Abstract: In a control device for a motion picture camera that has a record button and a control circuit connected to the record button, the control circuit is configured to cause a start of a motion picture recording in response to a first actuation of the record button. In a normal recording mode, the control device causes a termination of the motion picture recording in response to a second actuation of the record button. In a tail slate mode, the control device, in contrast, only causes a termination of the motion picture recording when first a second actuation of the record button takes place and then a third actuation of the record button takes place.
