New Systems for Handling Picture-Synchronous Sound
Newly developed equipment and methods for recording and reproducing picture-synchronous sound in film and TV studios have led to partial automation of studio work. Remote control is provided for all studio units. An example is Multicord, a magnetic film recorder-reproducer which makes possible fast rewinding in both directions without unthreading. Another useful device is Rotosyn, a system that synchronizes the speed of film transport mechanisms. In a new version, with a pulse generator, Rotosyn can be used with both double-system recordings and video-tape recording. Use of new systems and equipments affects final sound mixing in various ways. With yet another method, all points on the film at which a sound event should start or finish are marked by magnetic pulses on a programed magnetic film running on a special editing table beside the (picture) film. All films are then wound back, and mixing is done at a normal film speed.
