MOVIE-MAKING EQUIPMENT 73 Single System Sound Recording Sometimes, for convenience, it is useful to be able to record the sound on the film in the camera, and at the same time the picture is taken. This means that there is only one film to worry about and also cost is reduced by the elimination of the second film. The reader may be forgiven for asking, "Well, why not use that. It sounds perfect!" It does seem perfect, but, there are a few problems. To photo- graph scenes properly, a fairly fast film is required. This, of necessity, is of coarser grain than sound, positive film. On the other hand, sound recording calls for the use of very fine-grain film, and since there is always an adequate light source, the slowness of fine-grain film does not matter. At once there is conflict, and a compromise has to be made. But whatever is used, one of the two will suffer unless the light conditions are such that an exceedingly fine-grain picture film can be used. But even this will not be as fine grain or satisfactory as the sound positive normally used for sound recording. Another trouble also may appear; this is due to the short distance, in terms of frames, between the picture and the sound. This means that in order to filter out the intermittent motion caused by the passage through the picture gate a lot of effort has to be used. Even then, it is very difficult to eliminate completely all traces of flutter or wow from the film by the time it reaches the sound head. An- other trial is in editing: it is almost impossible not to lose some pic- ture or sound in this process. There are not many cameras on the market which cater to single system sound, but the best is the Auricon made by Berndt- Bach, Inc. The camera part of this combination has already been described; therefore, remarks will be confined to the sound record- ing section. The complete equipment was illustrated in Figure 3^L It is possible, if required, for the cameraman to speak into a micro- phone while he is operating the camera without any noise from the mechanism being picked up. This is not often necessary, for if the sound is not lip sync it is not usually important that a narration be recorded until the film has been edited. For television work where time is money and costs must be kept low, single system sound offers great possibilities to make synchronized films for low costs. If the
