H01 viewed 8-16 timestamped frames of every output and of five of the peg videos. This is a retrospective observation set, not a benchmark and not validation of any current pipeline.\n\nWhat transferred: (1) camera path - the rising reveal at a table-tennis court (13.2 s of 15 s), the hallway move with the same wall sign, and the high ledge view all follow the peg video; (2) foreground occluders - a large grey foreground mass became a real person's arm and shoulder in a fence shot; (3) identity and wardrobe across 20 s of the hallway take.\n\nWhat drifted: (1) a hero prop - a ball changed from smooth grey to worn cream leather between 3.40 and 4.15 s in a shot with no cut visible in the sampled frames; (2) background characters left the table-tennis frame as the camera rose; (3) a close frisbee shot ended on a railing vault with lawn geography that the peg video did not show; (4) a wide ledge vantage kept composition but left the subject too small to judge action.\n\nRetiming: the output durations (6.0, 10.0, 15.0 and 20.0 s) differ from the peg videos (6.6, 9.0, 12.7, 14.8 and 19.3 s), so beats shift by up to several seconds; compare beats, not clock times.\n\nPractical reading (inference from these sampled takes, untested elsewhere): use a peg video for camera and geography; restate the hero prop in every beat (an untested precaution inferred from the drift above); keep key subjects large enough in the peg framing to judge their action; expect late-shot divergence in long takes.
