Abstract
Abstract A system to provide for the production of standard motion picture color film from a color video signal or color information composed of color components. The color video signal is decoded into its separate green, red, and blue components which components form a repeating color group. Each repeating color group includes individual colors from a single color field through the use of delay. The delay of the individual colors may be in time and with a recording of the repeating color group by the use of a single gun continuous film motion electron beam recorder on a black and white separation master. The delay of the individual colors may be in space and with the recording on the black and white separation master accomplished through the use of a three gun continuous film motion electron beam recorder. The color video signal occurs at 60 fields per second (50 fields per second in particu-ar locals) but the black and white separation master is recorded at 72 frames per second (75 fields per second in the particular locals) so as to provide for a conversion from the 60 or 50 field per second video signal to a 24 frame per second color film. The color film is made from the separation master by exposing each frame of the color film using appropriate color filters in sequence to three frames on the black and white separation master representing the green, red, and blue separation images.
