AI Video Character Swap

Keep the video. Change the star.

Upload your own 4–15 second reference video and one character image to replace its main subject while guiding the motion, camera, timing and original audio. Or choose Fateful Gaze: two characters face off across a crowded arena, and you can replace both roles with two images. The reference has no soundtrack. Generative details can vary, so review the result before publishing.
