Seedance 2.5 anime test: 20 s rain-soaked rooftop sword duel with a lightning flash and spark close-ups
Neon skyline silhouettes: two fighters sprint at each other, clash with sparks, a lightning bolt, a crossed-blade face-to-face close-up, then a wide return to a crouched standoff.
Task: A 2D hand-drawn action-anime rooftop sword duel at night in the rain above a neon city.
Outcome: succeeded
0.84 s: Wide: two tiny silhouettes on a wet rooftop, neon skyline behind.
4.18 s: The two fighters run toward each other.
5.85 s: They meet mid-frame, a long coat flaring at left.
7.52 s: Orange sparks scatter around the clash.
9.19 s: Both raise blades in silhouette.
10.86 s: A lightning bolt forks across the skyline.
12.53 s: Face-to-face close-up with crossed blades and a flare of sparks.
14.20 s: Same close-up with the faces nearer.
17.54 s: Wide again: both in low stances on the wet roof.
19.21 s: Same wide standoff held.
Intent vs result: The sampled frames reach a clear anime beat structure (approach, clash, lightning, close-up, standoff). Rain, reflections and spark particles are consistent with the intended look; fight choreography and animation timing are not rated.
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 wide-clash-closeup-wide pattern reads as anime shorthand in the sampled frames.
