ComfyUI: Configure sampling and window settings for long video generation
ComfyUI
Demo summary
The user walks through the Wan Video Wrapper sampling node, explaining how to set frame window size, motion frame overlap, and start steps for consistent video generation.
Step-by-step
- Locate the sampling section in the Wan Video Wrapper node
- Set the Frame Window Size to a value that is a multiple of 4 + 1 (e.g., 33 or 77)
- Adjust the Motion Frame Overlap to 9 or higher
- Set the Start Step to 0 for image-to-video generation
- Increase the Start Step to 2 or 3 for video-to-video generation
- Click Run
Options
- Increase overlap to 25 for greater smoothness
- Leave most settings at their default values
Watch out for
- Window size value must always be a multiple of 4 + 1
- Setting overlap below 9 results in noticeable choppiness
- Increasing overlap value will extend generation time
- For video input, you must increase start step to 2 or 3 to maintain consistency
Tips
- Use 33 or 77 as ideal window size values
- Keep the overlap frame number at 9 for a balance of speed and quality
Highlights
“the sampling section provided by One Video Wrapper is a bit more complex, though most settings can be left at their defaults”
