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)

- App is a work in progress, nothing is ever 'final'
- Changed size references to just state the values without 'final'
- More accurate and less presumptive

Documents the complete snippet system redesign with dual output modes:
- "Snippet to Default Format": Stream copy mode for bit-perfect source preservation
- "Snippet to Output Format": Conversion preview using actual settings
Updates ai-speak.md with comprehensive snippet testing requirements and Jake's AI communication. Updates DONE.md with detailed feature breakdown, technical improvements, and bug fixes. Includes testing checklist for both snippet modes and batch generation.

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
- Updates automatically when preset changes
- 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
- Recommends "slow" as best quality/size ratio
- Prevents confusion about preset differences
- Enables informed decisions about encoding settings
Technical:
- All presets already supported by FFmpeg
- No changes to command generation needed
- Works with all video codecs (H.264, H.265, VP9, etc.)
- Preset names match FFmpeg standards
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
