A Disc/Tape System for Time-Lapse Video

Akira Yonekura

This system has recently been developed by NHK for time-lapse, or frame-by-frame video recording at desired intervals. Generally, frame-by-frame recording was applied in the field of film cameras as a technique to visualize long-period phenomena in a short time by means of time compression. Such phenomena include moving clouds, growing plants, opening flowers, cell division as observed through a microscope, and moving people and cars at a crossing. In the past, we performed frame-by-frame video recording using multiple magnetic disc memories. This scheme, however, had shortcomings in that the recording time was short and that complicated operations and much time were needed to produce TV programs.
