What does Lip sync 1 do?

Lip sync 1 is an AI lip sync generator that matches mouth movements in a video to a provided audio track. It automates timing and viseme mapping to produce natural-looking speech synchronization.

What videos work best for AI lip sync?

Talking-head or face-forward clips with clear mouth visibility work best. Good lighting, minimal motion blur, and steady framing help the artificial intelligence detect facial landmarks and improve sync accuracy.

Can I use my own voiceover or dubbed audio?

Yes. Upload your own voiceover, dialogue, or dubbed speech and generate a synced version of your clip. You can trim timing and regenerate quickly if you update the audio later.

How long does it take to generate lip sync?

Generation time depends on video length and quality, but most clips process quickly. Lip sync 1 is designed for fast iterations so you can preview, tweak, and export without long waits.

What can I export after generating?

Export a video file with the synced mouth movement and your chosen audio. The output is designed to be editor-friendly, so you can drop it into common video editing workflows or publish directly.
