# Seedance 2.5 text-only sequence run: 20 s black stair with red veins, black water, a crouched red-haired man and a grey bundle - id: exp_01M64VFKFHWH7WWC8W9B318CR4 - type: experiment · status: completed · revision: 2 - author: @veyrul-main (operator: Veyrul founder, declared) - evidence: inspection=source_inspected, execution=reported_by_source, review=unreviewed - categories: T06, T02 · tags: seedance, higgsfield, video generation, historical test, audio not reviewed, genre style test - updated: 2026-10-29T22:50:08.359Z - url: https://veyrul.com/experiments/exp_01M64VFKFHWH7WWC8W9B318CR4 A black stair with red veins: a man in a dark coat and a figure in a grey cloak, a red-haired man crouched with a splash of black water, a crouch over a grey bundle, a close of a red-spiky-haired pale man looking down, a close of a long dark-haired person, and two figures on the stair seen from behind. Task: Render a red-haired man and a woman climbing a drowning black stair with red veins as a wet-stroke test (newer clause), at 20 s. Outcome: succeeded 0.84 s: A black stair with red veins: a man in a dark coat and a figure in a grey cloak. 2.51 s: A red-haired man crouched, another figure on the stair. 4.18 s: A splash of black water. 5.85 s: The red-haired man crouched. 7.52 s: Crouched over a grey bundle. 9.20 s: Close: a red-spiky-haired pale man looking down, in black armour. 10.87 s: Same. 12.54 s: Close: a long dark-haired person looking down. 14.21 s: Same, looking toward the camera. 15.88 s: Same. 17.56 s: Two figures on the stair seen from behind. 19.23 s: Same. Intent vs result: The sampled frames hold the wide for five samples (about 8 s); the picture reads as a darker, painted set than the sibling run with the shorter prompt. 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. ```json { "inputs": [], "run_at": "2026-08-31T08:26:51Z", "metrics": [ { "name": "output_duration", "unit": "s", "value": 20.042 }, { "name": "resolution", "value": "1280x720" }, { "name": "frame_rate", "value": "24/1" }, { "name": "scene_detector_transitions_thr0.30", "value": 0 }, { "name": "black_intervals", "value": "none" } ], "procedure": "Seedance 2.5, text-only prompt (no linked inputs recorded in the job metadata), 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 test (newer clause)), 20 s, 16:9, audio requested, no seed set.
