ComfyUI: Preparing character reference images
ComfyUI
Demo summary
The creator demonstrates resizing and padding a target character image to match the video aspect ratio using color padding to avoid distortion.
Step-by-step
- Upload the character image you want to replace in the video
- Resize the image to match the video dimensions
- Set 'keep proportion' to 'pad'
- Set 'color pad' to '127 127 127' to apply gray padding
- Set 'divisible by' and 'round to multiple' to the same value
Watch out for
- The 'divisible by' and 'round to multiple' values must match to prevent dimension mismatch errors during sampling
Tips
- Use color padding instead of stretching to keep proportions and avoid distortion
