`video.py` into a clean, modular system that creates beat-matched slideshows with pulse/bloom effects, supporting both classic and beat-aligned modes. + +## ✅ COMPLETED (Foundation Solid) +- [x] Modularize video.py (98% reduction: 1420 → 24 lines) +- [x] Implement parallel processing with auto-scaling workers +- [x] Fix masking system for foreground/background effects +- [x] Create working demos with real content +- [x] Test suite: 90/92 tests passing (97.8% success) +- [x] Cross-platform support (Linux/Windows GPU/CPU) + +--- + +## 📋 COMPLETE WORK PLAN + +### **PHASE 1: Fix Transitions Implementation** ⚠️ IN PROGRESS +**Goal**: Enable beat-matched transitions (currently falls back to hardcuts) + +**Tasks:** +1. **Fix Circular Import**: `video_transitions.py` calls facade instead of implementation +2. **Move Implementation**: Copy beat-aligned transitions code from `video.py.backup` to `video_transitions.py` +3. **Add Workers Support**: Implement parallel clip generation for transitions +4. **Test Transitions**: Verify `--preset music-video` works with smooth transitions +5. **Fix CLI Workers Parameter**: Re-enable workers parameter in CLI for transitions + +**Impact**: Unlocks full beat-matched functionality with visual transitions + +--- + +### **PHASE 2: Demo Content Creation** +**Goal**: Create comprehensive demo content showcasing all features + +**Tasks:** +1. **Source Demo Images**: Create/collect varied images (landscapes, portraits, abstract, VRChat) +2. **Source Demo Audio**: Collect music clips (electronic, rock, classical, ambient) +3. **Generate Preset Examples**: Create 1-minute demos for each preset combination +4. **Document Examples**: Create README with video links/screenshots +5. **Mask Generation**: Auto-generate masks for demo content +6. **Quality Assurance**: Verify all demos work with effects and masking + +**Deliverables**: +- Demo image library with masks +- Demo audio library +- Preset showcase videos +- User documentation +
