An Automatic Editing System, Using a Minicomputer, Scanning of the Color Negative and Broadcasting from a Videotape Transfer

Toshinori Miura, Hiroshi Tanimura

Among the many efforts now being made to improve the picture quality in color television using film as a source, one of the most promising approaches is scanning directly the color negative and broadcasting an edited videotape from the negative, instead of the usual positive print on film. This approach results in improved gradation, color fidelity, steadiness and resolution. In addition to these advantages, this method makes unnecessary the time-consuming task of negative matching or conformation. A sophisticated system has been developed which simplifies the editing process and can reduce to at least 25% the time and manpower customarily required for production of a finished program. The work is automated by using self-threading random-access film-to-tape transfer equipment, a remote-controlled quadruplex VTR and a minicomputer. Other features of the system include a unique electronic color-timing system and a newly developed scanning-projector which can be loaded with ten 1,200-ft (366-m) reels of 16mm film in simultaneous storage.
