Seedance 2.5 reference-anchored test: 20 s pastel blossom valley following a crane to a waterfall
Powder-pink and mint valley with a river and mist, a crane skimming its reflection, a small bird over the valley, a crane flying at camera before a waterfall, then a tiny crane in a shaft of light.
Task: A silent-protagonist short in a pastel blossom valley with a mirror-calm river and mist.
Outcome: succeeded
0.84 s: Wide: a blossom valley of pink, mint and lavender with a calm river and a plateau.
4.18 s: A crane glides over the water, its reflection below.
5.85 s: The crane with a wake trail on the water.
7.52 s: Wide: a small crane over the valley and a mist bank.
10.87 s: The crane smaller against cliffs.
12.54 s: The crane flies toward the camera in front of a waterfall.
14.21 s: A ring of spray around the crane.
17.56 s: A tiny crane in a bright shaft of light at the waterfall top.
19.23 s: Same, still tiny.
Intent vs result: The sampled frames keep a consistent pastel palette across wide, low and frontal shots and the crane stays recognisable across scale changes.
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.

"procedure": "Seedance 2.5, one reference still used as the look-and-world anchor, a long structured prompt (one subject, a setting and a shot-by-shot format), 20 s, 21:9, audio requested, no seed set.

}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 single non-human protagonist (a bird) gave a clear through-line in the sampled frames.
