Media are grouped into per-movie subfolders (<movie_id>/), where movie_id is the prefix of clip_id. A clip's files are therefore at <split>/video/<movie_id>/<clip_id>.mp4 and <split>/audio/<movie_id>/<clip_id>.wav.

One row per movie (movie_id 0…1811, ascending). Clip-level info is recoverable from splits/{train,test}.txt and the clip_id prefix (<movie_id>_<clip_idx>_<start>_<end>).

column	description
movie_id	dense movie index, 0…1811 (matches the clip_id prefix)
