What AI says about BlockVid

BlockVid is a semi-AR block diffusion framework for generating high-quality, consistent minute-long videos, using semantic sparse KV caching, block forcing, and noise scheduling. It introduces LV-Bench, a fine-grained benchmark with dedicated metrics to evaluate long-range coherence in minute-long videos. The project is developed by DAMO Academy, Alibaba Group, and ZIP Lab at Zhejiang University.
