Night rooftop dance sequence in barrel-distorted fisheye with a lowrider, rain and fireworks; consistent lead-dancer wardrobe and a final close-up, then a 1 s black tail.

Task: Strobe-chopped fisheye music video on a wet parking-garage deck at night: lead dancer in a teal puffer with gold chain, crew, lowrider.

Outcome: succeeded

0.63 s: Fisheye floor-level view of the deck with a casino skyline.
1.88 s: Lead dancer in a teal puffer stands centre; gold shoes.
3.13 s: Crew of about eight lines up behind her.
5.64 s: Macro of gold shoes on wet ground with spray.
8.15 s: Purple lowrider with open hood and chrome engine between dancers.
13.17 s: Extreme fisheye close-up of the lead's face with a gold chain.
15.68 s: Wide: car and dancers with sparklers.
18.89 s: Frontal close-up of the lead; black from 19.09 s.

Intent vs result: Black 19.04-20.0 s is the last second; detector cuts at 13.08, 14.08, 16.88 and 19.04 s. Fast-cut energy is carried by the effects, not by many hard cuts.

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] Fisheye plus a fixed wardrobe description kept the lead recognizable across macro, wide and close shots; budget the last second as a possible black tail.
