Lip sync: make a face in your video speak

Lip sync keeps your video as it is and re-animates the speaker's mouth so it matches new speech. Give it your own audio, or type the words and pick a voice. It is useful for dubbing, short explainers and fixing a line without reshooting.

Open Lip Sync

What you need

A video in which one face is clearly visible and roughly facing the camera.
The speech: an audio file, or typed text with a chosen voice and speed.
The right to use both the video and the voice.

Open Lip Sync in Frenz AI and add your video.
Add your audio, or type the words and choose a voice.

For a convincing result

Choose footage where the mouth is unobstructed — no hands, microphones or heavy shadow in front of it.
Match the speech length to the clip length.
Clean audio without music or background noise syncs better.

Price

Frenz AI runs on one credit balance shared by every tool. You can top up, or get a daily allowance with an AI plan. The exact price of a creation depends on the tool, its length and its quality, and it is shown before you confirm — nothing is charged until you do.
