How It Works

1. Upload Your Video

Select a video file with a clearly visible face. The AI works best with well-lit, front-facing footage but handles a wide range of angles and video styles.

2. Add Your Audio

Upload the audio track you want to sync. Use a voice recording, AI-generated speech, or any audio file in a supported format. The tool supports any language.

3. AI Generates Lip Sync

The AI analyzes your audio frame by frame, detects facial landmarks, and generates precise mouth movements that match the speech. Processing takes seconds to minutes.

4. Export Your Video

Preview the result and download your lip synced video in MP4 format. No watermarks are added. Use the output in any project, commercial or personal.

Frequently Asked Questions

Is the lip sync generator really free to use? +

What video formats does the lip sync generator support? +
The generator supports all common video formats including MP4, MOV, AVI, and WebM. For best results, use MP4 with H.264 encoding. Videos should have a clearly visible face with good lighting and minimal obstructions for optimal lip sync accuracy.
What audio formats can I use? +
You can upload audio in MP3, WAV, AAC, M4A, and other standard formats. The audio should be clear speech without excessive background noise. Both recorded voice and AI-generated text-to-speech audio work well with the lip sync engine.
How long does it take to generate a lip synced video? +
Processing time depends on video length and resolution. Most videos under 2 minutes are processed within 30 seconds to a few minutes. Longer videos or higher resolutions may take slightly longer. The platform provides a progress indicator so you can track the status.

No. Videos created with Sync do not have watermarks, even on the free tier. You get clean, professional output that you can use in any context without visible branding or overlays.

How many languages does the lip sync generator support? +
The lip sync generator supports over 25 languages including English, Spanish, French, German, Portuguese, Chinese, Japanese, Korean, Hindi, Arabic, and more. The AI model is language-agnostic, meaning it matches mouth movements to any speech audio regardless of language.
