Detailed iPhone guide
How to remove a person from a video on iPhone
The iPhone Photos editor does not provide a universal tool for removing any person from any video. This guide uses ObjectRemover in Safari: choose an MP4 or MOV from Photos, describe the unwanted person or object, wait for processing, and save the result. It is not a native iOS app, Photos extension, or offline tool.
