Mivo Sync is a browser-based lip sync tool for creators and teams that need video localization without reshooting. Upload a clear face video or portrait, add recorded audio, a script, or an AI voice, and the tool maps mouth movement to the new speech. It supports multilingual content, voice cloning, talking photos, real faces, cartoon characters, MP4 or MOV exports, and API access for production workflows. It is useful for courses, product videos, social ads, creator channels, and studio localization work.
