Studio-grade AI lip sync, visual dubbing and voice cloning for film, ads and creator content
A model lineup spanning sync-3, lipsync-2-pro, lipsync-2 and react-1, handling side faces, occluded mouths, multiple faces per frame, low light and fast camera movement, up to 4K ProRes footage.
Keep the original performance and delivery while replacing the dialogue language, so a single shoot can serve global markets without reshooting the actor.
Generate the new voice track inside the platform or bring your own TTS API key; plan tiers include a set number of custom cloned voices.
A frame-accurate editor for cut, trim and split work, alongside a guided assistant where you describe the change you want and it configures the generation.

Studio-grade AI lipsync and visual dubbing, now with side-face and low-light support.
Purpose-built models that regenerate lips and facial movement to match new audio while preserving the actor's identity.
Replace dialogue with another language and resync the performance so the mouth matches the new speech.
Works with side faces, odd angles, multiple faces per shot, low light, fast camera movement and objects blocking the face.
Choose a drop-in lite mode, an assistant driven by plain-language descriptions, or a frame-accurate editing timeline.
