Start from a photo or a clip.Two ways to lip sync

From a photo

One photo and one voice track become a talking clip. HeyGen Avatar IV takes up to 3 minutes of audio and makes 9:16 or 16:9. Describe how the person moves, or leave it to the model.

From a clip

Keep the footage and change the words. Add the clip you filmed and a new voice track, and the mouth follows the new line. Sync 3 redubs clips up to 5 minutes long.

How AI lip sync worksIt listens for sounds, not words

Every sound has a mouth shape. The model hears which sound comes when, then redraws the lips, teeth and jaw in each frame to match. One sentence shows five of them.

Same words, another mood.Change the face, not only the mouth

Sync React-1 redubs a clip and sets the emotion as it goes: happy, angry, sad, neutral, disgusted or surprised. It can move the lips, the whole face or the head.

Clips and audio up to 15 seconds.

How to lip sync a videoThree steps, and what to watch

  1. 1

    Add the face

    Upload a photo or a clip, or pick a Persona. A face toward the camera, with the mouth in view and nothing in front of it, syncs best.

  2. 2

    Add the voice

    Upload a recording or a song, or generate a voiceover without leaving the tool. One voice at a time, with little background noise.

  3. 3

    Pick a model and run it

    If the audio is longer than the clip, choose what happens: cut it off, loop the clip, play it back and forth, hold still, or stretch it to fit.
