By specifying both the starting and ending visual states, the model utilizes its advanced spatiotemporal reasoning to synthesize logically consistent intermediate motion and transitions. This capability effectively eliminates the unpredictability of AI video endings, enabling precise execution of character actions, physical transformations, and complex camera movements. Whether for a 5 or 10-second sequence, it ensures cinematic continuity and natural blending, transforming random synthesis into a predictable, professional storytelling engine.
