Abstract: The March of Time requires equipment of great portability and simplicity of operation, yet retaining good quality. By using Class B push-pull, variable-area recording, a complete noise-reduction sound system weighing fifty pounds was obtained. This single system was used in production of the feature picture The Ramparts We Watch. Problems arise from (1) recording on panchromatic negative, (2) lack of control over negative processing, (3) instability of recording unit caused by rough use of camera on which it is mounted, and (4) distortion due to lateral track shift. Means for overcoming these handicaps sufficiently have been found. Single system can be used without great sacrifice in quality, where time and space are factors.
