A motion picture apparatus is provided which comprises a rotary disc shutter having a shutter sector and actuated by an electric drive device. A claw mechanism is controlled by the electric drive device and provides for transport of a film. An electromagnetic solenoid provides for stopping the film in position. A plunger for the solenoid is provided for disengaging the claw transport mechanism after a frame transport phase upon generation of an appropriate signal. A position signal generator provides a shutter position signal depending on the position of the shutter sector and a marking signal generator provides a signal depending on the detection of a marking placed on the film. The position signal generator is connected to a first input of an AND gate and the marking signal generator is connected to a second input of the AND gate. The output of the AND gate is connected to the solenoid. The apparatus and a corresponding method provide for stopping a film without interference in proper position.
