Abstract

See full text

To record motion picture film scenes, for example recorded at 24 frames per second, a television recording medium, such as magnetic tape, in accordance with the NTSC standard of 30 frames--60 fields--per second, a sequence of pulses (FIG. 1: graph c) are generated, for example in a motion picture film scanner (3), which pulses have a frequency which is characteristic for the scanning repetion frequency at any film frame repetition rate--for exaple 24 frames per second; a motion picture film scanner (3) and a video recorder (5) are jointly controlled by the central process computer and controller to operate the video scanner to scan the film at the time when a selected frame of the film is before the scanner and, simultaneously and based on a sequence of generated pulses, controlling recording of the film on the record medium by the recording apparatus. A transfer switch may be used, connected to a monitor (11), to selectively display either the scanned scene or the recorded scene.
