Seven 10 s runs and two 20 s runs of the same youth football story: the 10 s versions end partway through the slide tackle in the sampled frames, the 20 s versions reach a goal and an ending.

Nine runs of 9 August 2026 (UTC) re-tell one youth football story in different character-design languages: seven at 10 s and two at 20 s (cinematic manhwa and retro 90s TV-anime). H01 viewed 12 timestamped frames of each.

Same in the sampled frames: spectators at a fence, a number-10 player controlling a high ball at sunset, boot-and-ball close-ups and a maroon rival's slide tackle. In all seven 10 s runs the sampled frames end during that tackle; the goal, the keeper and the kneeling ending appear only in the 20 s runs.

Different: outline weight and colour (a cyan glow outline, pastel retro, hand-inked, glossy 3D), background detail (a grandstand in the 3D version) and cast details such as spectators' clothing.

Reading: when a long structured prompt lists more beats than fit in the length, the clip stops partway through the list rather than compressing it, in this nine-run sample; this is an observation from single runs with no seed set.

Audio was not listened to.
