AI BriefingAI Lip-Sync Model sync-3 Released
Key point
sync-3, an AI lip-sync model that uses 16B parameters to support emotional expression and 4K high-definition output, has been released.
Details
sync-3 is a 16B-parameter AI lip-sync model that goes beyond simple mouth movement to understand an actor's performance. Unlike existing models that stitch together individual snippets, it generates all frames at once based on a global understanding of the entire shot.
The model delivers stable performance even in close-ups, occlusion, extreme angles, and low-light environments—conditions where existing AI models have been weak—while preserving the emotion of the original performance.
Key features include:
- Support for 95+ languages
- 4K high-resolution output
- Available via website, API, or Adobe Premiere
