LatentSync Overview
LatentSync is a ByteHop developedOpen Source Audio Driver Lip Synchronization ToolIt is constructed based on the latent diffusion model of Stable Diffusion. It can combine the inputDirect audio and video compositingAccurately matched output video for lips without manual frame-by-frame adjustments.
Core Advantages Comparison
- technical architectureCombining Whisper to extract audio features + U-Net to generate video frames is more natural than traditional keypoint detection methods.
- end-to-end processing: Direct output of the complete video (no need to extract intermediate parameters first)
- language adaptation: Version 1.5 is optimized for Chinese language support (similar tools like Wav2Lip are mainly for English).
- Hardware friendly: inference requires only 6.8GB of video memory, reducing training requirements to 20GB (similar tools often require 24GB+)
- Open source and free: Full code and pre-trained models available (commercial programs such as Adobe Character Animator require a subscription)
