FantasyTalking's Core Technology and Advantages
FantasyTalking is an open source project developed by the Fantasy-AMAP team. Its core technology is based on the innovative integration of the video diffusion model Wan2.1 and the audio encoder Wav2Vec. The system realizes three key breakthroughs:
- Uses advanced lip synchronization technology for precise conversion of audio to facial movements via the Wav2Vec audio encoder
- Equipped with a face-focused cross-attention module to ensure that facial features remain consistent throughout the video generation process
- Built-in motion intensity modulation module supports precise control of expression and movement amplitude
Compared with traditional solutions, the system supports secondary development through open-source model weights, and has obvious advantages in high-resolution output (720P) and diverse style support.
