Mira (Mini-Sora) is an experimental project aimed at exploring the field of high-quality, long-duration video generation, particularly in the mimicking of the Sora style. Based on existing text-to-video (T2V) generation frameworks, Mira achieves breakthroughs in several key aspects: extended sequence length, enhanced dynamic properties, and maintenance of 3D consistency. Mira is still in the experimental phase and has room for improvement compared to more advanced video generation technologies such as Sora.
