A Crystal-Controlled Time Code for Synchronizing Film and Audiotape — A Translation

At the present time, methods of film production with double-system sound synchronization using time-code identification on both the picture film and picture sound tape as well as the technical feasibility of such a system are being studied by many organizations engaged in television programing and equipment manufacture. In this paper an example of a complete crystal-controlled time-marking system, from film shooting to editing, is described.
