What does sync.so do?
Sync is a specialized AI tool that lets you change what people say in videos after they've said it. You upload a video, provide new audio (by recording, uploading, or generating from text), and the AI seamlessly syncs the new speech to the person's lip movements. It works on live-action footage, animated characters, and even AI-generated content in resolutions up to 4K, making it a powerful post-production editor for spoken dialogue.
The tool stands out with its 'lipsync-2-pro' model, which can learn a speaker's unique style without requiring any prior training on their voice. This means you can achieve highly natural results quickly. It's not just a simple voiceover; the technology focuses on precisely matching the phonemes of the new audio to the lip shapes in the video. It's also available via a robust API, allowing developers to integrate this lipsyncing capability directly into their own applications and workflows.
This tool is a game-changer for content creators, filmmakers, and marketing teams who need to localize videos for different languages, fix errors in recorded dialogue, or create personalized video ads at scale. Real-world use cases include dubbing a documentary into Spanish, correcting a mispronounced word in a corporate training video, or creating multiple versions of a commercial with different voiceovers without reshooting.
