Razor Blades to Computers.
Schneider, Arthur
Stages in developing editing equipment and processes for videotape are described. In 1956, when the first broadcast videotape recorders were installed, a splicing block, consisting of an aluminum block, steel ruler, and sharp razor blade, was used. Gradually, technicians developed more sophisticated methods. At present, two very advanced methods have been developed. The CMX 600 is a light pen editing system. In this technique, picture and sound information along with time code reference are all loaded segment by segment or scene by scene into magnetically coated spinning discs which rotate continuously at 1800 rpm. Scenes are accessed by scanning these discs with special pick-up heads. An offspring of the CMX is the Edipro 300, an on-line editing system in which one builds a master tape as he goes along. (JK)
