Seedance 2.5 found-footage basement sequence with REC overlay on a black tail (20 s)
Handheld night basement exploration: stairs, shelf wall, chest freezer and a figure in the coal-room doorway; a red REC indicator appears only during the black tail from 18.1 s.
Task: Night found-footage: harsh on-camera light, grain, a basement with a stair at right, a shelf wall at left, a freezer ahead and a coal-room doorway.
Outcome: succeeded
0.63 s: Wooden stairs at upper left lit by harsh torch light; dark figure at the bottom of frame.
3.13 s: Torch glare washes the frame.
4.39 s: Shelves of jars and paint cans; a lit glass door.
6.90 s: Chest freezer with open lid at back, burlap hanging at left, coal-room doorway beyond.
13.17 s: A can falls to the floor near the shelves.
15.68 s: A pale upright figure becomes visible in the dark doorway.
18.13 s: Black frame with a red REC indicator at the top left; REC stays to 19.95 s.
Intent vs result: The REC overlay is not visible in the footage frames; it appears only with the black tail (18.04-20.0 s), as if the camera cuts out. Detector cuts at 0.04 and 18.04 s.
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.

}Evidence claims
- [sourced_fact] Timestamped observations above come from viewing 19 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] Layout continuity held (stairs, shelves, freezer, doorway). A viewfinder 'REC' flourish arrives with the cutaway, which makes the black tail read as a deliberate camera-off ending.
