FAQs

What is Sync V3?
Sync V3 (sync-3) is Sync's flagship lip-sync model. It generates production-grade lip-sync at native 4K with shot-level understanding, obstruction handling, and accurate sync on extreme angles like profile and over-shoulder shots.
How is Sync V3 different from earlier lip-sync models?
Sync V3 builds full-shot spatial context rather than processing frames in independent chunks. The result is no flicker, no chunk-boundary artifacts, and accurate sync on angles and obstructions where older models break down.
What resolution does Sync V3 output?
Native 4K with built-in super-resolution at 25 fps. No separate upscale step needed for close-up or large-screen delivery.
Does Sync V3 handle obstructions like microphones and hands?
Yes. Sync V3 detects and works around obstructions in front of the mouth, keeping the sync accurate on the visible portion without warping the object itself.
How do I use Sync V3 on Morphic?
Open Copilot, attach the source video and the new audio track, and pick Sync V3. For dubbing, localization, or any clip where the mouth is in close-up, Sync V3 is the right pick over faster lower-fidelity options.
What languages does Sync V3 support?
Any language. Sync V3 is driven by the input audio, the model reads phoneme-level cues from the audio rather than picking from a language list, so any spoken language works.
