Swap a person or character in my video

“Swap a person or character in my video”

The person's video with one person replaced by a chosen character (a made-up character, or a real person who recorded their consent) keeping the original motion, expressions, timing and lighting, or a character image made to perform the video's motion; the character stays the same across shots from its reference sheets, a face-only change is done by masked regeneration, and every result is labelled AI-generated with provenance.
