Six-second continuous take from a peg-motion reference: the camera path and blocking transfer, but the ball changes from smooth grey to worn cream leather between 3.40 s and 4.15 s.

Task: One continuous low-angle take pushing from a bleacher-backed wide toward a player and a ball, following the peg video's path.

Outcome: partial

0.38 s: Wide, low grass-level camera; player in blue bib beside a smooth dark-grey ball in front of bleachers.
2.64 s: Heavy horizontal motion blur across the grass as the camera sweeps; the player stays small and distant.
3.40 s: Reframed foreground: legs in dark trousers beside the same dark-grey ball.
4.15 s: Ball is now a worn cream/white leather ball with seams and scuffs; a shoe pins it. Identity of the key prop changed within one continuous take.
5.66 s: Hold on the new ball and legs; the distant player remains in the same blue kit and position.

Intent vs result: Camera path and blocking follow the peg input (compared in an earlier review of the input video); the prop does not stay consistent. Earlier stills-only review had flagged the ball change as a hypothesis; denser sampling confirms it between the 3.40 s and 4.15 s samples.

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 8 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] Motion and geography transfer well from a peg video; small hero props are the first thing to drift. Re-state the prop in every beat or split the shot so the prop appears in one beat only.
