An Engineering Approach to Consistent Images: Control of Video and Film Image Quality in TV Production

Engineers, video operators, colorists and producers, all share the goal of excellence in television image quality. This paper explores the reasons why some popular and widely used techniques to standardize video and film quality have met with mixed success. A practicable solution is proposed. — Previous efforts have, by and large, lacked the precision to ensure consistent high quality images, particularly in regard to tonal range and color. The new system under discussion, while providing production teams with infinite freedom for artistic expression, controls the technical aspects of image quality from camera set-up through the post production process. — Using familiar waveform monitoring techniques, the system is comprised of two elements: (a) Optical Signal Generators (OSGs) precision test targets, and (b) a unique portable illuminator. — The system, now in day-to-day use in network engineering and studio operations, can provide similar benefits to the production community. A major advantage of using this proven engineering tool through all stages of production is that engineers, operators and production personnel can now all speak a common language. — The system benefits film production and scanner/telecine setup. Ongoing tests with major film transfer houses are also discussed.
