Seedance 2.5 sequence run with one linked image: 20 s black hall with red veins, two figures on a stair and two close portraits
A black columned hall with red veins glowing in the stone: two figures on a stair and then close together, a close of a red-spiky-haired man with red eyes and bared teeth, a close of a long black-haired woman looking down and then with red eyes, and a closing two-shot seen from behind.
Task: Render a red-spiky-haired armoured man and a long-haired woman climbing a drowning black stair as a wet-stroke hero look, at 20 s.
Outcome: succeeded

"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 wet-stroke hero look), 20 s, 16:9, audio requested, no seed set. One of a set of sequence runs on 30 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 19.21 s of a 20.04 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.
