Swap what someone says without reshooting. Upload a video of a person talking and a new audio track, and Sync Lipsync reshapes the mouth movement to match the new words.

How it works

  1. Upload the video
  2. Upload the new voice track
  3. Generate and download the synced video

Tips for better results

  • Front-facing footage with a clearly visible mouth syncs best.
  • Make the voice track with text to speech if you do not have one.
  • Keep audio and video roughly the same length.

What people make with it

  • Dubbing into other languages
  • Fixing a line in a recorded video
  • Podcast and course clips

Questions

Can I lip sync someone else's video?

Only with their permission. Do not put words in real people's mouths without consent.

How long can the video be?

Up to 30 seconds, as an MP4 or MOV file. When the video and the voice track differ in length, the result is cut to the shorter one.

How much does it cost?

Each generation uses credits from your plan. The exact number shows on the Generate button before you spend anything, and failed generations are refunded automatically. New accounts get free credits to try it.
