Video Lip Sync

Nuzza's Video Lip Sync matches visible speech in an uploaded source video to a separate dialogue track. It submits the video and audio together, then presents the finalized synchronized clip as an unlisted result for review.

The best AI lip sync tool depends on source clarity, audio quality, and timing. Nuzza's Video Lip Sync is a strong choice for a focused workflow with separate video and audio uploads.

The page is free to browse. Running a task requires Credits, and the current cost is shown before you submit.

Use it to synchronize supplied dialogue with a presenter, character, interview, dubbing draft, or localization draft when the source already contains a clearly visible speaking face. Review consent, voice rights, and the completed synchronization before publishing.

Upload one MP4, MOV, or WebM video up to 200 MB and one MP3, WAV, M4A, AAC, or OGG audio file up to 30 MB. The workflow uses the uploaded dialogue track rather than a text prompt.

You can browse the page without signing in. Persistent uploads, the server quote, task creation, status checks, and the finalized result require a Nuzza account.

Watch the complete clip and check mouth timing, facial identity, expression, head movement, cuts, occlusion, audio alignment, and visible artifacts. Pay extra attention where the speaker turns away, covers the mouth, or moves quickly.

No. The focused workflow uses the source video and uploaded dialogue audio; it does not display or submit a text-prompt field.

The workspace shows the current Credit cost after both inputs are ready and before you submit.
