What is sync.?

sync. is a cutting-edge video editing platform that revolutionizes how creators and developers work with video content. Built by Synchronicity Labs, the platform features lipsync-2, the world's most advanced lipsync technology that instantly synchronizes lip movements with any audio track without requiring training or fine-tuning. Users can upload any video, edit dialogue seamlessly by replacing audio, and leverage voice cloning from recordings, audio files, or text-to-speech generation. The technology works flawlessly across live-action footage, 2D and 3D animations, AI-generated characters, and even non-human subjects, with support for 4K resolution output. Beyond standard lipsync, the platform enables video translation into multiple languages, word-level dialogue editing, character re-animation, and realistic AI content generation. Accessible through an intuitive studio interface or developer-friendly API, sync. transforms labor-intensive post-production workflows into rapid, automated processes for film studios, content creators, marketers, game developers, and enterprises.
