A method for monitoring set parameters of a motion-picture camera is provided. Film images, which are extracted from a recording beam path of the motion-picture camera and which are converted into digital assist signals by an optoelectronic transducer are arranged in an assist beam path of the motion-picture camera. Digital assist signals are output to a processing unit with an image frequency matching the image recording frequency of the motion-picture camera or with an assist image frequency, to which processing unit recording, control and/or status signals of the motion-picture camera or of devices connected to the motion-picture camera are additionally fed as metadata. The processing unit analyzes digital assist images composed of the digital assist signals and outputs digital output data and control signals to control modules of the motion-picture camera and/or to a network, and/or as analog or digital video signals to a monitor connected to the processing unit.
