AI Lip Sync

How to Use AI Lip Sync

Pick a model, describe what you want, and preview the result in the same workspace.

1. 1

   Upload the source video you actually want to keep

   Start from the clip that already has the framing, speaker, and performance you want. This workflow expects one MP4 or MOV source video, so use the version you would otherwise have to re-edit or re-shoot.

2. 2

   Add one clean speech track

   Upload the audio line, dub, or narration you want the mouth movement to follow. Cleaner dialogue and fewer overlapping sounds make it easier to judge whether the sync landed.

3. 3

   Set the sync mode before you generate

   Use Cut Off when extra duration should be trimmed, Loop or Bounce when a repeated segment is acceptable, Silence when gaps should stay quiet, and Remap when you want the timing redistributed across the clip.

4. 4

   Review the result against the hardest moments

   Check plosives, pauses, fast syllables, and head turns first. If the drift only shows up near the end, change the sync mode before you replace the source assets.

What You Can Do with AI Lip Sync

Best used when the video already exists and the real task is AI lip sync for dubbing, dialogue replacement, multilingual localization, or talking-head revision.

• 01

  AI Lip Sync for dubbing and localization review

  Match a translated line or replacement voice track back onto an existing shot so you can review whether the new dialogue lands before a wider edit pass.

• 02

  AI Lip Sync for creator intros and talking-head revisions

  Update one spoken line, hook, or explainer segment without throwing away the framing and performance that were already working.

• 03

  AI Lip Sync for fixing short-form sync drift

  Use it when the edit is basically right but the mouth timing and the speech track no longer line up cleanly after a revision.
