Exercises videos

Hi, I started more videos about exercises. Unlike for the lectures I use a tablet. That makes the sound worse, but gives the opportunity to better scribble.

If you look at the page with videos, and click on some of those, you will see the video is sometimes "mirrored"., i.e., it unreadable.

The reason seems to be a feature of the vortex system, getting confused by some embedded meta information.

If you download the videos (instead of watching in a browser), it should work.

The meta information seems to come from the tablet, depending on how I place it (the "top" to the left or to the right, in landscape mode). It's difficult to figure out what is the right orientation, since the tablet looks the similar in all directions.
