In connection with a comprehensive study of causes of variability in the color of television pictures, being conducted by an ad hoc committee (AHCCTS) of a joint industry committee (JCIC), a subcommittee has been investigating the contribution of telecine equipment and practices to the problem. The investigation has included detailed examination by subcommittee members of particular telecine operations and the preparation of videotape transfers from a common motion-picture film print at several telecine installations. In addition, a questionnaire was sent to broadcasters to obtain information on equipment in use, operating procedures, and attitudes toward the telecine operation. — This paper reports the results of this work to date. The conclusion is drawn that the telecine operation is a significant source of television picture variation, independent of and adding directly to the variation usually attributed to the film input itself.
