Hierarchical Masked 3D Diffusion Model for Video Outpainting

This paper introduces a hierarchical masked 3D diffusion model (M3DDM) that leverages mask modeling and global-frame cross‑attention to achieve temporally consistent video outpainting, proposes a hybrid coarse‑to‑fine inference pipeline to mitigate error accumulation in long videos, and demonstrates state‑of‑the‑art results on benchmark datasets.
