Three rooftop sword duels in 2D anime: three prompt shapes, three shot structures

Three Seedance 2.5 runs of 8 August 2026 (UTC) stage a rain-soaked rooftop duel in 2D hand-drawn anime language with different prompt shapes: a shot-by-shot beat list, a prompt that asks for one unbroken shot, and a prompt with an exact two-character cast and a backstory. H01 viewed 12 timestamped frames of each. In the sampled frames: the beat-list run (9 detector transitions) goes wide, clash, lightning, crossed-blade close-up, then a wide standoff. The one-shot run (1 detector transition) sweeps from a neon sign close-up to a tower to the fight and up into the sky; whether it is truly one take cannot be settled from 12 frames. The two-character run (0 detector transitions) shows six near-identical sampled frames from 0.84 to 9.20 s before a motion-blurred lunge, so about nine seconds read as a held pose. Reading: the shot structure follows the prompt shape in these three single runs, with no seed set; a held opening in the third run suggests early action should be written as early action. This is a description of three runs, not a rule. These are retrospective observations of founder tests, not a benchmark or product validation. Audio was not listened to.
