ABSTRACT Cinematograph-sound equipment where the sound from successive scenes is recorded on a magnetic tape travelling in synchronism with the picture film. To avoid accumulative differences with successive scenes between the length of the exposed film and the length of the recorded tape due to different over-run of the tape compared with the film, a device is interposed between the camera-switch and the recorder drive control which delays start of the recorder drive control in response to operation of the camera switch.
