Video Lip Sync
Video lip sync is for clips that already have performance in them — a presenter walking a product, a founder on a webcam, an actor in a medium shot. You keep every gesture. The model only rebuilds the mouth so a new line, a new language, or a cleaned-up take lands on the picture you already shot.
Three steps. That is the whole job.
- 1
Upload a video or photo
A clear, front-facing face works best. Or pick a sample in the studio.
- 2
Add audio or a script
Type the line and pick a voice, drop a file, or record. No timeline.
- 3
Generate lip sync
AI matches the mouth to every word. Then download the MP4.

Why people use video lip sync
Picture stay intact
Wardrobe, blocking, and camera move are untouched. The mouth pass is composited onto the original frames.
Dialogue replacement
Swap a paragraph without calling talent back. Drop the new WAV and generate over the same take.
Works with original sound or a new track
Keep room tone and rewrite lips, or replace the entire vocal with text-to-speech or a cloned read.
Portrait and wider shots
Best results on faces that fill enough of the frame for teeth and lip corners to be visible. Extreme profiles are weaker.
Three simple steps
- Step 1
Upload the clip
MP4, MOV, or WebM, up to several minutes depending on plan. A stable face beats a whip-pan.
- Step 2
Choose the audio source
Keep original sound, paste a rewritten script, or attach a new voiceover.
- Step 3
Render the synced take
Preview the mouth pass, then export. If a syllable is early, trim the audio and run again.
