LTXV Scene Extender - Task Progress

Phase 1: Core Infrastructure [COMPLETE]

• Create package structure
• time_manager.py - TimeManager class for frame/time abstractions
• script_parser.py - Script parsing for timestamped prompts, audio specs, guides
• audio_blender.py - AudioOverlapBlender for smooth transitions
• Unit tests for TimeManager - ALL PASS (10/10)
• Unit tests for script_parser - ALL PASS (16/16)
• __init__.py with v3 NODES registration

Phase 2: Main Node [IN PROGRESS]

• scene_extender.py - LTXVSceneExtender node skeleton (full features)
• scene_extender_mvp.py - LTXVSceneExtenderMVP (testable MVP!)
• Verify package loads in ComfyUI - PASS
• MVP: Single-chunk video generation with script parsing
• MVP: Image guide resolution from batch ($0, $1, etc.)
• Full: Multi-chunk looping for long videos
• Full: Audio generation integration
• Manual testing in ComfyUI

Phase 3: Timeline Editor [PLANNED]

• timeline_editor.py - Backend node
• js/timeline_editor.js - Lit-based frontend
• Drag-and-drop image markers (user requested)
• Waveform visualization

Phase 4: Documentation [PLANNED]

Package Import: SUCCESS - Both nodes detected

MVP Ready for Testing

The LTXVSceneExtenderMVP node is ready to test in ComfyUI:

1. Restart ComfyUI to load the new nodes
2. Find "LTXV Scene Extender (MVP)" in the node browser under "ErosDiffusion/ltxv"
3. Connect standard LTXV inputs (model, vae, sampler, sigmas, noise, guider)
4. Optionally provide:
   • guide_images: Batch of images referenced as $0, $1, etc.
   • scene_script: Timestamped prompt with guides
5. Generate!
