The production of motion-picture special effects can be a costly and time-consuming step in the production of motion-picture films. Although several electronic video systems have been proposed and demonstrated for use in special-effects generation, these lower-resolution video systems, including HDTV, do not operate transparently between film input and film output. They introduce a number of disturbing image artifacts to the final film element. This article defines the system requirements for a high-resolution digital image manipulation system that can be used to produce high-quality motion-picture special effects.
