摘要

UltraGen Figure 1 . Typical video generation models exhibit significant quality degradation and increased processing time with higher resolutions, whereas our UltraGen delivers superior video quality at resolutions beyond 2K while achieving 4.78× speedup compared to the popular Wan-T2V-1.3B baseline [32] (81 frames, 4×H20 GPUs). Enlarge for better visual effects.
