Sync Lipsync v3 available on Artlist
Sync Lipsync v3 re-renders the mouth in existing footage or a still image to match a new audio track, up to 4K. It holds sync on profile angles and when hands or mics block the mouth.
What it does
Sync Lipsync v3 re-renders the mouth so it matches a new audio track, either on existing footage (up to 4K) or on a single still image. It processes the whole shot at once, which keeps sync on profile angles and when hands, mics or objects block the mouth.
Results and limits
Artlist says it holds sync where Lipsync v2 Pro slips. Listed limits: you can't control resolution or aspect ratio (the output matches the input), it needs a visible mouth, tiny faces and cluttered frames hurt quality, and if audio and video lengths differ it trims to the shorter one.
Worth knowing
Audio is required, and there's no text prompt. It takes video, JPEG/PNG/WebP images and mp3/wav/m4a/aac/ogg audio, and outputs MP4.
Try it yourself
Upload [shot with a clearly visible mouth] and [clean dialogue track of the same length, no music]. Run video-to-video and check the profile and occluded moments.
