Inside the app
AI lip sync handles the mouth alongside the audio: supply or generate a new track, then align the lips to it. Review the result before adding subtitles and finishing the edit.
AI lip sync from your own audio
A typed script read by a catalogue voice, a voice you generated earlier, or a recording you made yourself.

Why it holds up
Dub into another language
Keep the footage and change the language, with a voice chosen for the delivery you want rather than the first one available.
Subtitles from the same audio
Transcription runs on the track you dubbed with, so captions and speech agree instead of describing the original.

Questions
Can I use AI lip sync on footage I filmed myself?
Yes. Import the clip from your camera roll and drive it with the audio you choose, the same way as a generated clip.
What is the difference between lip sync and dubbing here?
Lip sync re-matches the mouth to an audio track. Dubbing is the whole job — a new voice in a new language, with the mouth re-synced and captions regenerated to match.
Will the timing drift on a long clip?
Sync is generated against the supplied track rather than stretched to fit, and the timeline lets you nudge the result if a specific take needs it.
