Requisite Editing Equipment The actual mechanical features involved in the editing of sound pictures are relatively simple. They involve the use of the synchronizing machine, the Moviola, the splicer and the rewind. All of these devices are easy to operate and require only a minimum amount of experience to attain more or less perfection in their handling. The synchronizing of film by edge numbers has been explained previously. In addition, each editor is supplied with a synchronizing machine, the purpose of which is to enable him to keep his film in synchronization as he handles it. This device can best be described as a machine which carries anywhere from two to four sets of sprockets. The editor, while handling his film, places both the sound track and the pictures film over these sprockets, keeping the film in synchronization at all times while he is passing it from one reel to another during its handling. Should the film by any chance slip over the sprockets, the editor has the edge numbers by which to guide himself, thus avoiding the necessity of going back to the original start mark in order to check the sound track with the action. Most editors, however, do not use the synchronizing machine much but prefer the Moviola (film viewing and checking device). The practice is to place the sound track underneath the action, both passing over the same sprocket wheel. Inasmuch as the greater part of the sound film is clear, the light passes through and the cutter is able to handle both films without interfering with his observation of the picture. Experienced editors require the "syncing" machine mostly for lining up sound effect and musical tracks after the picture has been cut, enabling them to run the action on one set of sprockets, the dialog on the second, the sound effects on the third, and musical or other background noises on the fourth set. In this manner, the editor can run all of his film through the synchronizing machine at one time, matching-in everything in the one operation. There are two different type patches used in the cutting room, — one which covers the full sprocket and the other covering only the half sprocket. At Universal we find the half sprocket most Noris Carbons CUT COST AND IMPROVE PROJECTION EFFICIENCY SONOLVX Lamps average 27^ hours, A test made under actual projection room operating conditions ^NERBRO&THEj^ES STANLEY.MARK STRAND CORP.
