What audio formats work with Lipsync Studio?

Reelfo accepts MP3, WAV, and M4A audio files up to 60 seconds. You can also paste text to use built-in text-to-speech for quick prototyping before recording final voiceover.

Can I lip-sync to music instead of speech?

Yes. The system supports both speech and singing lip-sync. For music, it detects vocal timing and adjusts mouth shapes to match singing patterns, including sustained notes and vibrato.

How accurate is the lip-sync timing?

The AI processes audio at the phoneme level with frame-accurate alignment. Results are comparable to professional motion-capture lip-sync, though complex rapid speech may occasionally need prompt refinement.

Does lip-sync work with existing videos I upload?

Yes. You can upload a video of a person or character and apply new audio lip-sync to it. The AI detects the face in the video and modifies only the mouth region while preserving the rest.

Add natural lip-sync animation to any character video. Upload or record audio, and the AI generates precise mouth movements, jaw motion, and facial expressions that match your dialogue frame by frame.
