Cyan-versus-red energy-glove boxing round with afterimage fist trails; fade-in from black, a flat grey frame at 19.35 s and a black tail from 19.5 s.

Task: Ten fast shots telling one round: veteran's pressure, the young boxer's counter, the veteran rising, a final mutual charge, with a laser-rope ring.

Outcome: partial

0.05 s: Black frame; glowing eyes appear by 0.40 s.
3.13 s: Wide of two silhouettes in a laser-rope ring.
5.64 s: Cyan and red gloves clash in close-up.
8.15 s: Veteran's cyan punch with a trailing afterimage; the young boxer guards.
10.66 s: Close on the young boxer's red-lit eyes between his gloves.
14.42 s: Wide frame shows four figures around the ring (two left, two right); may be afterimage trails, uncertain at this size - prompt required exactly two.
16.93 s: Veteran with cyan gloves, glowing eyes, staring at camera.
19.35 s: Flat grey frame; black from 19.55 s.

Intent vs result: Blackdetect finds 0.00-0.25 s and 19.50-20.00 s; detector reports 14 transitions with several within 0.1 s (impact flashes), so shot count cannot be read from the detector.

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 22 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] The two-colour fighter palette and glove trails carry across ten-plus shots; the 14 s wide may show duplicate fighters, and the final half-second is spent on grey then black.
