How it works

You provide

A video you uploaded and an audio track you uploaded (or one made with a voice capability).

You get back

Your video, lips matched to the audio.

What this means for you

  • Billed per second of your media, rounded up — a 12-second clip is 12 seconds.
  • Up to 60 seconds per run.
  • Both files come from your uploads or assets, so the length is measured, never guessed.
