Renamed "DVD Author" to "Author" for broader disc production workflow.
Created foundation for complete authoring pipeline with three main tasks:
**Module Structure:**
- Tabbed interface with Chapters, Rip DVD/ISO, and Author Disc tabs
- Added authorChapter struct (timestamp, title, auto-detected flag)
- Added author module state fields (file, chapters, threshold, detecting)
**Chapters Tab (Basic UI):**
- File selection with video probing integration
- Scene detection sensitivity slider (0.1-0.9 threshold)
- Placeholder UI for chapter list and controls
- Add Chapter and Export Chapters buttons (placeholders)
- Foundation for FFmpeg scdet scene detection
**Rip DVD/ISO Tab:**
- Placeholder for high-quality disc extraction
- Will support lossless ripping (like FLAC from CD)
- Preserve all audio/subtitle tracks
**Author Disc Tab:**
- Placeholder for VIDEO_TS/ISO creation
- Will support burn-ready output, NTSC/PAL, menus
Changes:
- Modified main.go: Added authorChapter struct, author state fields,
showAuthorView(), buildAuthorView(), buildChaptersTab(),
buildRipTab(), buildAuthorDiscTab()
- Modified internal/modules/handlers.go: Renamed HandleDVDAuthor to
HandleAuthor with updated comment
- Updated DONE.md with Author module skeleton details
Next steps: Implement FFmpeg scene detection, chapter list UI,
and DVD/ISO ripping functionality.

Added advanced audio channel remixing features for videos with imbalanced
left/right audio channels (e.g., music in left ear, vocals in right ear).
New audio channel options using FFmpeg pan filter:
- Left to Stereo: Copy left channel to both speakers
- Right to Stereo: Copy right channel to both speakers
- Mix to Stereo: Downmix both channels together evenly
- Swap L/R: Swap left and right channels
Changes:
- Updated audioChannelsSelect dropdown with 8 options (was 4)
- Implemented pan filter logic in all 4 FFmpeg command builders:
- buildFFmpegCommandFromJob (main convert)
- DVD encoding function
- Convert command builder
- Snippet generation
- Removed unused "os" import from internal/convert/ffmpeg.go
- Updated DONE.md with audio channel remixing feature
The pan filter syntax allows precise channel routing:
- pan=stereo|c0=c0|c1=c0 (left to both)
- pan=stereo|c0=c1|c1=c1 (right to both)
- pan=stereo|c0=0.5*c0+0.5*c1|c1=0.5*c0+0.5*c1 (mix)
- pan=stereo|c0=c1|c1=c0 (swap)

In Progress Tab Enhancements:
- Added animated striped progress bars to in-progress jobs
- Exported ModuleColor function for reuse across modules
- Shows real-time progress (0-100%) with module-specific colors
- Progress updates automatically as jobs run
- Maintains consistent visual style with queue view
Lossless Quality Preset Improvements:
- H.265 and AV1 now support all bitrate modes with lossless quality
- Lossless with Target Size mode now works for H.265/AV1
- H.264 and MPEG-2 no longer show "Lossless" option (codec limitation)
- Dynamic quality dropdown updates based on selected codec
- Automatic fallback to "Near-Lossless" when switching from lossless-capable
codec to non-lossless codec
Quality Options Logic:
- Base options: Draft, Standard, Balanced, High, Near-Lossless
- "Lossless" only appears for H.265 and AV1
- codecSupportsLossless() helper function checks compatibility
- updateQualityOptions() refreshes dropdown when codec changes
Lossless + Bitrate Mode Combinations:
- Lossless + CRF: Forces CRF 0 for perfect quality
- Lossless + CBR: Constant bitrate with lossless quality
- Lossless + VBR: Variable bitrate with lossless quality
- Lossless + Target Size: Calculates bitrate for exact file size with
best possible quality (now allowed for H.265/AV1)
Technical Implementation:
- Added Progress field to ui.HistoryEntry struct
- Exported StripedProgress widget and ModuleColor function
- updateQualityOptions() function dynamically filters quality presets
- updateEncodingControls() handles lossless modes per codec
- Descriptive hints explain each lossless+bitrate combination
This allows professional workflows where lossless quality is desired
but file size constraints still need to be met using Target Size mode.

Features:
- Add "×" delete button to each history entry in sidebar
- Click to remove individual entries from history
- Automatically saves and refreshes sidebar after deletion
Bug Fixes:
- Fix nil pointer crash when opening Convert module
- Fixed widget initialization order: bitrateContainer now created
AFTER bitratePresetSelect is initialized
- Prevented "invalid memory address" panic in tabs layout
Technical Details:
- Added deleteHistoryEntry() method to remove entries by ID
- Updated BuildHistorySidebar signature to accept onEntryDelete callback
- Moved bitrateContainer creation from line 5742 to 5794
- All Select widgets now properly initialized before container creation
The crash was caused by bitrateContainer containing a nil
bitratePresetSelect widget, which crashed when Fyne's layout system
called .Visible() during tab initialization.

- Fix panic when closing log viewer (duplicate channel close)
- Improve CBR: Set bufsize to 2x bitrate for better encoder handling
- Improve VBR: Increase maxrate cap from 1.5x to 2x target bitrate
- Add bufsize to VBR at 4x target (2x maxrate) to enforce caps
- Update VBR hint to reflect 2x peak cap and 2-pass encoding
This eliminates runaway bitrates while maintaining quality peaks.

Restructured bitrate controls to hide unused options based on mode,
and improved VBR encoding to use 2-pass for accurate bitrate targeting.
UI Improvements:
- Wrapped CRF, bitrate, and target size controls in hideable containers
- Only show relevant controls based on selected bitrate mode:
* CRF mode: Show only CRF entry
* CBR mode: Show only bitrate entry and presets
* VBR mode: Show only bitrate entry and presets
* Target Size mode: Show only target size controls
- Added descriptive hints for each mode explaining behavior
- Updated DVD mode to work with new container structure
- Made command preview update when bitrate settings change
Encoding Improvements:
- VBR now uses maxrate at 1.5x target for quality peaks
- VBR automatically enables 2-pass encoding for accuracy
- CBR remains strict (minrate=maxrate=target) for guaranteed bitrate
- Target Size mode continues to calculate exact bitrate from duration
This addresses runaway bitrate issues by:
1. Making it clear which mode is active
2. Hiding confusing unused controls
3. Ensuring VBR hits target average bitrate with 2-pass
4. Keeping CBR strict for exact constant bitrate
Pros of manual bitrate targeting:
- Predictable file sizes
- Meets strict size requirements
- Good for streaming with bandwidth constraints
Cons of manual bitrate targeting:
- Variable quality (simple scenes waste bits, complex scenes starve)
- Less efficient than CRF overall
- Requires 2-pass for VBR accuracy (slower)

Made the FFmpeg command preview less intrusive by adding a toggle button
and showing actual file paths instead of placeholders.
Changes:
- Added convertCommandPreviewShow state field to track preview visibility
- Added "Command Preview" toggle button next to "View Queue" button
- Command preview now hidden by default to save screen space
- Preview shows actual input/output file paths instead of INPUT/OUTPUT
