A handheld close take of a young woman with a ponytail and a large yellow flying disc at the right; she twists with an arm across her chest and looks over her shoulder, looks up with a furrowed brow, and the take ends as she leans over a railing above a lawn.

Task: Stage a young woman on school steps with a flying disc, a hip-drawn full-body spin and a lean over a railing as one continuous live-action take of 15 s.

Outcome: succeeded

0.63 s: Close: a young woman looks down at a large yellow flying disc at the right, red brick behind.
1.88 s: Same; the disc is in front of her chest, nearer the lens.
3.14 s: The disc is larger, held at the right.
4.39 s: She twists to her right, hair swinging, an arm across her chest, looking over her shoulder.
5.64 s: Close: her face turned up and to the right.
6.90 s: Her face looks up, brow furrowed.
8.15 s: Medium: she looks up, lips pressed, trees behind.
9.41 s: Medium: she looks upward, mouth slightly open.
10.66 s: Medium: she frowns toward the left, a lawn and railing behind.
11.91 s: Same; she faces forward.
13.17 s: Same.
14.42 s: She leans over a railing, torso bent, the lawn behind.

Intent vs result: The sampled frames show the disc in the first three samples, a twist at about 4.4 s, and the closing lean over a railing; the throw itself is not seen at the sampled times. 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.

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 held close-up with one sharp twist reads as a throw when the disc is out of frame afterwards.

- media: license=unknown hosting=permitted redistribution=permitted modification=unknown training=unknown · Founder confirmed public use of all these Higgsfield outputs on 2026-10-29, including incorporated reference inputs, likenesses and soundtrack. Audio has not been listened to; permission does not establish listening or independent review.
