Seedance 2.5 grey-peg test: table-tennis rally, bystander walks away across the lawn (15 s)
Second iteration of the table-tennis scene: the bystander stays in view and walks off across the lawn while the camera rises, unlike the earlier take where she leaves early.
Task: Over-the-shoulder view of a rally, a bystander, then a rising camera reveal of the table.
Outcome: succeeded
0.63 s: Foreground boy in white tee at left; girl in grey tee and player in blue cap behind a blue table.
3.14 s: Player in grey tank extends a hand toward the girl.
5.64 s: Player holds a red paddle low; the girl stands still.
8.15 s: Player raises the paddle; the girl is unchanged.
9.41 s: Girl turns and walks away toward the lawn; the player leans back.
10.66 s: Camera begins to rise; the girl is a small figure at the back.
13.17 s: High view of the whole blue table; boy's head at frame left with glasses visible at 11.91 s.
14.42 s: Girl is a distant figure at the top edge of the lawn.
Intent vs result: Same shot design as 2b1b7f00 (earlier). There the bystander has left the sampled frames by 6.90 s; here she is visible until the end as a small figure. Peg video for this variant not separately viewed.
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 text-and-reference video generation with a grey-peg motion video (a rendered blocking pre-visualisation that fixes camera path and positions), several approved scene stills and per-character face/front/back reference photos, plus a long structured prompt (look statement, reference-use rules, cast, camera, ordered choreography, continuity, sound). Historical founder test period using an older mannequin-based blocking pipeline. Sampled inspection: 12 timestamped frames from 0.63 s to 14.42 s of a 15.05 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.",

"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."

}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] Background-character persistence differs between iterations of the same setup; pick the take whose blocking fits the edit.
