Part of the dubbing pipeline
Available standalone here, and applied automatically inside full video dubbing runs.

FAQ
Questions people ask
What do I need to run lip-sync?
A video with a visible speaker and an audio track. If you do not have the audio yet, generate it in the same session with text to speech or a cloned voice.
Does lip-sync work in every language?
Yes. Sync is driven by the audio track, so it works for any of the 75+ languages Universe dubs into.
Is lip-sync included in video dubbing?
Yes. It runs as part of a full dubbing job. This page exists for when you only need the sync step on its own.
