Seedance 2.5 style test: rooftop pursuit and a ledge hang with falling debris (20 s)
Night rooftop chase: two figures running, a ledge climb, a glass facade view with debris tumbling and a final empty roof.
Task: A tense night rooftop thriller.
Outcome: succeeded
0.84 s: Overhead of a roof with equipment.
2.51 s: Two figures run across gravel.
5.85 s: A figure climbs onto a parapet over a city.
10.87 s: Figure hangs from the ledge with a pack.
14.21 s: Glass facade with plants and debris falling.
17.56 s: Two figures at the ledge, one slipping.
19.23 s: Empty rooftop and dark sky.
Intent vs result: Ledge and pack continuity hold; the ending shows an empty roof, so the outcome is not shown.
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] Ending on an empty location leaves the story unresolved.
