New Video Recording Camera

The camera described has been designed specifically for video recording purposes, and therefore differs in many respects from the usual conception of a 16-mm camera. To accomplish intermittent film pulldown within the short space of time available, a multiple skip claw movement is utilized. The usual mechanical shutter is eliminated, but a device is incorporated to actuate an electronic shutter, which at the same time provides for the transition from 30-frames/sec television to 24-frames/sec film speed. In order to obtain the necessary film stability at the aperture, and to eliminate any tendency to scuff or wear off film emulsion at this point, a vacuum-operated film gate is utilized, which permits the camera to be operated for rather long uninterrupted periods of time. Provision is made within the camera for the simultaneous recording of sound, at standard spacing for correct sound synchronization.
