- Add all necessary nodes: DualCLIPLoader, CogVideoImageEncode, CogVideoXVAELoader - Add negative prompt support (node 8) - Properly connect all nodes with links array (11 connections) - Workflow now fully functional for image-to-video generation Node flow: 1. LoadImage -> CogVideoImageEncode 2. DownloadAndLoadCogVideoModel -> CogVideoSampler (model) 3. DownloadAndLoadCogVideoModel -> CogVideoImageEncode (vae) 4. DualCLIPLoader -> CogVideoTextEncode (positive & negative) 5. CogVideoTextEncode (pos/neg) -> CogVideoSampler 6. CogVideoImageEncode -> CogVideoSampler (image conditioning) 7. CogVideoSampler -> CogVideoDecode 8. CogVideoXVAELoader -> CogVideoDecode 9. CogVideoDecode -> VHS_VideoCombine Version: 1.1.0
