ABSTRACT:
Process for making an improved duplicate negative from an original color motion picture negative by using optical color filters with flying spot scanning of the original negative to generate tri-color separation analog video signals. These signals are transmitted through active and/or passive electronic filters, at which stage the signals may be optionally modified. The signals are used to create images on a black and white cathode ray tube. A lens projects these images through optical color filters to create a latent image in each of the three emulsion layers of a color sensitive motion picture film. This process is repeated for each frame of the original negative, after which the exposed film is developed in the conventional way, resulting in a duplicate negative, suitable for use for release printing.
