Lip Sync

Lip Sync

Lip Sync adjusts mouth movements using video and selected audio. Start independently or from a completed audio/video translation language version. The result is saved as a separate project and does not replace the original translation.

Steps

1. Open Lip Sync and upload video or choose an existing source offered on the page. For translation versions, first complete the relevant video and dubbed-audio outputs.
2. Upload or select the audio to match, and check that speech corresponds to the picture.
3. Choose standard or fine mode, review the estimate and current restrictions, then submit.
4. Preview and download the result. The original project remains independently available.

Standard-mode requirements

• One real person on screen; cartoon facial proportions should be close to human proportions.
• Prefer a front-facing, unobstructed face with stable lighting. Recommended movement is within 45 degrees horizontally and 15 degrees vertically.
• The source must contain a valid video stream and must not be HDR. Duration must not exceed 30 minutes or the plan limit, whichever is lower. Free still has its 10-minute plan limit.

Fine mode and formats

Fine and standard mode have different restrictions. The standard-mode 30-minute rule does not automatically apply to fine mode. Fine mode still follows plan limits and submission validation. A selectable mode does not promise support for every multi-person, HDR, or heavily obstructed scene.

The video entry accepts MP4, MOV, WebM, AVI, and MKV. Both video and audio must be readable. Follow the current validation for source matching and submission eligibility.

Practical use

Clear, stable, unobstructed faces are better suited to processing. Lip sync does not rewrite translations or correct wrong speech. Confirm the audio first, and make subtitle or dubbing changes in the source translation project before creating a new result.
