Seedance 2.5 reference-anchored test: 20 s woman gathering greens by a mountain stream, framed by a round vignette
A round vignette over a sunrise river, hands sorting leafy stalks in a basket, a blue damselfly, a profile close-up, crossing the stream on stones and a village on the bank.
Task: A woman in a cream linen work dress with long black hair gathering greens by a mountain stream.
Outcome: succeeded
0.84 s: A circular vignette showing a sunrise river valley, a figure at the water.
2.51 s: The vignette widens.
4.18 s: Hands sort green stalks in a woven basket.
7.52 s: Hands on the rim of the basket.
9.20 s: A blue damselfly on the basket, a woman's profile beyond.
12.54 s: She crosses the stream on stepping stones, the basket on her back.
14.21 s: Bare feet on stones.
15.88 s: She bends on the bank, a village behind.
17.56 s: She stands, smoke rising from rooftops.
19.23 s: Same.
Intent vs result: The sampled frames use a vignette opening and a clear sequence of tasks; the village and the stream stay consistent.
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) that asks for a large-format anamorphic-cinema look, 20 s, 16:9, audio requested, no seed set. One of a run of tests on 10-11 August 2026 (UTC) that each pair the same kind of reference still with a different subject and mood. 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.",

"Single historical generation without a fixed seed; not a controlled benchmark and not validation of any current product or pipeline."

}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 small living detail (the damselfly) adds a believable beat in the sampled frames.
