About Wav2Lip
Wav2Lip is an open-source lip sync model based on the research paper 'A Lip Sync Expert Is All You Need.' It works by taking any video and any audio track as input and generating a new video where the speaker's lip movements are synchronized to the provided audio. Because it runs locally, Wav2Lip supports any language without cloud API limitations and gives users complete control over their data and processing pipeline. The model is widely used by developers, researchers, and studios who need to integrate lip sync into custom workflows or who require data privacy guarantees. However, Wav2Lip requires technical expertise to set up, has specific hardware requirements for GPU-accelerated processing, and produces results that may need post-processing to match the visual quality of commercial alternatives. Sync (sync.so) is the commercial evolution of the Wav2Lip approach, building on the same foundational research while delivering production-ready quality, a managed cloud platform, and an API that eliminates the need for local GPU infrastructure.
