Audio-based Lip Synchronization for Talking Head Video Editing In the Wild

VideoReTalking is a technology that can edit facial expressions in videos to match new audio. Imagine changing someone’s speech in a video without altering their original visuals!

They achieve this through a multi-step process. First, the system standardizes the facial expressions in the video. Then, using the new audio, it animates the lips to synchronize with the speech. Finally, it refines the video to make the edits appear natural.

This tech has the potential to be widely used, from creating funny dubbed videos to making educational materials more engaging by replacing the audio narration.
