sync.

sync. is a specialized AI platform designed for high-quality video lipsync and visual dubbing. Its core offering centers on generating studio-grade lipsync animations that match spoken dialogue with precise mouth movements, enabling creators to seamlessly modify or translate video content without reshooting. The platform is built to handle complex real-world filming scenarios: it supports objects partially blocking the face, multiple faces in a single frame, multiple camera angles, low-light conditions, fast camera movements, and rapid dialogue exchanges. It accepts input up to 4K ProRes resolution, ensuring output retains professional video quality. Users can access sync.’s lipsyncing model through two primary channels: a RESTful API for automated pipeline integration, and a web studio interface for manual control and preview. The platform also offers dedicated “studio tools” — a set of plugins that fit into existing post-production workflows — allowing editors to apply lipsync adjustments within their usual editing environment. For projects requiring absolute precision, sync. provides a white-glove service where the team works directly with clients. A notable feature is its proprietary watermarking and verification system: users can upload any video to check whether it has been modified using sync.’s technology, enabling trust and authenticity in content that may have been altered. The lipsync model adapts to each actor’s unique performance, preserving emotional nuance, micro-expressions, and body language across multiple languages. Currently supported languages include English, Spanish, Hindi, French, German, and Korean, with expansion planned. The platform is aimed at film studios, advertising agencies, content creators, and localization teams who need to re-dub vid
