CubeComposer: Spatio-Temporal Autoregressive 4K 360{\deg} Video Generation from Perspective Video

CubeComposer is a new AI model that generates high-quality 4K 360-degree panoramic videos from regular perspective videos using a novel spatio-temporal autoregressive diffusion approach. The technology addresses computational limitations of existing methods by decomposing videos into cubemap representations, enabling native 4K resolution output for VR applications.
