What is AI Lip Sync?
Ever need to match someone's lips to different audio? That's what lip sync does. Upload your video and the new audio you want, and the AI automatically adjusts the mouth movements to match perfectly. No manual editing needed.
Super useful for dubbing videos in different languages, fixing videos where audio doesn't match, creating talking avatar videos, or making video podcasts more engaging. Saves you hours compared to doing it manually frame by frame.
Pick between two options: Lip Sync 1.0 is faster and cheaper (perfect for quick projects), while Lip Sync 2.0 gives you more realistic results (better for professional work). Both work well - just depends on your needs and budget.
