If lecture videos are to be produced for download or as livestream with good quality, the estab-lishment of a video studio is inevitable. The set-up of a simple studio in a converted seminar room is described. Green screen technology is used. This makes it possible to place the speaker in front of his digitally generated content and let him act as if he was in front of a classical black-board. Experiences with the installation and operation of the studio are presented and conclu-sions are drawn after approximately 100 hours produced lessons.
