Hi @zcfrank1st, we’ve recently added RV2V prompt enhancement (PE) and enabled it for reference-image editing in the web
demo. It uses both the reference image and a source-video frame to describe the requested appearance transfer while
preserving the source motion.

Could you try the updated demo with Prompt Enhancement enabled? Upload your reference photo and try:

Replace the person in the video with the man in the reference image. Match his appearance while preserving the
original motion, framing, and background.

If you’re running locally, please pull the latest main. Please let us know whether the updated PE improves your result;
if it still fails, sharing your prompt and a reproducible example would help us investigate.
