$\text{Learning videos in mp4 and ogv format}$

All learning videos are in German. They will not be translated in the future for effort reasons. Sorry!
After clicking on the desired video, a WIKI description page appears with a short summary and user interface.
Each video part can be started by a single click and stopped by another click.
The playback speed of videos can be changed:

(1) Firefox offers a corresponding submenu after a right click on the video field.
(2) For Google Chrome, for example, you can install the plugin "Video Speed Controller".
