Microsoft researchers have developed VASA-1, a method that uses a single photo and audio file to generate videos of speaking faces with natural mouth movements, facial expressions, and head movements in real-time. The model significantly outperformed previous methods in terms of audio synchronization of lip and head movements and video quality, delivering 512x512 pixel videos at up to 40 FPS with a latency of just 170ms on an Nvidia RTX 4090 GPU. However, Microsoft has decided not to release VASA-1 due to the potential for abuse, but plans to make further improvements for lifelike digital AI avatars for various applications.
Key Takeaways
- Microsoft researchers have developed VASA-1, a method that uses a single photo and audio file to generate videos of speaking faces with natural mouth movements, facial expressions, and head movements in real-time.
- The model was trained on a large amount of facial video data and significantly outperformed previous methods in terms of audio synchronization and video quality.
- VASA-1 delivers 512x512 pixel videos with up to 40 FPS and a latency of just 170ms on an Nvidia RTX 4090 GPU.
