Seedance 2.5 sequence run with one linked image: 20 s black stair with red veins, two figures climbing and two strained close portraits
A black stair in a red-veined tower: a red-spiky-haired armoured man and a dark figure stumbling, a hunched dark figure, a red-lit tunnel of steps, a close of a red-haired man with bared teeth, a close of a long dark-haired woman with a red glow and the man's profile beside her, and two figures climbing.
Task: Render a red-haired man and a woman climbing a drowning black stair with red veins as a heavy wet-stroke look, at 20 s.
Outcome: succeeded
0.84 s: A black stair in a red-veined tower: a red-spiky-haired armoured man and a dark figure.
2.51 s: The two stumble.
4.18 s: Same.
5.85 s: A hunched dark figure on the steps.
7.52 s: A red-lit tunnel of steps with a hunched figure.
9.19 s: Close: a red-spiky-haired man, teeth bared, strained.
10.86 s: Same.
12.53 s: Close: a long dark-haired woman with a red glow, the man's profile at the right.
14.20 s: Same, her eyes red.
15.87 s: Two figures climbing the stair.
17.54 s: A figure in a black cloak from behind.
19.21 s: Two figures standing on the stair seen from behind, red veins at both sides.
Intent vs result: The sampled frames follow a wide, a close-up of each of two characters at about 9.2 to 14.2 s and a closing two-shot at about 15.9 to 19.2 s. One linked image input is recorded; its disclosure and rights basis are unconfirmed.
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 linked image input (a style reference; the prompt asks to take only its medium, palette and light), a long structured prompt with one scene in four parts (a wide of about 8 s, a close-up of each of two characters of about 4 s requesting spoken lines, and a closing two-shot) and a stated look target (a heavy wet-stroke look), 20 s, 16:9, audio requested, no seed set. One of a set of sequence runs on 31 August 2026 (UTC). Whether the requested lines were spoken was not checked (audio not listened to). Sampled inspection: 12 timestamped frames from 0.84 s to 19.23 s of a 20.06 s file, plus ffmpeg scene detection at threshold 0.30 and blackdetect.",

"limitations": [
"Sampled visual inspection from timestamped frames (contact sheets), not full real-time playback; motion smoothness, micro-timing and lip-sync are unrated.",
"Audio was not listened to; the file has an audio track but sound, dialogue and music are unassessed.",
"Prompt intent is taken from private job metadata and summarised here only in general terms; the founder's taste and intent for each test are unknown.",
"Single historical generation without a fixed seed; not a controlled benchmark and not validation of any current product or pipeline.",
"Request vs picture: the prompt asks for broad wet brushstrokes at the figure edges; at this size the frames read as a glossy render and few brush marks are visible."

}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] Red veins in black stone keep one colour in every shot.
