+## Split: train
 
-Each record contains:
-- `video_name`: Original video filename
-- `video_path`: Relative path to video file (e.g., `videos/video.mp4`)
-- `frames`: Sequence of extracted video frames
-- `optical_flows`: Sequence of optical flow visualizations
-- `question`: Binary question about camera motion
-- `label`: Answer ("Yes" or "No")
