Seedance 2.5 anime test: 20 s rooftop confrontation that holds one pose for nine seconds before a lunge
Lantern-lit rooftop: a swordsman in the foreground and a suited figure with an umbrella behind, a long near-static opening, then a blurred lunge, a tumbling umbrella and a held standoff.
Task: A rooftop confrontation between a sword student and a former classmate at night in the rain, with an exact two-character cast.
Outcome: succeeded
0.84 s: A swordsman in a blue-grey kimono holds a long blade in the foreground; a suited figure with a black umbrella stands at the right beside a lantern; purple bokeh behind.
2.51 s: Near-identical to the first frame.
4.18 s: Near-identical.
5.85 s: Near-identical.
7.52 s: Near-identical.
9.20 s: Near-identical.
10.87 s: A motion-blurred lunge as two fighters cross.
12.54 s: Two figures in stances; an umbrella spins in the air.
14.21 s: The umbrella lies open on the floor; the fighters stand sword-length apart.
15.88 s: Same standoff.
19.23 s: Same standoff, a lantern at the right.
Intent vs result: The prompt specified exactly two characters; the sampled frames show a swordsman and a suited figure, so the cast count matches. The first six sampled frames (0.84-9.20 s) are near-identical, so about nine seconds read as a held pose in the sampled frames.
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 long structured prompt can produce a long held opening; if action is wanted early, put it early.
