Seedance 2.5 reference-anchored test: 20 s studio drummer with a red balloon on a snare
Dark studio: a drummer in a black tee, a red balloon on a snare head, stick close-ups, a burst balloon with water and ripples, a close face and a smiling end.
Task: A studio shoot of a drummer in the style of high-speed-camera footage.
Outcome: succeeded
0.84 s: Wide: a man in a black tee at a snare drum with a red balloon on the head, dark studio, rim light at left.
4.18 s: Close-up of the stick over the balloon.
5.85 s: Top-down: the stick presses into the balloon on the drumhead.
7.52 s: The balloon wraps around the stick.
9.20 s: Water appears around the balloon.
10.87 s: Close on the drummer's face, eyes closed, droplets in the air at right.
14.21 s: A red balloon fragment above the drum, a ripple across the head.
15.88 s: Fragment higher in the air.
17.56 s: Wide again: droplets like rain, a red remnant on the drum.
19.23 s: Drummer smiles, sticks crossed.
Intent vs result: The sampled frames show the balloon-and-stick beat and a ripple on the drumhead. Slow-motion timing cannot be judged from still frames.
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, 16:9, audio requested, no seed set. One of a run of tests on 9 August 2026 (UTC) that each pair the same kind of reference still with a different subject, genre and visual style. 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.",

"Sampled visual inspection from timestamped frames (contact sheets), not full real-time playback; motion smoothness, micro-timing and lip-sync are unrated.",

"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 single prop (the balloon) gives a clear start, middle and end across shots in the sampled frames.
