- Clean speech without music gives the most accurate mouth shapes.
- If the audio is longer than the video, the result stops at the end of the video.

AI Lip Sync — FAQ
Do I need permission?
Yes. You must have consent from the person shown and the owner of the voice, and you confirm this before every run. Don't use lip sync to impersonate or mislead.
How much does it cost?
It is charged in credits per second of video, shown before you start. If the service fails or times out, the credits are refunded automatically; a result blocked by our safety check is not refunded. See Pricing.
Which model should I use?
Sync 2.0 is the natural all-rounder up to 60 seconds; Sync 2.0 Pro has the most detailed mouth and teeth. Kling Lip Sync is cheapest for 2–10 second clips at 720p or higher.
What does Seedance lip sync do?
Seedance 2.0 re-generates the clip from your video and audio as references, so the person moves naturally while speaking. It needs a 480p–720p clip and MP3 or WAV audio.
