Replaced all emoji characters with standard ASCII status prefixes
to prevent encoding issues on Windows systems:
- ✓/❌ → [OK]/[ERROR]
- ⚠️ → [WARN]
- 📦/🔨/🧹/⬇️/📥 → [INFO]
This ensures the script works correctly on all Windows configurations
regardless of console encoding settings.

Batch files interpret unescaped parentheses as block delimiters,
causing "was unexpected at this time" errors and improper branch
execution. All parentheses in echo statements are now escaped with ^.

Enhanced build.bat to automatically detect and offer to install all
required dependencies for users with minimal Windows dev environment:
- Check for winget availability (required for auto-installation)
- Detect and offer to install Git (recommended for development)
- Improved GCC/MinGW detection with fallback instructions
- Better error messages for users without winget
- Graceful degradation when automatic installation is not available
This ensures Jake and other users with just Go installed can run the
build script and get prompted to install everything needed automatically.

Fixed thumbnails not displaying:
- Added preview frame generation to Compare module
- Thumbnails now load asynchronously when videos are loaded
- Uses capturePreviewFrames() just like Convert module
- Thumbnails appear after brief generation delay
Added Clear All button:
- Positioned to the right of instructions text
- Clears both File 1 and File 2 slots
- Refreshes view to show empty state
- Low importance styling (not highlighted)
Layout improvements:
- Instructions row now uses Border layout
- Clear All button aligned to the right
- Clean, accessible button placement
Both videos now show thumbnails (240x135) automatically
when loaded, providing visual confirmation of loaded content.
Fixed issue where dragging single videos would overwrite existing data:
Smart slot filling logic:
- Single video dropped: Fills first empty slot (File 1 then File 2)
- If both slots full: Shows dialog asking user to Clear first
- Multiple videos dropped: Fills both slots (replaces existing)
Behavior changes:
1. Drag first video → goes to slot 1
2. Drag second video → goes to slot 2
3. Drag third video → shows "Both Slots Full" message
4. Drag 2+ videos together → replaces both slots
User experience improvements:
- No more accidental overwrites when loading one at a time
- Clear feedback when slots are full
- Can now build comparison by dragging videos individually
- Or drag both at once to start fresh
Main menu drag-and-drop to Compare tile:
- Already working correctly
- Loads both videos sequentially then shows module
- No changes needed to that path
This makes the Compare workflow much more intuitive and prevents
losing loaded video data when adding the second video.
Fixed critical bug where loading second video would overwrite first:
- Changed parallel goroutines to sequential loading
- Load file 1, then file 2, then refresh UI once
- Prevents race condition from multiple showCompareView() calls
- Both files now display correctly side by side
Added action buttons for each file:
- Copy Metadata button: Copies formatted metadata to clipboard
- Clear button: Removes video from slot and refreshes display
- Buttons arranged horizontally: Load | Copy | Clear
- Low importance styling for secondary actions
Changes to drag-and-drop handlers:
- Within Compare module: sequential loading, single refresh
- From main menu: already sequential, no changes needed
- Both paths now work correctly
This fixes the "second file overwrites first" issue and adds
the requested metadata copy and clear functionality.
Added comprehensive documentation on Linux/GNOME compatibility:
Known Issues:
- Double-click titlebar maximize is Fyne framework limitation
- Provided workarounds: Super+Up, maximize button, F11
- Window sizing issues have been fixed
Cross-platform goals:
- Smooth operation on Linux, macOS, Windows
- Single codebase with Fyne framework
- Respect native window manager behaviors
Testing matrix:
- GNOME/Fedora verified
- X11 and Wayland support
- Should work on KDE, XFCE, etc.
Development guidelines:
- Test on both X11 and Wayland
- Consider mouse and keyboard workflows
- Respect window manager tiling
- HiDPI display support
This documentation helps users understand current limitations
and provides context for cross-platform development priorities.
Created comprehensive plan for extracting video player into separate project:
Goals:
- Independent development of player features
- Tighter, more polished video controls
- Reusable component for other projects
- Keep VideoTools focused on video processing
Migration strategy:
1. Extract internal/player to new repo
2. Create clean API interface
3. Update VideoTools to use external package
4. Enhance controls in separate project
Future player improvements:
- Thumbnail preview on seek hover
- Frame-accurate stepping
- Playback speed controls
- Better keyboard shortcuts
- Timeline markers and more
This separation will allow both projects to evolve independently
while keeping the VideoTools codebase lean and focused.
Fixed window resizing issues for better cross-platform behavior:
Convert module video pane:
- Reduced video pane minimum from 460x260 to 320x180
- Removed rigid MinSize on outer container (commented out)
- Removed rigid MinSize on image element
- Set stage minimum to 200x113 (reasonable 16:9 minimum)
- Video pane now scales down allowing smaller windows
Compare module:
- Reduced thumbnail minimum from 320x180 to 240x135
- Reduced metadata scroll minimum from 300x200 to 250x150
- More compact layout allows better window resizing
Benefits:
- Window can now shrink to fit smaller screens
- Better behavior on tiling window managers
- More flexible for cross-platform (Windows, macOS, Linux)
- Content scales intelligently instead of forcing window size
Note: Double-click titlebar maximize is a Fyne framework limitation.
Maximize via window controls or OS shortcuts (F11, Super+Up) works.
Added window centering to improve initial presentation:
- Call w.CenterOnScreen() after setting window size
- Window now opens centered rather than at OS default position
- Maintains existing resizing and maximization support
The window is already maximizable via SetFixedSize(false).
Users can maximize using OS window controls (double-click
titlebar, maximize button, or OS shortcuts like F11/Super+Up).
Prevents long filenames from manipulating window size:
- Truncate filenames longer than 35 characters
- Smart truncation preserves file extension
- Format: "long-filename-na...mp4" instead of wrapping
- Falls back to simple truncation for very long extensions
- Removed text wrapping from labels (no longer needed)
Examples:
- "my-very-long-video-filename.mp4" → "my-very-long-video-fi....mp4"
- "short.mp4" → "short.mp4" (unchanged)
- "filename.mkv" → kept as-is if under 35 chars
This ensures the Compare module labels stay compact and
predictable regardless of filename length.
Resolved UI framing issues where metadata was crushed and not
taking available vertical space:
Layout improvements:
- Used container.NewBorder to make metadata areas expand properly
- Set minimum sizes for scroll containers (300x200)
- Removed outer VScroll - individual metadata areas now scroll
- Grid columns now properly fill available vertical space
- Instructions fixed at top, metadata expands to fill remaining space
Text wrapping fixes:
- Added fyne.TextWrapBreak to file labels
- Prevents long filenames from stretching the window horizontally
- Labels now wrap to multiple lines as needed
Architecture changes:
- Separated file headers (label + button) from content
- Each column uses Border layout: header at top, metadata fills center
- Metadata scroll containers have explicit minimum sizes
- Two-column grid properly distributes horizontal space
The layout now feels more modern with better space utilization
and smooth scrolling within the metadata panels.
Major improvements to Compare module user experience:
- Auto-populate metadata when files are loaded (no Compare button needed)
- Show video thumbnails for both files (320x180)
- Support drag-and-drop onto Compare tile from main menu
- Load up to 2 videos when dropped on Compare tile
- Show dialog if more than 2 videos dropped
- Files loaded via drag show immediately with metadata
Changes to handleModuleDrop:
- Added special handling for Compare module
- Loads videos into compareFile1 and compareFile2 state
- Shows module with files already populated
Changes to buildCompareView:
- Added thumbnail display with dark background placeholders
- Created helper functions: formatMetadata(), loadThumbnail(), updateFile1(), updateFile2()
- Initialize view with any preloaded files
- Removed manual Compare button - metadata shows automatically
- Button handlers now call update functions to refresh display
- Cleaner, more intuitive workflow
This addresses the user feedback that dragging videos onto Compare
didn't load the module, and adds the requested thumbnail previews.
The Compare module now has colored bars at the top and bottom matching
its pink visual identity from the main menu. This creates visual
consistency with the Convert module and strengthens the app's
overall design language.
Changes:
- Added top bar with back button using ui.TintedBar
- Added bottom bar with module color
- Restructured layout to use container.NewBorder
- Made content area scrollable
The colored bars use the module's color (#FF44AA pink) as defined
in modulesList and retrieved via moduleColor().
- Implement drag-and-drop file loading in Compare module
- Accepts up to 2 video files
- Shows dialog if more than 2 videos dropped
- Automatically loads first two videos
- Integrated into global window drop handler
- Enhance metadata display with organized sections
- FILE INFO: path, file size, format
- VIDEO: codec, resolution, aspect ratio, frame rate, bitrate,
pixel format, color space, color range, field order, GOP size
- AUDIO: codec, bitrate, sample rate, channels
- OTHER: duration, SAR, chapters, metadata
- Both file panels now show identical detailed information
Critical Bug Fix:
- H.264 profile and level were being applied globally (-profile:v, -level:v)
- When cover art is present, this affected the PNG encoder stream
- PNG encoder doesn't support H.264 profiles, causing exit code 234
- Error: "Unable to parse option value 'main'" on PNG stream
Solution:
- Use stream-specific specifiers when cover art present
- Apply -profile✌️0 and -level✌️0 instead of -profile:v / -level:v
- This targets only the first video stream (main video)
- PNG cover art stream (1:v) is unaffected
- Fixed in both executeConvertJob() and startConvert()
UI Fix:
- Long output filenames were stretching the settings panel
- Added outputHint.Wrapping = fyne.TextWrapWord
- Filename now wraps properly instead of expanding horizontally
Tested with:
- Video with embedded cover art
- H.264 profile=main encoding
- Long filename conversion
Mark auto-crop, frame rate conversion, and encoder presets as complete in TODO.md.
Add detailed feature descriptions to DONE.md for all three priority features.
This commit enhances the encoder preset selector with detailed information
about speed vs quality trade-offs for each preset option.
Preset Information:
- Ultrafast: ~10x faster than slow, ~30% larger files
- Superfast: ~7x faster than slow, ~20% larger files
- Very Fast: ~5x faster than slow, ~15% larger files
- Faster: ~3x faster than slow, ~10% larger files
- Fast: ~2x faster than slow, ~5% larger files
- Medium: Balanced baseline (default)
- Slow: ~2x slower than medium, ~5-10% smaller (recommended)
- Slower: ~3x slower than medium, ~10-15% smaller
- Very Slow: ~5x slower than medium, ~15-20% smaller
UI Enhancements:
- Dynamic hint label below encoder preset dropdown

- Visual icons for different speed categories:
- ⚡ Ultrafast/Superfast/Very Fast (prioritize speed)
- ⏩ Faster/Fast (good balance)
- ⚖️ Medium (baseline)
- 🎯 Slow/Slower (recommended for quality)
- 🐌 Very Slow (maximum compression)
Implementation:
- updateEncoderPresetHint() function provides preset details
- Called on preset selection change
- Initialized with current preset on view load
- Positioned directly under preset dropdown for visibility
Benefits:
- Helps users understand encoding time implications
- Shows file size impact of each preset

This commit implements the frame rate conversion feature with intelligent
file size estimation and user guidance.
Frame Rate Options:
- Added all standard frame rates: 23.976, 24, 25, 29.97, 30, 50, 59.94, 60
- Maintained "Source" option to preserve original frame rate
- Replaced limited [24, 30, 60] with full broadcast standard options
- Supports both film (24 fps) and broadcast (25/29.97/30 fps) standards
Size Estimation:
- Calculates approximate file size reduction when downconverting
- Shows "Converting X → Y fps: ~Z% smaller file" hint
- Example: 60→30 fps shows "~50% smaller file"
- Dynamically updates hint when frame rate or video changes
- Only shows hint when conversion would reduce frame rate
User Warnings:
- Detects upscaling (target > source fps)
- Warns with ⚠ icon: "Upscaling from X to Y fps (may cause judder)"
- Prevents confusion about interpolation limitations
- No hint shown when target equals source
Implementation:
- updateFrameRateHint() function recalculates on changes
- Parses frame rate strings to float64 for comparison
- Calculates reduction percentage: (1 - target/source) * 100
- Updates automatically when video loaded or frame rate changed
- Positioned directly under frame rate dropdown for visibility
Technical:
- Uses FFmpeg fps filter (already implemented)
- Works in both direct convert and queue execution
- Integrated with existing frame rate handling
- No changes to FFmpeg command generation needed
Benefits:
- 40-50% file size reduction for 60→30 fps conversions
- Clear visual feedback before encoding
- Prevents accidental upscaling
- Helps users make informed compression decisions

- Works in both direct convert and queue job execution
- Proper error handling for videos without black bars
- Defaults to center crop if X/Y offsets not specified
Technical Details:
- Uses FFmpeg cropdetect filter with threshold 24
- Analyzes last detected crop value (most stable)
- 30-second timeout for detection process
- Regex pattern: crop=(\d+):(\d+):(\d+):(\d+)
- Calculates pixel reduction for savings estimate
Benefits:
- 15-30% file size reduction with zero quality loss
- Automatic detection eliminates manual measurement
- Confirmation dialog prevents accidental crops
- Clear visual feedback during detection
