A woman in a grey tank top on a lawn before a brick-and-glass entrance draws a yellow disc across her waist and throws it, then the camera whips down to the disc on a concrete step where a hand reaches in beside a white sneaker and lifts it.

Task: Stage a woman on a lawn who throws a yellow disc, a quick whip down to the disc on a concrete step and a hand and shoe that take it as one continuous live-action take of 7 s.

Outcome: succeeded

0.29 s: A woman in a grey tank top stands on a lawn before a brick-and-glass entrance, a yellow disc at her waist.
0.88 s: She steps and twists, the disc low at her side.
1.47 s: She extends her arm in a throw, one foot forward.
2.05 s: She stands with her arm lowered, weight on the front foot.
2.64 s: She stands, small in the frame; a blurred yellow shape crosses the lower left.
3.23 s: The camera whips down to a yellow disc lying on a concrete step.
3.81 s: Same; the disc lies still.
4.40 s: A black-trousered leg and a white sneaker enter at the right.
4.99 s: Same; a hand reaches in from the top right.
5.57 s: The hand touches the rim of the disc beside the sneaker.
6.16 s: The hand lifts the disc's edge.
6.75 s: The hand and disc are gone; the sneaker remains.

Intent vs result: The sampled frames follow the plan: a throw, a camera whip down to the disc and a hand and shoe taking it. The throw itself is seen as a posed arm extension. The linked inputs are recorded by count only; their disclosure and rights basis are unconfirmed, and the prompt asks that they set the faces and wardrobe of the people shown, so likeness is a hold. Spoken lines were requested and not heard.

Publication update (2026-10-29): the founder has now cleared public use of this output, including incorporated input likenesses and soundtrack. Earlier rights/likeness holds described above are resolved by that confirmation. Reference-input files remain private. Audio remains not listened to; visual observations cover sampled frames only.

One of a set of live-action school-scene runs on 25 September 2026 (UTC).

Evidence claims:
- [sourced_fact] Timestamped observations above come from viewing 12 sampled frames of the output (sampled visual inspection, not full playback).
- [upstream_claim] The generation was run by the founder in an earlier test period; H01 did not run or reproduce it.
- [inference] A whip from a throw to the landing spot connects two beats with one camera move.
