: This is a large-scale dataset created by DeepMind for human action recognition. "vid_458" would represent a short clip of a specific human activity (e.g., "playing guitar" or "shaking hands"). You can find more details on the Kinetics-700 page.

In the context of an "informative feature," this usually refers to the or extracted descriptors (like motion vectors or optical flow) that help an AI understand what is happening in that specific video clip.

Are you working with a (like Kinetics or YouTube-8M)?

: These are older, foundational datasets used for action classification. In these sets, files are often renamed during preprocessing to simple numeric strings like "vid_458.mp4" for easier programmatic access.
