What is SkyReels-A1?
SkyReels-A1 is a groundbreaking portrait animation framework that leverages video diffusion transformers to create expressive facial animations. The model combines advanced facial landmark extraction with conditional video generation to transfer expressions from video sequences onto static portrait images.
Implementation Details
The model employs a sophisticated architecture built upon DiT (Diffusion Transformers) that processes facial expression-aware landmarks as motion descriptors. It utilizes a VAE architecture with pose guidance mechanisms to maintain semantic integrity while transferring expressions.
