Endless Wan 2.2 image-to-video workflow adds longer extensions
A Reddit post shares an updated ComfyUI workflow for Wan 2.2 image-to-video generation, now at v2.5.
- The workflow chains one 5-second initial block plus up to eight optional 5-second extension blocks
- In practice it can reach roughly 45 seconds of video, with some frame loss at the joins
- More extension blocks can be copied to go beyond that limit
- It can start from either an image or an existing video
- Each block has its own prompt selector, duration control, and fixed seed for isolated experimentation
- Supports multiple LoRA sections, low-VRAM GGUF loaders, and accelerated distilled LoRAs like Wan-Lightning
- v2.5 adds the ability to extend existing videos and removes leftover Crystools nodes for RTX 50xx compatibility
