An AI video face swap replaces a face in existing footage using a separate image or video as the face reference. Your Target Video supplies the scene and performance. Your Face Reference supplies the facial identity you want to add. When both uploads are videos, they still serve these two different roles.
Unlike a text-to-video generator, this tool starts with a clip rather than a written description. The aim is to change the face while retaining the surrounding performance—not to redesign the body, outfit, or setting. Results can vary, so check important details before sharing.
