After uploading a video, you can change its properties any time after that.

By the mediawall view, you can see all of your uploaded videos.

Within the actions menu you can change the order of the media files ("Medienreihenfolge ändern"), view a list of all of your uploads ("Meine Uploads") and copy videos in other courses ("Medien kopieren"). Within the "views menu" you can change the view between list and mediawall view. Additionally, you can change the view with the shortcut buttons in the top right corner. Furthermore, you can filter and search within your uploaded videos.
