Before you publish.
Compare identity, facial details, motion, camera movement, cuts and audio against the source throughout the video.
Review the quote before running. A failed generation releases its reserved credits. Download the results you want to keep; stored media is retained for 30 days.
Inputs and settings
Source video must be 5–30 seconds long, with no single shot longer than 15 seconds. Upload it so its duration can be priced before generation.
