Hi, what are the exact meanings fo contains_cuts, always_visible and object_presence? Are the first two always the same per sequence while the last one might change from frame to frame? Thanks in advance.

Yes. The contains_cuts and always_visible fields are per-video and per-track attributes, respectively. They specify whether or not the video contains cuts and whether or not the object is always visible. These are simply used for analysis purposes.

The object_presence is per-object per-frame and specifies whether the object is present. This must be predicted by the model.
