Prepare these inputs before running

  • Prepare the required Source video, Source audio, Emotion, Movement before starting Lip Sync Ai.
  • Use a small representative source first; keep an untouched original for comparison.
  • State one desired change and a measurable pass condition instead of combining unrelated requests.

What a usable result should pass

  • Compare the Lip Sync Ai result with the untouched source at the same timestamps.
  • Inspect faces, edges, camera movement, reconstructed areas, and audio for new artifacts.
  • Reject the result if unrelated subjects, timing, framing, or approved content changed.

What this workflow may not guarantee

  • Generation can produce artifacts; inspect the result before publishing or delivering it.
  • Do not upload media or use a person, voice, logo, or copyrighted work without permission.
  • Short-video limits and source quality can prevent stable motion, faces, text, or audio.

What must work before publish

  • Required inputs are validated before a run starts.
  • Progress, errors, and retry state remain visible.
  • The result can be inspected before download.
  • Failed remote jobs do not consume credits.
