Face Swap
In short: Face swap is the replacement of one person's face with another in video or images, a technique distinct from lip sync which only modifies the mouth region of the original speaker.
About Face Swap
Face swapping replaces the entire face of a person in video with a different person's face, maintaining the original head movements and expressions but changing identity. This is fundamentally different from lip sync technology, which preserves the original person's face and identity while only modifying mouth movements to match new audio.
The distinction matters for both technical and ethical reasons: lip sync modifies a small region for legitimate dubbing and content creation purposes, while face swapping raises more significant concerns about identity misuse. Understanding this difference helps users choose the right technology for their needs.
