What is sync.?
sync. uses AI to match a video's lip movements to supplied or generated speech. It supports footage from films, podcasts, games, and animations, with models designed for scenes involving multiple faces, changing camera angles, low light, and partially obscured faces. Its visual dubbing tools adapt mouth movements to dialogue in another language while preserving the actor's performance.
Users can upload a video to the web studio and add speech through voice cloning, generated audio, or audio from the clip. Developers can integrate generation through a REST API and SDKs, while a Premiere plugin and ComfyUI node provide other workflow options. Audio dubbing supports 29 languages, and text-to-speech and custom voices are available through partner integrations.
Subscriptions combine a monthly fee with metered generation charges that vary by model. Plans set limits on video length, simultaneous jobs, and voice clones; higher tiers add team workspaces, usage discounts, and batch API processing. A separate verification tool checks whether a video was modified using sync.'s watermarking technology.
