Visual dubbing and localization

Replace dialogue with a new track in any language. Lip-sync follows the new audio at production quality, even on profile or blocked shots.

Close-up dialogue and interviews

Native 4K and shot-level coherence make Sync V3 the right pick when the mouth is large in the frame and any artifact would be visible.

Music videos and concert footage

Handles microphones and hands in front of the mouth, so live-performance footage can be re-synced without manually masking obstructions.

Translation and dubbing pipelines

Drop into existing localization workflows, audio in, lip-synced video out, no per-language model selection required.

Overview

Sync V3 (branded as sync-3) is Sync's flagship lip-sync model, the most capable production-grade lip-sync currently available. Where earlier models process frames in independent chunks and produce subtle flicker at chunk boundaries, Sync V3 builds full-shot spatial context and generates all frames together. The practical effect: native 4K output with no flicker, accurate sync on profile and over-the-shoulder angles, and obstruction handling for microphones, hands, and other objects in front of the mouth. It's the right pick for dubbing, localization, and any close-up dialogue where artifacts would be visible.

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.
