Quick Wins (30 min):**
+- Increase audio buffers (Priority 1)
+- Move volume to FFmpeg (Priority 2)
+
+**Proper Fix (2-4 hours):**

+# Windows Build Performance Guide
+
+## Issue: Slow Builds (5+ Minutes)
+
+If you're experiencing very slow build times on Windows, follow these steps to dramatically improve performance.
+
+## Quick Fixes
+
+### 1. Use the Optimized Build Scripts
+
+We've updated the build scripts with performance optimizations:
+
+```bash
+# Git Bash (Most Windows users)
+./scripts/build.sh
+
+# PowerShell
+.\scripts\build.ps1
+
+# Command Prompt
+.\scripts\build.bat
+```
+
+**New Optimizations:**
+- `-p N`: Parallel compilation using all CPU cores
+- `-trimpath`: Faster builds and smaller binaries
+- `-ldflags="-s -w"`: Strip debug symbols (faster linking)
+
+### 2. Add Windows Defender Exclusions (CRITICAL!)
+
+**This is the #1 cause of slow builds on Windows.**
+
+Windows Defender scans every intermediate `.o` file during compilation, adding 2-5 minutes to build time.
+
+#### Automated Script (Easiest - For Git Bash Users):
+
+**From Git Bash (Run as Administrator):**
+```bash
+# Run the automated exclusion script
+powershell.exe -ExecutionPolicy Bypass -File ./scripts/add-defender-exclusions.ps1
+```
+
+**To run Git Bash as Administrator:**
+1. Search for "Git Bash" in Start Menu
+2. Right-click → "Run as administrator"
+3. Navigate to your VideoTools directory
+4. Run the command above
+
+#### Manual Method (GUI):
+
+1. **Open Windows Security**
+   - Press `Win + I` → Update & Security → Windows Security → Virus & threat protection
+
+2. **Add Exclusions** (Manage settings → Add or remove exclusions):
+   - `C:\Users\YourName\go` - Go package cache
+   - `C:\Users\YourName\AppData\Local\go-build` - Go build cache
+   - `C:\Users\YourName\Projects\VideoTools` - Your project directory
+   - `C:\msys64` - MinGW toolchain (if using MSYS2)
+
+#### PowerShell Method (If Not Using Git Bash):
+
+Run PowerShell as Administrator:
+```powershell
+# Run the automated script
+.\scripts\add-defender-exclusions.ps1
+
+# Or add manually:
+Add-MpPreference -ExclusionPath "$env:LOCALAPPDATA\go-build"
+Add-MpPreference -ExclusionPath "$env:USERPROFILE\go"
+Add-MpPreference -ExclusionPath "C:\Users\$env:USERNAME\Projects\VideoTools"
+Add-MpPreference -ExclusionPath "C:\msys64"
+```
+
+**Expected improvement:** 5 minutes → 30-90 seconds
+
+### 3. Use Go Build Cache
+
+Make sure Go's build cache is enabled (it should be by default):
+
+```powershell
+# Check cache location
+go env GOCACHE
+
+# Should output something like: C:\Users\YourName\AppData\Local\go-build
+```
+
+**Don't use `-Clean` flag** unless you're troubleshooting. Clean builds are much slower.
+
+### 4. Optimize MinGW/GCC
+
+If using MSYS2/MinGW, ensure it's in your PATH before other compilers:
+
+```powershell
+# Check GCC version
+gcc --version
+
+# Should show: gcc (GCC) 13.x or newer
+```
+
+## Advanced Optimizations
+
+### 1. Use Faster SSD for Build Cache
+
+Move your Go cache to an SSD if it's on an HDD:
+
+```powershell
+# Set custom cache location on fast SSD
+$env:GOCACHE = "D:\FastSSD\go-build"
+go env -w GOCACHE="D:\FastSSD\go-build"
+```
+
+### 2. Increase Go Build Parallelism
+
+For high-core-count CPUs:
+
+```powershell
+# Use all CPU threads
+$env:GOMAXPROCS = [Environment]::ProcessorCount
+
+# Or set specific count
+$env:GOMAXPROCS = 16
+```
+
+### 3. Disable Real-Time Scanning Temporarily
+
+**Only during builds** (not recommended for normal use):
+
+```powershell
+# Disable (run as Administrator)
+Set-MpPreference -DisableRealtimeMonitoring $true
+
+# Build your project
+.\scripts\build.ps1
+
+# Re-enable immediately after
+Set-MpPreference -DisableRealtimeMonitoring $false
+```
+
+## Benchmarking Your Build
+
+Time your build to measure improvements:
+
+```powershell
+# PowerShell
+Measure-Command { .\scripts\build.ps1 }
+
+# Command Prompt
+echo %time% && .\scripts\build.bat && echo %time%
+```
+
+## Expected Build Times
+
+With optimizations:
+
+| Machine Type | Clean Build | Incremental Build |
+|--------------|-------------|-------------------|
+| Modern Desktop (8+ cores, SSD) | 30-60 seconds | 5-15 seconds |
+| Laptop (4-6 cores, SSD) | 60-90 seconds | 10-20 seconds |
+| Older Machine (2-4 cores, HDD) | 2-3 minutes | 30-60 seconds |
+
+**Without Defender exclusions:** Add 2-5 minutes to above times.
+
+## Still Slow?
+
+### Check for Common Issues:
+
+1. **Antivirus Software**
+   - Third-party antivirus can be even worse than Defender
+   - Add same exclusions in your antivirus settings
+
+2. **Disk Space**
+   - Go cache can grow large
+   - Ensure 5+ GB free space on cache drive
+
+3. **Background Processes**
+   - Close resource-heavy applications during builds
+   - Check Task Manager for CPU/disk usage
+
+4. **Network Drives**
+   - **Never** build on network drives or cloud-synced folders
+   - Move project to local SSD
+
+5. **WSL2 vs Native Windows**
+   - Building in WSL2 can be faster
+   - But adds complexity with GUI apps
+
+## Troubleshooting Commands
+
+```powershell
+# Check Go environment
+go env
+
+# Check build cache size
+Get-ChildItem -Path (go env GOCACHE) -Recurse | Measure-Object -Property Length -Sum
+
+# Clean cache if too large (>10 GB)
+go clean -cache
+
+# Verify GCC is working
+gcc --version
+```
+
+## Getting Help
+
+If you're still experiencing slow builds after following this guide:
+
+1. **Capture build timing:**
+   ```powershell
+   Measure-Command { go build -v -x . } > build-log.txt 2>&1
+   ```
+
+2. **Check system specs:**
+   ```powershell
+   systeminfo | findstr /C:"Processor" /C:"Physical Memory"
+   ```
+
+3. **Report issue** with:
+   - Build timing output
+   - System specifications
+   - Windows version
+   - Antivirus software in use
+
+## Summary: Quick Start for Git Bash Users
+
+**If you're using Git Bash on Windows (most users), do this:**
+
+1. **Open Git Bash as Administrator**
+   - Right-click Git Bash → "Run as administrator"
+
+2. **Navigate to VideoTools:**
+   ```bash
+   cd ~/Projects/VideoTools  # or wherever your project is
+   ```
+
+3. **Add Defender exclusions (ONE TIME ONLY):**
+   ```bash
+   powershell.exe -ExecutionPolicy Bypass -File ./scripts/add-defender-exclusions.ps1
+   ```
+
+4. **Close and reopen Git Bash (normal, not admin)**
+
+5. **Build with optimized script:**
+   ```bash
+   ./scripts/build.sh
+   ```
+
+**Expected result:** 5+ minutes → 30-90 seconds
+
+### What Each Step Does:
+1. ✅ **Add Windows Defender exclusions** (saves 2-5 minutes) - Most important!
+2. ✅ **Use optimized build scripts** (saves 30-60 seconds) - Parallel compilation
+3. ✅ **Avoid clean builds** (saves 1-2 minutes) - Uses Go's build cache

+# Author Module Guide
+
+## What Does This Do?
+
+The Author module turns your video files into DVDs that'll play in any DVD player - the kind you'd hook up to a TV. It handles all the technical stuff so you don't have to worry about it.
+
+---
+
+## Getting Started
+
+### Making a Single DVD
+
+1. Click **Author** from the main menu
+2. **Files Tab** → Click "Select File" → Pick your video
+3. **Settings Tab**:
+   - DVD or Blu-ray (pick DVD for now)
+   - NTSC or PAL - pick NTSC if you're in the US
+   - 16:9 or 4:3 - pick 16:9 for widescreen
+4. **Generate Tab** → Click "Generate DVD/ISO"
+5. Wait for it to finish, then burn the .iso file to a DVD-R
+
+That's it. The DVD will play in any player.
+
+---
+
+## Content Types: Feature, Extras, Galleries
+
+The Author module treats every import as a **content type**, not just a file:
+
+- **Feature**: the main movie title (supports chapters and chapter menus)
+- **Extra**: bonus video titles (no chapters, separate DVD titles)
+- **Gallery**: still-image slideshows (photos, artwork, stills)
+
+### Default Behavior
+
+- All imported videos default to **Feature**
+- You can change each video’s **Content Type** using the per-item dropdown
+
+### Extras Subtypes
+
+Extras must be assigned a subtype so they can be grouped in menus:
+
+- Behind the Scenes
+- Deleted Scenes
+- Featurettes
+- Interviews
+- Trailers
+- Commentary
+- Other
+
+When a video is switched to **Extra**:
+
+- It is removed from Feature and chapter logic
+- It becomes a separate DVD title under **Extras**
+
+Galleries behave like DVD-accurate still slideshows:
+
+- Next / Previous image navigation
+- Optional auto-advance
+- Separate from videos and chapters
+
+---
+
+## Chapter Thumbnails (Automatic, Feature Only)
+
+Every **Feature** chapter gets a thumbnail image for the Chapters menu.
+
+### How it works
+
+- One thumbnail is generated per chapter (FFmpeg)
+- Default capture is **2 seconds into the chapter**
+- If capture fails, the first valid frame is used
+- Users can optionally override a thumbnail with a custom image
+
+Extras and galleries do **not** generate chapter thumbnails.
+
+---
+
+## Scene Detection - Finding Chapter Points Automatically
+
+### What Are Chapters?
+
+You know how DVDs let you skip to different parts of the movie? Those are chapters. The Author module can find these automatically by detecting when scenes change.
+
+### How to Use It
+
+1. Load your video (Files or Clips tab)
+2. Go to **Chapters Tab**
+3. Move the "Detection Sensitivity" slider:
+   - Move it **left** for more chapters (catches small changes)
+   - Move it **right** for fewer chapters (only big changes)
+4. Click "Detect Scenes"
+5. Look at the thumbnails that pop up - these show where chapters will be
+6. If it looks good, click "Accept." If not, click "Reject" and try a different sensitivity
+
+### What Sensitivity Should I Use?
+
+It depends on your video:
+
+- **Movies**: Use 0.5 - 0.6 (only major scene changes)
+- **TV shows**: Use 0.3 - 0.4 (catches scene changes between commercial breaks)
+- **Music videos**: Use 0.2 - 0.3 (lots of quick cuts)
+- **Your phone videos**: Use 0.4 - 0.5 (depends on how much you moved around)
+
+Don't stress about getting it perfect. Just adjust the slider and click "Detect Scenes" again until the preview looks right.
+
+### The Preview Window
+
+After detection runs, you'll see a grid of thumbnails. Each thumbnail is a freeze-frame from where a chapter starts. This lets you actually see if the detection makes sense - way better than just seeing a list of timestamps.
+
+The preview shows the first 24 chapters. If more were detected, you'll see a message like "Found 152 chapters (showing first 24)". That's a sign you should increase the sensitivity slider.
+
+---
+
+## Understanding the Settings
+
+### Output Type
+
+**DVD** - Standard DVD format. Works everywhere.
+**Blu-ray** - Not ready yet. Stick with DVD.
+
+### Region
+
+**NTSC** - US, Canada, Japan. Videos play at 30 frames per second.
+**PAL** - Europe, Australia, most of the world. Videos play at 25 frames per second.
+
+Pick based on where you live. If you're not sure, pick NTSC.
+
+### Aspect Ratio
+
+**16:9** - Widescreen. Use this for videos from phones, cameras, YouTube.
+**4:3** - Old TV shape. Only use if your video is actually in this format (rare now).
+**AUTO** - Let the software decide. Safe choice.
+
+When in doubt, use 16:9.
+
+### Disc Size
+
+**DVD5** - Holds 4.7 GB. Standard blank DVDs you buy at the store.
+**DVD9** - Holds 8.5 GB. Dual-layer discs (more expensive).
+
+Use DVD5 unless you're making a really long video (over 2 hours).
+
+---
+
+## Common Scenarios
+
+### Scenario 1: Burning Home Videos to DVD
+
+You filmed stuff on your phone and want to give it to relatives who don't use computers much.
+
+1. **Files Tab** → Select your phone video
+2. **Chapters Tab** → Detect scenes with sensitivity around 0.4
+3. Check the preview - should show major moments (birthday, cake, opening presents, etc.)
+4. **Settings Tab**:
+   - Output Type: DVD
+   - Region: NTSC
+   - Aspect Ratio: 16:9
+5. **Menu Tab** (optional):
+   - Enable DVD Menus if you want a playable menu
+6. **Generate Tab**:
+   - Title: "Birthday 2024"
+   - Pick where to save it
+   - Click Generate
+7. When done, burn the .iso file to a DVD-R
+8. Hand it to grandma - it'll just work in her DVD player
+
+### Scenario 2: Multiple Episodes on One Disc
+
+You downloaded 3 episodes of a show and want them on one disc with a menu.
+
+1. **Clips Tab** → Click "Add Video" for each episode
+2. Leave "Treat as Chapters" OFF - this keeps them as separate titles
+3. **Settings Tab**:
+   - Output Type: DVD
+   - Region: NTSC
+4. **Menu Tab**:
+   - Enable DVD Menus
+   - Menu Structure: Feature + Extras
+5. **Generate Tab** → Generate the disc
+6. The DVD will have a menu where you can pick which episode to watch
+
+### Scenario 3: Concert Video with Song Chapters
+
+You recorded a concert and want to skip to specific songs.
+
+Option A - Automatic:
+1. Load the concert video
+2. **Chapters Tab** → Try sensitivity 0.3 first
+3. Look at preview - if chapters line up with songs, you're done
+4. If not, adjust sensitivity and try again
+
+Option B - Manual:
+1. Play through the video and note the times when songs start
+2. **Chapters Tab** → Click "+ Add Chapter" for each song
+3. Enter the time (like 3:45 for 3 minutes 45 seconds)
+4. Name it (Song 1, Song 2, etc.)
+
+---
+
+## What's Happening Behind the Scenes?
+
+You don't need to know this to use the software, but if you're curious:
+
+### The Encoding Process
+
+When you click Generate:
+
+1. **Encoding**: Your video gets converted to MPEG-2 format (the DVD standard)
+2. **Timestamp Fix**: The software makes sure the timestamps are perfectly sequential (DVDs are picky about this)
+3. **Structure Creation**: It builds the VIDEO_TS folder structure that DVD players expect
+4. **ISO Creation**: If you picked ISO, everything gets packed into one burnable file
+
+### Why Does It Take So Long?
+
+Converting video to MPEG-2 is CPU-intensive. A 90-minute video might take 30-60 minutes to encode, depending on your computer. You can queue multiple jobs and let it run overnight.
+
+### The Timestamp Fix Thing
+
+Some videos, especially .avi files, have timestamps that go slightly backwards occasionally. DVD players hate this and will error out. The software automatically fixes it by running the encoded video through a "remux" step - think of it like reformatting a document to fix the page numbers. Takes a few extra seconds but ensures the DVD actually works.
+
+---
+
+## Troubleshooting
+
+### "I got 200 chapters, that's way too many"
+
+Your sensitivity is too low. Move the slider right to 0.5 or higher and try again.
+
+### "It only found 3 chapters in a 2-hour movie"
+
+Sensitivity is too high. Move the slider left to 0.3 or 0.4.
+
+### "The program is really slow when generating"
+
+That's normal. Encoding video is slow. The good news is you can:
+- Queue multiple jobs and walk away
+- Work on other stuff - the encoding happens in the background
+- Check the log to see progress
+
+### "The authoring log is making everything lag"
+
+This was a bug that's now fixed. The log only shows the last 100 lines. If you want to see everything, click "View Full Log" and it opens in a separate window.
+
+### "My ISO file won't fit on a DVD-R"
+
+Your video is too long or the quality is too high. Options:
+- Use a dual-layer DVD-R (DVD9) instead
+- Split into 2 discs
+- Check if you accidentally loaded multiple long videos
+
+### "The DVD plays but skips or stutters"
+
+This is usually because your original video had variable frame rate (VFR) - phone videos often do this. The software will warn you if it detects this. Solution:
+- Try generating again (sometimes it just works)
+- Convert the source video to constant frame rate first using the Convert module
+- Check if the source video itself plays smoothly
+
+---
+
+## File Size Reference
+
+Here's roughly how much video fits on each disc type:
+
+**DVD5 (4.7 GB)**
+- About 2 hours of video at standard quality
+- Most movies fit comfortably
+
+**DVD9 (8.5 GB)**
+- About 4 hours of video
+- Good for director's cuts or multiple episodes
+
+If you're over these limits, split your content across multiple discs.
+
+---
+
+## The Output Files Explained
+
+### VIDEO_TS Folder
+
+This is what DVD players actually read. It contains:
+- .IFO files - the "table of contents"
+- .VOB files - the actual video data
+
+You can copy this folder to a USB drive and some DVD players can read it directly.
+
+### ISO File
+
+Think of this as a zip file of the VIDEO_TS folder, formatted specifically for burning to disc. When you burn an ISO to a DVD-R, it extracts everything into the right structure automatically.
+
+---
+
+## Tips
+
+**Test Before Making Multiple Copies**
+Make one disc, test it in a DVD player, make sure everything works. Then make more copies.
+
+**Name Your Files Clearly**
+Use names like "vacation_2024.iso" not "output.iso". Future you will thank you.
+
+**Keep the Source Files**
+Don't delete your original videos after making DVDs. Hard drives are cheap, memories aren't.
+
+**Preview the Chapters**
+Always check that chapter preview before accepting. It takes 10 seconds and prevents surprises.
+
+**Use the Queue**
+Got 5 videos to convert? Add them all to the queue and start it before bed. They'll all be done by morning.

+# GStreamer Player Migration Plan
+
+**Goal:** Replace the broken FFmpeg pipe-based player with the robust GStreamer implementation.
+
+**Timeline:** 1-2 days (vs. weeks of debugging pipes)
+
+---
+
+## Phase 1: Make GStreamer a Core Dependency ✅ COMPLETE
+
+### What We Did
+- Updated `install.sh` to always install GStreamer dev libraries
+- Added verification checks for GStreamer presence
+- Updated `build-linux.sh` to require GStreamer and fail if missing
+- Updated `build.sh` to always use `-tags gstreamer`
+
+### Verification
+```bash
+# Check GStreamer is installed
+pkg-config --modversion gstreamer-1.0
+
+# Should show version like: 1.24.x
+```
+
+### Status
+✅ **COMPLETE** - Scripts updated, GStreamer is now mandatory
+
+---
+
+## Phase 2: Build and Verify GStreamer Works
+
+### Tasks
+1. **Install GStreamer** (if not already done)
+   ```bash
+   sudo dnf install -y \

+   Checking for GStreamer (required for player)...
+   GStreamer found (1.24.x)
+
+   Building VideoTools with GStreamer player...
+   Build successful!
+   ```
+
+3. **Test basic playback**
+   ```bash
+   ./VideoTools
+   # Go to Player module
+   # Load a test video
+   # Click Play
+   ```
+
+### Success Criteria
+- ✅ Build completes without GStreamer errors
+- ✅ VideoTools launches without crashes
+- ✅ Player module loads without errors
+- ✅ Can load a video file

+
+**Runtime Error: "gstreamer playbin unavailable"**
+- Solution: Install GStreamer plugins: `sudo dnf install gstreamer1-plugins-base`
+
+---
+
+## Phase 3: Remove UnifiedPlayer Completely
+
+### Tasks
+1. **Delete broken FFmpeg pipe player**
+   ```bash
+   git rm internal/player/unified_ffmpeg_player.go
+   git rm internal/player/unified_player_adapter.go

+   ```go
+   // Remove build tag (GStreamer is now always used)
+   package player
+
+   func newFramePlayer(config Config) (framePlayer, error) {
+       return NewGStreamerPlayer(config)
+   }
+   ```
+
+3. **Remove unused VTPlayer interface (if applicable)**
+   - Check if `vtplayer.go` interface is still needed
+   - If not, remove it
+
+4. **Clean up imports**
+   - Remove any references to UnifiedPlayer
+   - Run `gofmt` and verify build still works
+
+### Success Criteria
+- ✅ UnifiedPlayer files deleted
+- ✅ No references to UnifiedPlayer in codebase
+- ✅ Build still succeeds
+- ✅ Player still works
+
+### Verification
+```bash
+# Search for any remaining UnifiedPlayer references
+grep -r "UnifiedPlayer" internal/player/
+# Should return nothing (or only comments)
+
+# Rebuild and test
+./scripts/build.sh
+./VideoTools
+```
+
+---
+
+## Phase 4: Fill Gaps in GStreamer Implementation
+
+Your GStreamer player is already 90% complete, but let's verify and add missing pieces.
+
+### Current Status (from gstreamer_player.go)
+| Feature | Status | Line # |
+|---------|--------|--------|
+| Load video | ✅ Complete | 73-162 |
+| Play/Pause | ✅ Complete | 164-186 |
+| SeekToTime | ✅ Complete | 188-204 |
+| SeekToFrame | ✅ Complete | 206-214 |
+| GetFrameImage | ✅ Complete | 229-289 |
+| SetVolume | ✅ Complete | 291-301 |
+| GetCurrentTime | ✅ Complete | 216-227 |
+| Close/cleanup | ✅ Complete | 303-319 |
+
+### Missing Features to Add
+
+#### 4.1: Add GetDuration()
+```go
+func (p *GStreamerPlayer) GetDuration() time.Duration {
+    p.mu.Lock()
+    defer p.mu.Unlock()
+    if p.pipeline == nil {
+        return 0
+    }
+    var dur C.gint64
+    if C.gst_element_query_duration(p.pipeline, C.GST_FORMAT_TIME, &dur) == 0 {
+        return 0
+    }
+    return time.Duration(dur)
+}
+```
+
+#### 4.2: Add GetFrameRate()
+```go
+func (p *GStreamerPlayer) GetFrameRate() float64 {
+    p.mu.Lock()
+    defer p.mu.Unlock()
+    return p.fps
+}
+```
+
+#### 4.3: Add Stop() method
+```go
+func (p *GStreamerPlayer) Stop() error {
+    p.mu.Lock()
+    defer p.mu.Unlock()
+    if p.pipeline != nil {
+        C.gst_element_set_state(p.pipeline, C.GST_STATE_NULL)
+    }
+    return nil
+}
+```
+
+### Tasks
+1. Add missing methods above to `gstreamer_player.go`
+2. Ensure `framePlayer` interface in `frame_player.go` matches
+3. Update `UnifiedPlayerAdapter` if needed (or remove it - see Phase 3)
+4. Test each new method
+
+### Success Criteria
+- ✅ All interface methods implemented
+- ✅ Duration displays correctly in UI
+- ✅ Frame rate is accurate
+- ✅ Stop button works properly
+
+---
+
+## Phase 5: Test and Validate All Player Features
+
+### Test Matrix
+
+| Feature | Test Case | Expected Result |
+|---------|-----------|----------------|
+| **Load** | Drop video file | Video loads, shows duration |
+| **Play** | Click play | Smooth playback, no stuttering |
+| **Pause** | Click pause | Video freezes, audio stops |
+| **Seek** | Drag timeline | Jumps to position accurately |
+| **Frame Step** | Use arrow keys | Advances 1 frame at a time |
+| **Volume** | Adjust slider | Volume changes smoothly |
+| **Mute** | Click mute | Audio cuts off completely |
+| **Fullscreen** | Press F | Video fills screen |
+| **Multiple Formats** | Load MP4, MKV, AVI | All play correctly |
+| **High Resolution** | Load 4K video | Plays without freezing |
+| **Long Videos** | Load 2+ hour file | Seeking still accurate |
+
+### Performance Tests
+1. **CPU Usage** - Should be <20% during playback (check with `htop`)
+2. **Memory Leaks** - Run for 30 minutes, memory should stay stable
+3. **Frame Drops** - Monitor for dropped frames during playback
+
+### Integration Tests
+1. **Trim Module** - Load video, use frame-accurate seeking
+2. **Filters Module** - Apply filter, see real-time preview
+3. **Preview System** - Generate thumbnails quickly
+
+### Success Criteria
+- ✅ All test cases pass
+- ✅ No crashes during extended playback
+- ✅ Frame-accurate seeking works perfectly
+- ✅ CPU/Memory usage is reasonable
+- ✅ All video formats supported
+
+---
+
+## Timeline Estimate
+
+| Phase | Time | Blockers |
+|-------|------|----------|
+| Phase 1 ✅ | Done | None |
+| Phase 2 | 30 minutes | Installing GStreamer |
+| Phase 3 | 15 minutes | None (just deleting code) |
+| Phase 4 | 1-2 hours | Testing each method |
+| Phase 5 | 2-3 hours | Thorough testing |
+| **Total** | **4-6 hours** | **vs. weeks on pipes** |
+
+---
+
+## What Changed vs. Old Approach
+
+### Old Way (UnifiedPlayer with FFmpeg pipes)
+```
+❌ Manual pipe management
+❌ Manual A/V sync (never worked right)
+❌ Audio disabled to "fix" issues
+❌ Frame reading blocks UI
+❌ Seeking requires process restart
+❌ Weeks of debugging
+```
+
+### New Way (GStreamer)
+```
+✅ GStreamer handles pipes internally
+✅ Built-in A/V synchronization
+✅ Audio works out of the box
+✅ Non-blocking frame extraction
+✅ Native frame-accurate seeking
+✅ Hours of implementation
+```
+
+---
+
+## Rollback Plan (If Needed)
+
+If GStreamer has issues (unlikely):
+
+1. **Keep old code temporarily**
+   ```bash
+   git mv internal/player/unified_ffmpeg_player.go internal/player/unified_ffmpeg_player.go.bak
+   ```
+
+2. **Revert build scripts**
+   ```bash
+   git checkout HEAD -- scripts/build*.sh
+   ```
+
+3. **File issue with details**
+   - GStreamer version: `pkg-config --modversion gstreamer-1.0`
+   - Error message
+   - Test video format
+
+But honestly, your GStreamer code is solid. You won't need this.
+
+---
+
+## Key Decision Points
+
+### Should We Keep UnifiedPlayerAdapter?
+**Recommendation: DELETE IT**
+
+- It's a compatibility shim for the old player
+- GStreamerPlayer already implements the `framePlayer` interface
+- Extra layer adds complexity and bugs
+- Clean break is better
+
+### What About VTPlayer Interface?
+**Recommendation: SIMPLIFY**
+
+Current:
+```
+framePlayer interface (8 methods) ✅ Used by GStreamer
+VTPlayer interface (30+ methods) ❓ Overly complex
+```
+
+Keep `framePlayer`, remove or simplify `VTPlayer`.
+
+---
+
+## Post-Migration Cleanup
+
+Once everything works:
+
+1. **Update PROJECT_STATUS.md**
+   ```markdown
+   | Player | ✅ **Implemented** | GStreamer-based, stable playback |
+   ```
+
+2. **Update README.md**
+   - Add GStreamer to requirements
+   - Note improved player stability
+
+3. **Archive old commits**
+   ```bash
+   git tag archive/ffmpeg-pipe-player HEAD~20
+   git push origin archive/ffmpeg-pipe-player
+   ```
+
+4. **Unblock dependent modules**
+   - Start Trim module implementation
+   - Start Filters module implementation
+
+---
+
+## Emergency Contacts / Resources
+
+- **GStreamer Docs**: https://gstreamer.freedesktop.org/documentation/
+- **Go CGO Guide**: https://golang.org/cmd/cgo/
+- **Similar Projects**:
+  - Kdenlive (uses GStreamer with Qt)
+  - Pitivi (uses GStreamer with Python)
+
+---
+
+## Success Definition
+
+You'll know this migration is complete when:
+
+1. ✅ Build always uses GStreamer (no fallback)
+2. ✅ All player features work correctly
+3. ✅ No UnifiedPlayer code remains
+4. ✅ You can implement Trim module without player bugs
+5. ✅ PROJECT_STATUS.md shows Player as "Implemented"
+
+**Estimated completion: Tomorrow** (vs. weeks fighting pipes)

+# VideoTools Installation Guide for Linux, macOS, & WSL
+
+This guide provides detailed instructions for installing VideoTools on Linux, macOS, and Windows Subsystem for Linux (WSL) using the automated script.
+
+---
+
+## One-Command Installation
+
+The recommended method for all Unix-like systems is the `install.sh` script.
+
+```bash
+bash scripts/install.sh
+```
+
+This single command automates the entire setup process.
+
+### What the Installer Does
+
+1.  **Go Verification:** Checks if Go (version 1.21 or later) is installed and available in your `PATH`.
+2.  **Build from Source:** Cleans any previous builds, downloads all necessary Go dependencies, and compiles the `VideoTools` binary.
+3.  **Path Selection:** Prompts you to choose an installation location:
+    *   **System-wide:** `/usr/local/bin` (Requires `sudo` privileges). Recommended for multi-user systems.
+    *   **User-local:** `~/.local/bin` (Default). Recommended for most users as it does not require `sudo`.
+4.  **Install Binary:** Copies the compiled binary to the selected location and makes it executable.
+5.  **Configure Shell:** Detects your shell (`bash` or `zsh`) and updates the corresponding resource file (`~/.bashrc` or `~/.zshrc`) to:
+    *   Add the installation directory to your `PATH`.
+    *   Source the `alias.sh` script for convenience commands.
+
+### After Installation
+
+You must reload your shell for the changes to take effect:
+
+```bash
+# For bash users:
+source ~/.bashrc
+
+# For zsh users:
+source ~/.zshrc
+```
+
+You can now run the application from anywhere by simply typing `VideoTools`.
+
+---
+
+## Convenience Commands
+
+The installation script sets up a few helpful aliases:
+
+-   `VideoTools`: Runs the main application.
+-   `VideoToolsRebuild`: Forces a full rebuild of the application from source.
+-   `VideoToolsClean`: Cleans all build artifacts and clears the Go cache for the project.
+
+---
+
+## Manual Installation
+
+If you prefer to perform the steps manually:
+
+1.  **Build the Binary:**
+    ```bash
+    CGO_ENABLED=1 go build -o VideoTools .
+    ```
+
+2.  **Install the Binary:**
+    *   **User-local:**
+        ```bash
+        mkdir -p ~/.local/bin
+        cp VideoTools ~/.local/bin/
+        ```
+    *   **System-wide:**
+        ```bash
+        sudo cp VideoTools /usr/local/bin/
+        ```
+
+3.  **Update Shell Configuration:**
+    Add the following lines to your `~/.bashrc` or `~/.zshrc` file, replacing `/path/to/VideoTools` with the actual absolute path to the project directory.
+
+    ```bash
+    # Add VideoTools to PATH
+    export PATH="$HOME/.local/bin:$PATH"
+
+    # Source VideoTools aliases
+    source /path/to/VideoTools/scripts/alias.sh
+    ```
+
+4.  **Reload Your Shell:**
+    ```bash
+    source ~/.bashrc  # Or source ~/.zshrc
+    ```
+
+---
+
+## Uninstallation
+
+1.  **Remove the Binary:**
+    *   If installed user-locally: `rm ~/.local/bin/VideoTools`
+    *   If installed system-wide: `sudo rm /usr/local/bin/VideoTools`
+
+2.  **Remove Shell Configuration:**
+    Open your `~/.bashrc` or `~/.zshrc` file and remove the lines that were added for `VideoTools`.
+
+---
+
+## Platform-Specific Notes
+
+-   **macOS:** You may need to install Xcode Command Line Tools first by running `xcode-select --install`.
+-   **WSL:** The Linux instructions work without modification inside a WSL environment.

+# VideoTools Installation Guide for Windows
+
+This guide provides step-by-step instructions for installing VideoTools on Windows 10 and 11.
+
+---
+
+## Method 1: Automated Installation (Recommended)
+
+This method uses a script to automatically download and configure all necessary dependencies.
+
+### Step 1: Download the Project
+
+If you haven't already, download the project files as a ZIP and extract them to a folder on your computer (e.g., `C:\Users\YourUser\Documents\VideoTools`).
+
+### Step 2: Run the Setup Script
+
+1.  Open the project folder in File Explorer.
+2.  Find and double-click on `setup-windows.bat`.
+3.  A terminal window will open and run the PowerShell setup script. This will:
+    *   **Download FFmpeg:** The script automatically fetches the latest stable version of FFmpeg, which is required for all video operations.
+    *   **Install Dependencies:** It places the necessary files in the correct directories.
+    *   **Configure for Portability:** By default, it sets up VideoTools as a "portable" application, meaning all its components (like `ffmpeg.exe`) are stored directly within the project's `scripts/` folder.
+
+> **Note:** If Windows Defender SmartScreen appears, click "More info" and then "Run anyway". This is expected as the application is not yet digitally signed.
+
+### Step 3: Run VideoTools
+
+Once the script finishes, you can run the application by double-clicking `run.bat` in the main project folder.
+
+---
+
+## Method 2: Manual Installation
+
+If you prefer to set up the dependencies yourself, follow these steps.
+
+### Step 1: Download and Install Go
+
+1.  **Download:** Go to the official Go website: [go.dev/dl/](https://go.dev/dl/)
+2.  **Install:** Run the installer and follow the on-screen instructions.
+3.  **Verify:** Open a Command Prompt and type `go version`. You should see the installed Go version.
+
+### Step 2: Download FFmpeg
+
+FFmpeg is the engine that powers VideoTools.
+
+1.  **Download:** Go to the recommended FFmpeg builds page: [github.com/BtbN/FFmpeg-Builds/releases](https://github.com/BtbN/FFmpeg-Builds/releases)
+2.  Download the file named `ffmpeg-master-latest-win64-gpl.zip`.
+
+### Step 3: Place FFmpeg Files
+
+You have two options for where to place the FFmpeg files:
+
+#### Option A: Bundle with VideoTools (Portable)
+
+This is the easiest option.
+
+1.  Open the downloaded `ffmpeg-...-win64-gpl.zip`.
+2.  Navigate into the `bin` folder inside the zip file.
+3.  Copy `ffmpeg.exe` and `ffprobe.exe`.
+4.  Paste them into the root directory of the VideoTools project, right next to `VideoTools.exe` (or `main.go` if you are building from source).
+
+Your folder should look like this:
+```
+\---VideoTools
+    |   VideoTools.exe  (or the built executable)
+    |   ffmpeg.exe      <-- Copied here
+    |   ffprobe.exe     <-- Copied here
+    |   main.go
+    \---...
+```
+
+#### Option B: Install System-Wide
+
+This makes FFmpeg available to all applications on your system.
+
+1.  Extract the entire `ffmpeg-...-win64-gpl.zip` to a permanent location, like `C:\Program Files\ffmpeg`.
+2.  Add the FFmpeg `bin` directory to your system's PATH environment variable.
+    *   Press the Windows key and type "Edit the system environment variables".
+    *   Click the "Environment Variables..." button.
+    *   Under "System variables", find and select the `Path` variable, then click "Edit...".
+    *   Click "New" and add the path to your FFmpeg `bin` folder (e.g., `C:\Program Files\ffmpeg\bin`).
+3.  **Verify:** Open a Command Prompt and type `ffmpeg -version`. You should see the version information.
+
+### Step 4: Build and Run
+
+1.  Open a Command Prompt in the VideoTools project directory.
+2.  Run the build script: `scripts\build.bat`
+3.  Run the application: `run.bat`
+
+---
+
+## Troubleshooting
+
+-   **"FFmpeg not found" Error:** This means VideoTools can't locate `ffmpeg.exe`. Ensure it's either in the same folder as `VideoTools.exe` or that the system-wide installation path is correct.
+-   **Application Doesn't Start:** Make sure you have a 64-bit version of Windows 10 or 11 and that your graphics drivers are up to date.
+-   **Antivirus Warnings:** Some antivirus programs may flag the unsigned executable. This is a false positive.

+# Phase 2: GStreamer Integration Plan
+
+## Current State Analysis
+
+### Two Player Systems Found:
+
+1. **Player Module** (`main.go:6609`)
+   - Uses: `player.Controller` interface
+   - Implementation: `ffplayController` (uses external ffplay window)
+   - File: `internal/player/controller_linux.go`
+   - Problem: External window, not embedded in Fyne UI
+
+2. **Convert Preview** (`main.go:11132`)
+   - Uses: `playSession` struct
+   - Implementation: `UnifiedPlayerAdapter` (broken FFmpeg pipes)
+   - File: Defined in `main.go`
+   - Problem: Uses the UnifiedPlayer we're deleting
+
+## Integration Strategy
+
+### Option A: Unified Approach (RECOMMENDED)
+Replace both systems with a **single GStreamer-based player**:
+
+```
+GStreamerPlayer (internal/player/gstreamer_player.go)
+    ↓
+    ├──> Player Module (embedded playback)
+    └──> Convert Preview (embedded preview)
+```
+
+**Benefits:**
+- Single code path
+- Easier to maintain
+- Both use same solid GStreamer backend
+
+### Option B: Hybrid Approach
+Keep Controller interface, but make it use GStreamer internally:
+
+```
+Controller interface
+    ↓
+GStreamerController (wraps GStreamerPlayer)
+    ↓
+GStreamerPlayer
+```
+
+**Benefits:**
+- Minimal changes to main.go
+- Controller interface stays the same
+
+**We'll use Option A** - cleaner, simpler.
+
+---
+
+## Implementation Steps
+
+### Step 1: Create GStreamer-Based Controller
+File: `internal/player/controller_gstreamer.go`
+
+```go
+//go:build gstreamer
+
+package player
+
+import (
+    "fmt"
+    "time"
+)
+
+func newController() Controller {
+    return &gstreamerController{
+        player: NewGStreamerPlayer(Config{
+            PreviewMode: false,
+            WindowWidth: 640,
+            WindowHeight: 360,
+        }),
+    }
+}
+
+type gstreamerController struct {
+    player *GStreamerPlayer
+}
+
+func (c *gstreamerController) Load(path string, offset float64) error {
+    return c.player.Load(path, time.Duration(offset*float64(time.Second)))
+}
+
+func (c *gstreamerController) SetWindow(x, y, w, h int) {
+    c.player.SetWindow(x, y, w, h)
+}
+
+func (c *gstreamerController) Play() error {
+    return c.player.Play()
+}
+
+func (c *gstreamerController) Pause() error {
+    return c.player.Pause()
+}
+
+func (c *gstreamerController) Seek(offset float64) error {
+    return c.player.SeekToTime(time.Duration(offset * float64(time.Second)))
+}
+
+func (c *gstreamerController) SetVolume(level float64) error {
+    // Controller uses 0-100, GStreamer uses 0.0-1.0
+    return c.player.SetVolume(level / 100.0)
+}
+
+func (c *gstreamerController) FullScreen() error {
+    return c.player.SetFullScreen(true)
+}
+
+func (c *gstreamerController) Stop() error {
+    return c.player.Stop()
+}
+
+func (c *gstreamerController) Close() {
+    c.player.Close()
+}
+```
+
+### Step 2: Update playSession to Use GStreamer
+File: `main.go` (around line 11132)
+
+**BEFORE:**
+```go
+type playSession struct {
+    // ...
+    unifiedAdapter *player.UnifiedPlayerAdapter
+}
+
+func newPlaySession(...) *playSession {
+    unifiedAdapter := player.NewUnifiedPlayerAdapter(...)
+    return &playSession{
+        unifiedAdapter: unifiedAdapter,
+        // ...
+    }
+}
+```
+
+**AFTER:**
+```go
+type playSession struct {
+    // ...
+    gstPlayer *player.GStreamerPlayer
+}
+
+func newPlaySession(...) *playSession {
+    gstPlayer, err := player.NewGStreamerPlayer(player.Config{
+        PreviewMode:   true,
+        WindowWidth:   targetW,
+        WindowHeight:  targetH,
+        Volume:        1.0,
+    })
+    if err != nil {
+        // Handle error
+    }
+
+    return &playSession{
+        gstPlayer: gstPlayer,
+        // ...
+    }
+}
+```
+
+### Step 3: Update playSession Methods
+Replace all `unifiedAdapter` calls with `gstPlayer`:
+
+```go
+func (p *playSession) Play() {
+    p.mu.Lock()
+    defer p.mu.Unlock()
+
+    if p.gstPlayer != nil {
+        p.gstPlayer.Play()
+    }
+    p.paused = false
+}
+
+func (p *playSession) Pause() {
+    p.mu.Lock()
+    defer p.mu.Unlock()
+
+    if p.gstPlayer != nil {
+        p.gstPlayer.Pause()
+    }
+    p.paused = true
+}
+
+func (p *playSession) Seek(offset float64) {
+    p.mu.Lock()
+    defer p.mu.Unlock()
+
+    if p.gstPlayer != nil {
+        p.gstPlayer.SeekToTime(time.Duration(offset * float64(time.Second)))
+    }
+    p.current = offset
+    // ...
+}
+
+func (p *playSession) Stop() {
+    p.mu.Lock()
+    defer p.mu.Unlock()
+
+    if p.gstPlayer != nil {
+        p.gstPlayer.Stop()
+    }
+    p.stopLocked()
+}
+```
+
+### Step 4: Connect GStreamer Frames to Fyne UI
+
+The key challenge: GStreamer produces RGBA frames, Fyne needs to display them.
+
+**In playSession:**
+```go
+// Start frame display loop
+go func() {
+    ticker := time.NewTicker(time.Second / time.Duration(fps))
+    defer ticker.Stop()
+
+    for {
+        select {
+        case <-p.stop:
+            return
+        case <-ticker.C:
+            if p.gstPlayer != nil {
+                frame, err := p.gstPlayer.GetFrameImage()
+                if err == nil && frame != nil {
+                    fyne.CurrentApp().Driver().DoFromGoroutine(func() {
+                        p.img.Image = frame
+                        p.img.Refresh()
+                    }, false)
+                }
+            }
+        }
+    }
+}()
+```
+
+---
+
+## Module Integration Points
+
+### Modules Using Player:
+
+| Module | Usage | Status | Notes |
+|--------|-------|--------|-------|
+| **Player** | Main playback | ✅ Ready | Uses Controller interface |
+| **Convert** | Preview pane | ✅ Ready | Uses playSession |
+| **Trim** | Not implemented | ⏳ Waiting | Blocked by player |
+| **Filters** | Not implemented | ⏳ Waiting | Blocked by player |
+
+### After GStreamer Integration:
+- ✅ Player module: Works with GStreamerController
+- ✅ Convert preview: Works with GStreamerPlayer directly
+- ✅ Trim module: Can be implemented (player stable)
+- ✅ Filters module: Can be implemented (player stable)
+
+---
+
+## Build Order
+
+1. Install GStreamer (user runs command)
+2. Create `controller_gstreamer.go`
+3. Update `playSession` in `main.go`
+4. Build with `./scripts/build.sh`
+5. Test Player module
+6. Test Convert preview
+7. Verify no crashes
+
+---
+
+## Testing Checklist
+
+### Player Module Tests:
+- [ ] Load video file
+- [ ] Play button works
+- [ ] Pause button works
+- [ ] Seek bar works
+- [ ] Volume control works
+- [ ] Frame stepping works (if implemented)
+
+### Convert Preview Tests:
+- [ ] Load video in Convert module
+- [ ] Preview pane shows video
+- [ ] Playback works in preview
+- [ ] Seek works in preview
+- [ ] Preview updates when converting
+
+---
+
+## Rollback If Needed
+
+If GStreamer integration has issues:
+
+```bash
+# Revert controller
+git checkout HEAD -- internal/player/controller_gstreamer.go
+
+# Revert playSession changes
+git checkout HEAD -- main.go
+
+# Rebuild without GStreamer
+GOFLAGS="" ./scripts/build.sh
+```
+
+---
+
+## Success Criteria
+
+Phase 2 is complete when:
+- ✅ GStreamer installed on system
+- ✅ VideoTools builds with `-tags gstreamer`
+- ✅ Player module loads and plays videos
+- ✅ Convert preview shows video frames
+- ✅ No crashes during basic playback
+- ✅ Both systems use GStreamerPlayer backend

+# VideoTools Player Module
+
+## Overview
+
+The Player module provides rock-solid video playback with frame-accurate capabilities, serving as the foundation for advanced features like enhancement, trimming, and chapter management.
+
+## Architecture Philosophy
+
+**Player stability is critical blocker** for all advanced features. The current implementation follows VideoTools' core principles:
+- **Internal Implementation**: No external player dependencies
+- **Go-based**: Native integration with existing codebase
+- **Cross-platform**: Consistent behavior across Linux, Windows, macOS
+- **Frame-accurate**: Precise seeking and frame extraction
+- **A/V Sync**: Perfect synchronization without drift
+- **Extensible**: Clean interfaces for module integration
+
+## Critical Issues Identified (Legacy Implementation)
+
+### 1. Separate A/V Processes - A/V Desync Inevitable
+**Problem**: Video and audio run in completely separate FFmpeg processes with no synchronization.
+
+**Location**: `main.go:10184-10185`
+```go
+func (p *playSession) startLocked(offset float64) {
+    p.runVideo(offset)  // Separate process
+    p.runAudio(offset)  // Separate process
+}
+```
+
+**Symptoms**: 
+- Gradual A/V drift over time
+- Stuttering when one process slows down
+- No way to correct sync when drift occurs
+
+### 2. Command-Line Interface Limitations
+**Problem**: MPV/VLC controllers use basic CLI without proper IPC or frame extraction.
+
+**Location**: `internal/player/mpv_controller.go`, `vlc_controller.go`
+- No real-time position feedback
+- No frame extraction capability
+- Process restart required for control changes
+
+### 3. Frame-Accurate Seeking Problems
+**Problem**: Seeking restarts entire FFmpeg processes instead of precise seeking.
+
+**Location**: `main.go:10018-10028`
+```go
+func (p *playSession) Seek(offset float64) {
+    p.stopLocked()     // Kill processes
+    p.startLocked(p.current)  // Restart from new position
+}
+```
+
+**Symptoms**:
+- 100-500ms gap during seek operations
+- No keyframe awareness
+- Cannot extract exact frames
+
+### 4. Performance Issues
+**Problems**: 
+- Frame allocation every frame causes GC pressure
+- Small audio buffers cause underruns
+- Volume processing in hot path wastes CPU
+
+## Unified Player Architecture (Solution)
+
+### Core Design Principles
+
+1. **Single FFmpeg Process**
+   - Multiplexed A/V output to maintain perfect sync
+   - Master clock reference for timing
+   - PTS-based synchronization with drift correction
+
+2. **Frame-Accurate Operations**
+   - Seeking to exact frames without restarts
+   - Keyframe extraction for previews
+   - Frame buffer pooling to reduce GC pressure
+
+3. **Hardware Acceleration**
+   - CUDA/VA-API/VideoToolbox integration
+   - Fallback to software decoding
+   - Cross-platform hardware detection
+
+4. **Module Integration**
+   - Clean interfaces for other modules
+   - Frame extraction APIs for enhancement
+   - Chapter detection integration from Author module
+
+## Implementation Strategy
+
+### Phase 1: Foundation (Week 1-2)
+
+#### 1.1 Unified FFmpeg Process
+```go
+type UnifiedPlayer struct {
+    cmd           *exec.Cmd
+    videoPipe     io.Reader
+    audioPipe     io.Reader
+    frameBuffer   *RingBuffer
+    audioBuffer   *RingBuffer
+    syncClock     time.Time
+    ptsOffset     int64
+    
+    // Video properties
+    frameRate     float64
+    frameCount     int64
+    duration      time.Duration
+}
+
+// Single FFmpeg with A/V sync
+func (p *UnifiedPlayer) load(path string) error {
+    cmd := exec.Command("ffmpeg",
+        "-i", path,
+        // Video stream
+        "-map", "0:v:0", "-f", "rawvideo", "-pix_fmt", "rgb24", "pipe:4",
+        // Audio stream  
+        "-map", "0:a:0", "-f", "s16le", "-ar", "48000", "pipe:5",
+        "-")
+    
+    // Maintain sync internally
+}
+```
+
+#### 1.2 Hardware Acceleration
+```go
+type HardwareBackend struct {
+    Name     string  // "cuda", "vaapi", "videotoolbox"
+    Available bool
+    Device   int
+    Memory   int64
+}
+
+func detectHardwareSupport() []HardwareBackend {
+    var backends []HardwareBackend
+    
+    // NVIDIA CUDA
+    if checkNVML() {
+        backends = append(backends, HardwareBackend{
+            Name: "cuda", Available: true})
+    }
+    
+    // Intel VA-API
+    if runtime.GOOS == "linux" && checkVA-API() {
+        backends = append(backends, HardwareBackend{
+            Name: "vaapi", Available: true})
+    }
+    
+    // Apple VideoToolbox
+    if runtime.GOOS == "darwin" && checkVideoToolbox() {
+        backends = append(backends, HardwareBackend{
+            Name: "videotoolbox", Available: true})
+    }
+    
+    return backends
+}
+```
+
+#### 1.3 Frame Buffer Management
+```go
+type FramePool struct {
+    pool sync.Pool
+    active int
+    maxSize int
+}
+
+func (p *FramePool) get(w, h int) *image.RGBA {
+    if img := p.pool.Get(); img != nil {
+        atomic.AddInt32(&p.active, -1)
+        return img.(*image.RGBA)
+    }
+    
+    if atomic.LoadInt32(&p.active) >= p.maxSize {
+        return image.NewRGBA(image.Rect(0, 0, w, h)) // Fallback
+    }
+    
+    atomic.AddInt32(&p.active, 1)
+    return image.NewRGBA(image.Rect(0, 0, w, h))
+}
+```
+
+### Phase 2: Core Features (Week 3-4)
+
+#### 2.1 Frame-Accurate Seeking
+```go
+// Frame extraction without restart
+func (p *Player) SeekToFrame(frame int64) error {
+    seekTime := time.Duration(frame) * time.Second / time.Duration(p.frameRate)
+    
+    // Extract single frame
+    cmd := exec.Command("ffmpeg",
+        "-ss", fmt.Sprintf("%.3f", seekTime.Seconds()),
+        "-i", p.path,
+        "-vframes", "1",
+        "-f", "rawvideo",
+        "-pix_fmt", "rgb24",
+        "-")
+    
+    // Update display immediately
+    frame, err := p.extractFrame(cmd)
+    if err != nil {
+        return err
+    }
+    
+    return p.displayFrame(frame)
+}
+```
+
+#### 2.2 Chapter System Integration
+```go
+// Port scene detection from Author module
+func (p *Player) DetectScenes(threshold float64) ([]Chapter, error) {
+    cmd := exec.Command("ffmpeg",
+        "-i", p.path,
+        "-vf", fmt.Sprintf("select='gt(scene=%.2f)',metadata=print:file", threshold),
+        "-f", "null",
+        "-")
+    
+    return parseSceneChanges(cmd.Stdout)
+}
+
+// Manual chapter support
+func (p *Player) AddManualChapter(time time.Duration, title string) error {
+    p.chapters = append(p.chapters, Chapter{
+        StartTime: time,
+        Title:     title,
+        Type:      "manual",
+    })
+    p.updateChapterList()
+}
+
+// Chapter navigation
+func (p *Player) GoToChapter(index int) error {
+    if index < len(p.chapters) {
+        return p.SeekToTime(p.chapters[index].StartTime)
+    }
+    return nil
+}
+```
+
+#### 2.3 Performance Optimization
+```go
+type SyncManager struct {
+    masterClock    time.Time
+    videoPTS        int64
+    audioPTS        int64
+    driftOffset      int64
+    correctionRate  float64
+}
+
+func (s *SyncManager) SyncFrame(frameTime time.Duration) error {
+    now := time.Now()
+    expected := s.masterClock.Add(frameTime)
+    
+    if now.Before(expected) {
+        // We're ahead, wait precisely
+        time.Sleep(expected.Sub(now))
+    } else if behind := now.Sub(expected); behind > frameDur*2 {
+        // We're way behind, skip this frame
+        logging.Debug(logging.CatPlayer, "dropping frame, %.0fms behind", behind.Seconds()*1000)
+        s.masterClock = now
+        return fmt.Errorf("too far behind, skipping frame")
+    } else {
+        // We're slightly behind, catch up gradually
+        s.masterClock = now.Add(frameDur / 2)
+    }
+    
+    s.masterClock = expected
+    return nil
+}
+```
+
+### Phase 3: Advanced Features (Week 5-6)
+
+#### 3.1 Preview System
+```go
+type PreviewManager struct {
+    player    *UnifiedPlayer
+    cache     map[int64]*image.RGBA  // Frame cache
+    maxSize   int
+}
+
+func (p *PreviewManager) GetPreviewFrame(offset time.Duration) (*image.RGBA, error) {
+    frameNum := int64(offset.Seconds() * p.player.FrameRate)
+    
+    if cached, exists := p.cache[frameNum]; exists {
+        return cached, nil
+    }
+    
+    // Extract frame if not cached
+    frame, err := p.player.ExtractFrame(frameNum)
+    if err != nil {
+        return nil, err
+    }
+    
+    // Cache for future use
+    if len(p.cache) >= p.maxSize {
+        p.clearOldestCache()
+    }
+    p.cache[frameNum] = frame
+    
+    return frame, nil
+}
+```
+
+#### 3.2 Error Recovery
+```go
+type ErrorRecovery struct {
+    lastGoodFrame int64
+    retryCount    int
+    maxRetries    int
+}
+
+func (e *ErrorRecovery) HandlePlaybackError(err error) error {
+    e.retryCount++
+    
+    if e.retryCount > e.maxRetries {
+        return fmt.Errorf("max retries exceeded: %w", err)
+    }
+    
+    // Implement recovery strategy
+    if isDecodeError(err) {
+        return e.attemptCodecFallback()
+    }
+    
+    if isBufferError(err) {
+        return e.increaseBufferSize()
+    }
+    
+    return e.retryFromLastGoodFrame()
+}
+```
+

+}
+
+func (m *PlayerMetrics) Collect() {
+    // Real-time performance tracking
+    if frameDelivery := time.Since(frameReadStart); frameDelivery > frameDur*1.5 {
+        logging.Warn(logging.CatPlayer, "slow frame delivery: %.1fms", frameDelivery.Seconds()*1000)
+    }
+    
+    if audioBufferFillLevel := audioBuffer.Available() / audioBuffer.Capacity(); 
+       audioBufferFillLevel < 0.3 {
+        logging.Warn(logging.CatPlayer, "audio buffer low: %.0f%%", audioBufferFillLevel*100)
+    }
+}
+```

+# VideoTools Roadmap
+
+This roadmap is intentionally lightweight. It captures the next few high-priority goals without locking the project into a rigid plan.
+
+## How We Use This
+
+- The roadmap is a short list, not a full backlog.
+- Items can move between buckets as priorities change.
+- We update this at the start of each dev cycle.
+
+## Current State
+
+- dev21 focused on stylistic filters and enhancement module planning.
+- Filters module now includes decade-based authentic effects (8mm, 16mm, B&W Film, Silent Film, VHS, Webcam).
+- Player stability identified as critical blocker for enhancement development.
+- dev23 delivered UI cleanup (dropdown styling, settings panel polish, about/support layout).
+
+## Now (dev24 focus)
+
+- **Rock-solid video player implementation** - CRITICAL PRIORITY
+  - Fix fundamental A/V synchronization issues
+  - Implement frame-accurate seeking without restarts
+  - Add hardware acceleration (CUDA/VA-API/VideoToolbox)
+  - Integrate chapter detection from Author module
+  - Build foundation for frame extraction and keyframing
+  - Eliminate seeking glitches and desync issues
+
+- **Enhancement module foundation** - DEPENDS ON PLAYER
+  - Unified Filters + Upscale workflow
+  - Content-type aware processing (general/anime/film)
+  - Add blur control alongside sharpen/denoise
+  - AI model management system (extensible for future models)
+  - Multi-pass processing pipeline
+  - Before/after preview system
+  - Real-time enhancement feedback
+
+- **Upscale workflow parity**
+  - Replace Upscale output quality with Convert-style Bitrate Mode controls
+  - Ensure FFmpeg-based upscale jobs report progress in queue
+- **Authoring structure upgrade**
+  - Feature/Extras/Gallery content types with subtype grouping
+  - Chapter thumbnails auto-generated for Feature only
+  - Galleries authored as still-image slideshows under Extras
+
+## Next (dev25+)
+
+- **Enhancement module completion** - DEPENDS ON PLAYER
+  - Open-source AI model integration (BasicVSR, RIFE, RealCUGan)
+  - Model registry system for easy addition of new models
+  - Content-aware model selection
+  - Advanced restoration (SVFR, SeedVR2, diffusion-based)
+  - Quality-aware enhancement strategies
+
+- **Trim module with timeline interface** - DEPENDS ON PLAYER
+  - Frame-accurate trimming and cutting
+  - Manual chapter support with keyframing
+  - Visual timeline with chapter markers
+  - Preview-based trimming with exact frame selection
+  - Import chapter detection from Author module
+
+- **Professional workflow integration**
+  - Seamless module communication (Player ↔ Enhancement ↔ Trim)
+  - Batch enhancement processing through queue
+  - Cross-platform frame extraction
+  - Hardware-accelerated enhancement pipeline
+
+## Later
+
+- **Advanced AI features**
+  - AI-powered scene detection
+  - Intelligent upscaling model selection
+  - Temporal consistency algorithms
+  - Custom model training framework
+  - Cloud processing options
+
+- **Module expansion**
+  - Audio enhancement and restoration
+  - Subtitle processing and burning
+  - Multi-track management
+  - Advanced metadata editing
+
+## Versioning Note
+
+We keep continuous dev numbering. After v0.1.1 release, the next dev tag becomes v0.1.1-dev22 (or whatever the next number is).
+
+## Technical Debt and Architecture
+
+### Player Module Critical Issues Identified
+
+The current video player has fundamental architectural problems preventing stable playback:
+
+1. **Separate A/V Processes** - No synchronization, guaranteed drift
+2. **Command-Line Interface Limitations** - VLC/MPV controllers use basic CLI, not proper IPC
+3. **Frame-Accurate Seeking** - Seeking restarts processes with full re-decoding
+4. **No Frame Extraction** - Critical for enhancement and chapter functionality
+5. **Poor Buffer Management** - Small audio buffers cause stuttering
+6. **No Hardware Acceleration** - Software decoding causes high CPU usage
+
+### Proposed Go-Based Solution
+
+**Unified FFmpeg Player Architecture:**
+- Single FFmpeg process with multiplexed A/V output
+- Proper PTS-based synchronization with drift correction
+- Frame buffer pooling and memory management
+- Hardware acceleration through FFmpeg's native support

 # Rip Module
 
-Extract and convert content from DVDs, Blu-rays, and disc images.
+Extract and convert content from DVD folder structures and disc images.
 
 ## Overview
 
-The Rip module (formerly "Remux") handles extraction of video content from optical media and disc image files. It can rip directly from physical drives or work with ISO/IMG files, providing options for both lossless extraction and transcoding during the rip process.
+The Rip module focuses on offline extraction from VIDEO_TS folders or DVD ISO images. It is designed to be fast and lossless by default, with optional H.264 transcodes when you want smaller files. All processing happens locally.
 
-> **Note:** This module is currently in planning phase. Features described below are proposed functionality.
+## Current Capabilities (dev20+)
 
-## Features
+### Supported Sources
+- VIDEO_TS folders
+- ISO images (requires `xorriso` or `bsdtar` to extract)
 
-### Source Support
+### Output Modes
+- Lossless DVD -> MKV (stream copy, default)
+- H.264 MKV (transcode)
+- H.264 MP4 (transcode)
 
-#### Physical Media
-- **DVD** - Standard DVDs with VOB structure
-- **Blu-ray** - BD structure with M2TS files
-- **CD** - Video CDs (VCD/SVCD)
-- Direct drive access for ripping
+### Behavior Notes
+- Uses a queue job with progress and logs.
+- No online lookups or network calls.
+- ISO extraction is performed to a temporary working folder before FFmpeg runs.
+- Default output naming is based on the source name.
 
-#### Disc Images
-- **ISO** - Standard disc image format
-- **IMG** - Raw disc images
-- **BIN/CUE** - CD image pairs
-- Mount and extract without burning
+## Not Yet Implemented
+- Direct ripping from physical drives (DVD/Blu-ray)
+- Multi-title selection from ISO contents
+- Auto metadata lookup
+- Subtitle/audio track selection UI
 
-### Title Selection
+## Usage
 
-#### Auto-Detection
-- Scan disc for all titles
-- Identify main feature (longest title)
-- List all extras/bonus content
-- Show duration and chapter count for each
+1. Open the Rip module.
+2. Drag a VIDEO_TS folder or an ISO into the drop area.
+3. Choose the output mode (lossless MKV or H.264 MKV/MP4).
+4. Start the rip job and monitor the log/progress.
 
-#### Manual Selection
-- Preview titles before ripping
-- Select multiple titles for batch rip
-- Choose specific chapters from titles
-- Merge chapters from different titles
+## Dependencies
 
-### Track Management
+- `ffmpeg`
+- `xorriso` or `bsdtar` for ISO extraction
 
-#### Video Tracks
-- Select video angle (for multi-angle DVDs)
-- Choose video quality/stream
+## Example FFmpeg Flow (conceptual)
 
-#### Audio Tracks
-- List all audio tracks with language
-- Select which tracks to include
-- Reorder track priority
-- Convert audio format during rip
+- VIDEO_TS: concatenate VOBs then stream copy to MKV.
+- ISO: extract VIDEO_TS from the ISO, then follow the same flow.
 
-#### Subtitle Tracks
-- List all subtitle languages
-- Extract or burn subtitles
-- Select multiple subtitle tracks

-```
-
-## Tips & Best Practices
-
-### DVD Quality
-- Original DVD is 720×480 (NTSC) or 720×576 (PAL)
-- Always deinterlace DVD content
-- Consider upscaling to 1080p for modern displays
-- Use inverse telecine for film sources (24fps)
-
-### Blu-ray Handling
-- Main feature typically 20-50GB
-- Consider transcoding to H.265 to reduce size
-- Preserve 1080p resolution
-- Keep high bitrate audio (DTS-HD, TrueHD)
-
-### File Size Management
-| Source | Direct Copy | H.264 CRF 20 | H.265 CRF 24 |
-|--------|-------------|--------------|--------------|
-| DVD (2hr) | 4-8 GB | 2-4 GB | 1-3 GB |
-| Blu-ray (2hr) | 30-50 GB | 6-10 GB | 4-6 GB |
-
-### Legal Considerations
-- Ripping for personal backup is legal in many regions
-- Circumventing copy protection may have legal restrictions
-- Distribution of ripped content is typically illegal
-- Check local laws and regulations
-
-### Drive Requirements
-- DVD-ROM drive for DVD ripping
-- Blu-ray drive for Blu-ray ripping (obviously)
-- RPC-1 (region-free) firmware helpful
-- External drives work fine
-
-## Troubleshooting
-
-### Can't Read Disc
-- Clean disc surface
-- Try different drive
-- Check drive region code
-- Verify disc isn't damaged
-
-### Copy Protection Errors
-- Install libdvdcss (DVD) or libaacs (Blu-ray)
-- Update key database
-- Check disc region compatibility
-- Try different disc copy
-
-### Slow Ripping
-- Direct copy is fastest
-- Transcoding is CPU-intensive
-- Use hardware acceleration if available
-- Check drive speed settings
-
-### Audio/Video Sync Issues
-- Common with VFR content
-- Use -vsync parameter
-- Force constant frame rate
-- Check source for corruption
