How to get videos for this work

• The Kinetics51 dataset is collected from YouTube, and the video name is also the ID of the YouTube link to the corresponding video.
• Example:
  • With video name 4jmv1XpnR90 above, the link to the video would be https://www.youtube.com/watch?v=4jmv1XpnR90. Similiar for other videos, concatenate the prefix https://youtube.com/watch?v= with video name to get the video link.
  • Video can be downloaded using open-source software (such as youtube-dl).
