THE TALKIES 57 There are, of course, two film magazines on the camera, the top one to hold the unexposed film, and the lower one to hold the film which has been past the lenses. The film passes from the upper magazine down past the picture lenses first, and the picture is photographed on to it; in order to photograph the necessary series of still pictures, the film is held still for a fraction of a second before the next picture is taken; this happens about sixteen times a second for ordinary film work, and about twenty-four times a second when a Talkie is being made. The film has then to be led to that portion of the camera where the part of it which is going to take the sound-record is to pass before the recording light, which is, of course, controlled by the microphones. It will be obvious that the film cannot be allowed to have a jerky motion as it passes through the sound-camera because if it had the sound would be reproduced in a series of squawks instead of a continuous music or speech. A loop is therefore left between the picture "gate" and that portion of the camera which records the sound, and as the film travels round this loop it gradually loses its jerky motion and passes in front of the recording light smoothly and continuously.
