Synchronize visible speech in an existing video to a new audio track with Volcengine Video-to-Video Lip Sync. Upload a clear talking-face video and matching speech audio to create localized dubbing, translated dialogue, presenter updates, and revised voice tracks.
Keep the source performance and visual framing while adjusting visible mouth movement to follow a replacement audio track, producing a revised version of an existing talking video. Use translated or newly recorded speech to adapt presenters, lessons, product explainers, interviews, and social clips for another language or a corrected voice-over.
The model aligns mouth shapes and timing with the supplied voice while preserving the surrounding frames, making it useful when reshooting the original speaker is impractical. The workflow requires a source video with a visible speaking face and an audio file containing the target speech. Clear frontal footage and clean speech generally produce the most reliable result.
Choose a clip with a clearly visible face, limited occlusion, and stable framing around the speaking subject. Upload clean target audio with the intended dialogue and pacing. Trim long silence and confirm that the speech fits the source clip.
Generate the revised video, review mouth timing through the full clip, and download the result or retry with cleaner inputs.
