Five-shot version of the neon bout: wide silhouettes, a red-eyed young boxer, a punch exchange, an eye macro and a counter, then black from 18.9 s.

Task: Five escalating shots: the veteran's combo drives the kid to the ropes; the kid times one counter and ends it.

Outcome: succeeded

0.63 s: Wide of two silhouetted boxers in the laser-rope ring; held to 3.13 s.
4.39 s: Young boxer in red with red-lit eyes and a large cyan glove in the foreground.
8.15 s: Veteran's long punch with motion-blur copies; the young boxer takes it.
13.17 s: Extreme close-up of an eye with cyan cracking-glass lines.
15.68 s: Close-up of an eye with red streaks.
18.18 s: Wide with a red energy trail across the ring and sparks.
18.73 s: Last picture frame before black; black from 18.93 s.

Intent vs result: Blackdetect flags 18.875-20.0 s; the clip ends 1.1 s earlier than the ten-shot variants and holds fewer detector cuts (nine) than the ten-shot clips (14-18).

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 19 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 five-shot prompt yields longer holds per shot (the opening wide holds for 3 s), at the cost of a 1.1 s dead tail.
