Method & Evidence

AimTo develop an efficient and effective method for generating minute-scale, high-fidelity videos with precise camera control.

MethodDevelopment of a novel world modeling architecture (SANA-WM) incorporating hybrid linear attention, dual-branch camera control, a two-stage generation pipeline, and a robust annotation pipeline.

ProcedureThe SANA-WM model was designed with four core components: (1) Hybrid Linear Attention combining frame-wise Gated DeltaNet with softmax attention for efficient long-context modeling. (2) Dual-Branch Camera Control for precise 6-DoF trajectory adherence. (3) A Two-Stage Generation Pipeline with a long-video refiner for improved quality and consistency. (4) A Robust Annotation Pipeline for extracting accurate camera poses and action labels from public videos. The model was trained on approximately 213K public video clips with metric-scale pose supervision and evaluated on its ability to generate minute-scale videos.
