Workshop video is a video that belongs to a particular workshop. In this case, we're looking into ATM1 that was given in Munich, November 2025 workshop.

On the left, we have some basic information:

There's a title, teacher, or student involved
The particular workshop he belongs to

On the right, we have Mark has watched, download, copy to my library, and enable subtitles buttons.

Mark has watched will mark this video as watched, and it's a little reminder to yourself that you have actually seen this video

Download will prompt a dialog and ask you to download the video. A small fee might be required

Copy to My Library will copy this particular workshop video to your own personal library

Enable subtitles should be self-explanatory
