Camera dropoutShare of frames from live episode cameras that are almost entirely one flat black or white value. A camera blank for a whole episode is counted as absent, shown underneath, not as a dropout. Method →
0
0 frames
BlurShare of camera frames inside an interval at least 0.5 s long where the image is much blurrier than that camera's typical frame. Method →
7.0%
50,539 frames
DarknessShare of camera frames inside an interval at least 0.5 s long where 60% or more of the pixels are near-black. Method →
<0.1%
50 frames
FreezeShare of camera frames inside an interval at least 1 s long where the video repeats the exact same image. Method →
0
0 frames
Duration mismatchShare of assessed episode-camera pairs whose metadata video length disagrees with the Parquet frame count by more than 1 frame. A hatched cell with * means only some pairs could be assessed (the small number shows how many); the rest are unknown, not clean. –* means none could be assessed. Method →

Flagged episodesEpisodes flagged by any episode check: actions that never change, a robot that barely moves, non-finite values, broken row indexes or timestamp gaps. The count is on top, its share of assessed episodes underneath. Method →
0
of 1,500 assessed episodes
Video offsets in this dataset are inconsistent, so video intervals can’t be assigned to episodes. Counts still cover every decoded frame.
