Sync 3 is a video model by Sync Labs. In Endless it costs 420 credits per video and is available on every plan.
Sync 3 from Sync Labs replaces the speech in filmed footage and matches each mouth movement to it, reading the whole shot to handle difficult angles.
Sync 3 is the lip-sync model from Sync Labs, published in April 2026. Before it syncs anything, it reads the full shot: face position, lighting, head orientation and which person is talking. That lets it work on side profiles where part of the mouth is hidden, in uneven light, with handheld shake and on close-ups where small artifacts would show. It runs on footage up to 4K at 60 fps.
Post-production teams use it for visual dubbing, where the words change but the actor's timing, pauses and emotion stay. It also covers dialogue fixes on a finished edit and animating characters who were not speaking on camera. In Endless you upload the clip and the new speech; no prompt is needed.
Next to VEED Lipsync 2, which expects one speaker per scene and does best with faces toward the camera, Sync 3 is built for multi-speaker shots and harder angles. Both are available in chat and on the canvas, so you can compare them on the same footage with your workspace credits.
