• Abstract: Perceptual studies demonstrate that conditional diffusion models excel at reconstructing video content aligned with human visual perception. Building on this insight, we propose a video compression framework that leverages conditional diffusion models for perceptually optimized reconstruction. Specifically, we reframe video compression as a conditional generation task, where a generative model synthesizes video from sparse, yet informative signals. Our approach introduces three key modules: (1) Multi-granular conditioning that captures both static scene structure and dynamic spatio-temporal cues; (2) Compact representations designed for efficient transmission without sacrificing semantic richness; (3) Multi-condition training with modality dropout and role-aware embeddings, which prevent over-reliance on any single modality and enhance robustness. Extensive experiments show that our method significantly outperforms both traditional and neural codecs on perceptual quality metrics such as Fr\'echet Video Distance (FVD) and LPIPS, especially under high compression ratios.

  Video Autoencoder (VAE) aims to compress pixel data into low-dimensional latent space, playing an important role in OpenAI's Sora. Most of existing VAEs inflate a pretrained image VAE into the 3D causal structure for temporal-spatial compression. We propose a new KTC architecture and a group causal convolution (GCConv) module to further improve video VAE (IV-VAE)

  We propose a model-based video compression (MVC) framework that regards scenes as the fundamental units for video sequences. Our proposed MVC directly models novel intensity variation of the entire video sequence in one scene, seeking non-redundant representations instead of reducing redundancy. Our method achieves up to a 20% reduction compared to the latest video standard H.266 and is more efficient in decoding than existing video coding strategies.
