AI Lip Sync
Match any mouth to any audio, up to 4K.
ManyMotions's AI lip sync makes a person in a video speak your audio: upload footage and a voice track, and the model re-renders the mouth to match every word. Choose precision or speed variants, or animate a still portrait into a talking video. It works up to 4K, which makes dubbed and re-voiced footage look native.

- 1Upload the video (or a face image) and the audio to match

Does it work on real footage?

Where does the audio come from?
Any audio you have: a recording, an AI voiceover generated on ManyMotions, or a translated track for dubbing.
