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.

Translate, dub, and lip-sync videos into 160+ languages
Translate videos and generate natural-sounding dubs using AI voice cloning, with multi-language output from a single project, glossaries, and a proofreading editor for translation quality control.
Automatically reshapes each speaker's mouth movements to match the translated speech, with support for uploaded audio in any language and options for selected video segments.
Detects text embedded in the video frame — captions, titles, labels, callouts — erases it, translates it, and rebuilds it in the new language while preserving layout, style, branding, and animation.
Produces translated or bilingual subtitle files, or burns styled subtitles directly into the video with custom fonts and the option to strip the original subtitle track.
