Questions
How does AI lipsync work?
It finds the face in every frame and redraws the mouth area so it matches the sounds in your audio. Head movement, eyes, lighting and the rest of the shot stay as filmed.
Can I dub a video into another language?
Yes. Upload the video and a voiceover in the new language. The lips are matched to the new words, so the dub looks natural.
What makes the best result?
A clear, well-lit face looking roughly at the camera, with the mouth not covered. Clean speech without loud music in the audio also helps.
What if the audio and the video have different lengths?
Choose what should happen under If the lengths differ: loop or bounce the video, stretch it to the audio, stop at the shorter one, or keep both in full. The panel shows the result's length before you start.
There are several people in my video. Who gets synced?
Turn on Only the speaker and the lips of whoever is talking are synced. Otherwise the most visible face is used.
How much does it cost?
Lipsync is billed in credits per second of the result. You see the exact cost before you generate, and failed runs are refunded automatically.
