Do Video Generators Track the World Across Segments? A Benchmark and Method for World-State Reasoning in Video Continuation

arXiv · AI, language, vision and robotics · article · Sep 3, 2026 · UTC

Video generators build long videos by composing shorter parts, either by generating segments one after another or by autoregressively extending chunks. Each new part usually depends on memories of historical observations, such as recent frames, selected key frames, memory banks, or cached features. These memories preserve visible evidence from the past, but current generators do not reliably turn such evidence into a world-state interface: what holds in the video world after previous actions and how it should change under the next prompt. A past frame remains valid history, but it may not desc
