## Version 0.1.0-dev12 (2025-12-02)
|
||||
|
||||
### Features
|
||||
- ✅ **Automatic hardware encoder detection and selection**
|
||||
- Prioritizes NVIDIA NVENC > Intel QSV > VA-API > OpenH264
|
||||
- Falls back to software encoders (libx264/libx265) if no hardware acceleration available
|
||||
- Automatically uses best available encoder without user configuration
|
||||
- Significant performance improvement on systems with GPU encoding support
|
||||
|
||||
- ✅ **iPhone/mobile device compatibility settings**
|
||||
- H.264 profile selection (baseline, main, high)
|
||||
- H.264 level selection (3.0, 3.1, 4.0, 4.1, 5.0, 5.1)
|
||||
- Defaults to main profile, level 4.0 for maximum compatibility
|
||||
- Ensures videos play on iPhone 4 and newer devices
|
||||
|
||||
- ✅ **Advanced deinterlacing with dual methods**
|
||||
- Added bwdif (Bob Weaver) deinterlacing - higher quality than yadif
|
||||
- Kept yadif for faster processing when speed is priority
|
||||
- Auto-detect interlaced content based on field_order metadata
|
||||
- Deinterlace modes: Auto (detect and apply), Force, Off
|
||||
- Defaults to bwdif for best quality
|
||||
|
||||
- ✅ **Audio normalization for compatibility**
|
||||
- Force stereo (2 channels) output
|
||||
- Force 48kHz sample rate
|
||||
- Ensures consistent playback across all devices
|
||||
- Optional toggle for maximum compatibility mode
|
||||
|
||||
- ✅ **10-bit encoding for better compression**
|
||||
- Changed default pixel format from yuv420p to yuv420p10le
|
||||
- Provides 10-20% file size reduction at same visual quality
|
||||
- Better handling of color gradients and banding
|
||||
- Automatic for all H.264/H.265 conversions
|
||||
|
||||
- ✅ **Browser desync fix**
|
||||
- Added `-fflags +genpts` to regenerate timestamps
|
||||
- Added `-r` flag to enforce constant frame rate (CFR)
|
||||
- Fixes "desync after multiple plays" issue in Chromium browsers (Chrome, Edge, Vivaldi)
|
||||
- Eliminates gradual audio drift when scrubbing/seeking
|
||||
|
||||
- ✅ **Extended resolution support**
|
||||
- Added 8K (4320p) resolution option
|
||||
- Supports: 720p, 1080p, 1440p, 4K (2160p), 8K (4320p)
|
||||
- Prepared for future VR and ultra-high-resolution content
|
||||
|
||||
- ✅ **Black bar cropping infrastructure**
|
||||
- Added AutoCrop configuration option
|
||||
- Cropdetect filter support for future auto-detection
|
||||
- Foundation for 15-30% file size reduction in dev13
|
||||
|
||||
### Technical Improvements
|
||||
- ✅ All new settings propagate to both direct convert and queue processing
|
||||
- ✅ Backward compatible with legacy InverseTelecine setting
|
||||
- ✅ Comprehensive logging for all encoding decisions
|
||||
- ✅ Settings persist across video loads
|
||||
|
||||
### Bug Fixes
|
||||
- ✅ Fixed VFR (Variable Frame Rate) handling that caused desync
|
||||
- ✅ Prevented timestamp drift in long videos
|
||||
- ✅ Improved browser playback compatibility
|
||||

## Critical Issues / Polishing for dev12
|
||||
## Priority Features for dev13 (Based on Jake's research)
|
||||
|
||||
### Quality & Compression Improvements
|
||||
- [ ] **Automatic black bar detection and cropping** (HIGHEST PRIORITY)
|
||||
- Implement ffmpeg cropdetect analysis pass
|
||||
- Auto-apply detected crop values
|
||||
- 15-30% file size reduction with zero quality loss
|
||||
- Add manual crop override option
|
||||
|
||||
- [ ] **Frame rate conversion UI**
|
||||
- Dropdown: Source, 24, 25, 29.97, 30, 50, 59.94, 60 fps
|
||||
- Auto-suggest 60→30fps conversion with size estimate
|
||||
- Show file size impact (40-45% reduction for 60→30)
|
||||
|
||||
- [ ] **HEVC/H.265 preset options**
|
||||
- Add preset dropdown: ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow
|
||||
- Show time/quality trade-off estimates
|
||||
- Default to "slow" for best quality/size balance
|
||||
|
||||
- [ ] **Advanced filters module**
|
||||
- Denoising: hqdn3d (fast), nlmeans (slow, high quality)
|
||||
- Sharpening: unsharp filter with strength slider
|
||||
- Deblocking: remove compression artifacts
|
||||
- All with strength sliders and preview
|
||||
|
||||
### Encoding Features
|
||||
- [ ] **2-pass encoding for precise bitrate targeting**
|
||||
- UI for target file size
|
||||
- Auto-calculate bitrate from duration + size
|
||||
- Progress tracking for both passes
|
||||
|
||||
- [ ] **SVT-AV1 codec support**
|
||||
- Faster than H.265, smaller files
|
||||
- Add compatibility warnings for iOS
|
||||
- Preset selection (0-13)
|
||||
|
||||
### UI & Workflow
|
||||
- [ ] **Add UI controls for dev12 backend features**
|
||||
- H.264 profile/level dropdowns
|
||||
- Deinterlace method selector (yadif/bwdif)
|
||||
- Audio normalization checkbox
|
||||
- Auto-crop toggle
|
||||
|
||||
- [ ] **Encoding presets system**
|
||||

|
||||
- "Maximum Compression" preset (H.265, slower, CRF 24, 10-bit, auto-crop)
|
||||
- "Fast Encode" preset (medium, hardware encoding)
|
||||
- Save custom presets
|
||||
|
||||
- [ ] **File size estimator**
|
||||
- Show estimated output size before encoding
|
||||
- Based on source duration, target bitrate/CRF
|
||||
- Update in real-time as settings change
|
||||
|
||||
### VR & Advanced Features
|
||||
- [ ] **VR video support infrastructure**
|
||||
- Detect VR metadata tags
|
||||
- Side-by-side and over-under format detection
|
||||
- Preserve VR metadata in output
|
||||
- Add VR-specific presets
|
||||
|
||||
- [ ] **Batch folder import**
|
||||
- Select folder, auto-add all videos to queue
|
||||
- Filter by extension
|
||||
- Apply same settings to all files
|
||||
- Progress indicator for folder scanning
|
||||
|
||||
## Critical Issues / Polishing
|
||||
- [ ] Queue polish: ensure scroll/refresh stability with 10+ jobs and long runs
|
||||
- [ ] Direct+queue parity: verify label/progress/order are correct when mixing modes
|
||||
- [ ] Conversion error surfacing: include stderr snippet in dialog for faster debug
