VidTwin: Video VAE with Decoupled Structure and Dynamics

CVPR 2025poster

Recent advancements in video autoencoders (Video AEs) have significantly improved the quality and efficiency of video generation. In this paper, we propose a novel and compact video autoencoder, VidTwin, that decouples video into two distinct latent spaces: Structure latent vectors, which capture ov…
