Abstract: A 16-mm motion picture camera for recording television programs at sound speed from a monitor receiving tube is described. Basic camera-design features include a 1200-foot magazine, which permits continuous recording of a half-hour program, separate synchronous-motor drives for the shutter and film-transport mechanisms, an 8-tooth sprocket pulldown actuated by an accelerated geneva star, an f/1.6, 2-inch focal length coated lens, and a 72-degree shutter. Other features include a“bloop” light to provide registration with the sound-film recorder, a film loop-loss indicator, and appropriate footage indicators. Some general operating characteristics of the camera are included along with a description of the pulldown system and the general problem of film steadiness. The last is particularly critical because of the high accelerations involved in the pulldown, in addition to the reaction of film to temperature and humidity changes.
