ComfyUI: Image preparation for InfiniteTalk

Viraj Builds·Apr 2026

Demo summary

The video shows the process of loading a portrait image and resizing it to the specific 384x640 resolution required by the Wan video model using standard ComfyUI nodes.

Step-by-step

Use a standard ComfyUI image loader to load an image from your disk
Resize the image to 384 pixels width and 640 pixels height

Options

Use side profile images (though frontal is preferred)

Watch out for

The resolution must be a multiple of 16 to match the Wan video model requirements
Avoid images where the face is very small relative to the frame

Tips

Use frontal face images for the best performance and to avoid artifacts in lip sync
Select a portrait picture where the face is clearly visible and of a decent size
Use a 9:16 aspect ratio for standard portrait mode results
