The same state-conditioned video model fine-tuned twice on WildWorld part 1, once on all 3,434 episodes as released and once with 368 episodes removed, the 349 whose picture barely changes from one frame to the next and nineteen more that run under two minutes. Same eight WildBench axes, 200 test samples on each. The edited run scored 5.2 points higher.
A same-size random cut of 368 episodes scored 30.9%, inside the full arm's interval, so the gain is from which episodes were removed and not from removing episodes.
The axes that move are the ones about motion and state, Motion Smoothness and State Alignment first, which is where the removed footage was thinnest. Image Quality and Aesthetic Quality sit flat, because dropping quiet footage does not change how a single frame looks. The pooled lift clears zero, most single axes at 200 samples do not, and the chart says so.
Measured on the whole of part 1, all 3,434 episodes and all 13,740 files, read from the public file tree with no sampling. Every episode carries rgb.mp4, depth.mkv, state.csv and skeleton.npz and not one of the four is missing anywhere. state.csv and skeleton.npz are per-frame records, so byte size stands in for length, and the two agree, skeleton.npz holds between 984 and 1,400 bytes per frame across all 3,434 episodes and tracks state.csv at r = 0.9933. On that footing the release runs from a 12.3 second episode to a 46.1 minute one around an 8.9 minute median. The number that decides the cut is a different one, how many bytes the RGB encoder spends on each frame, which is what a frame costs when it differs from the one before it. 349 episodes sit under 4.54 Mbps against a 7.57 Mbps median at the same 720p and 30 fps, and 133 of them also fall in the lowest tenth of the corpus on the lossless depth stream, 3.7 times what chance would give. Nineteen more go because they run under two minutes on an otherwise normal motion budget, in a release whose own construction pipeline is described as removing short clips. Length on its own is not a defect and the rule never treats it as one, 67 of the 92 episodes under three minutes stay, 13 of the 14 sessions over half an hour stay, and the removed part has a median length of 8.3 minutes against 9.0 minutes for what is kept. Every number on this page comes from the public file tree, the episode files themselves sit behind the manual access gate, so no frame of the release is reproduced here.
