24-Frame and Multiple Frame-rate Post Systems and Equipment Design Considerations

With the growing interest in 24-frame high definition video production certain realities are becoming apparent. The first reality is the great difficulty in creating a flexible and affordable high definition production environment that possesses the user's required performance attributes. The second reality is that cost factors weigh heavily on design considerations for system designers as well as for equipment manufacturers. — Panasonic is approaching the 24-frame issue as part of a multiple-format solution for users who do a great deal of work with film-originated video. Electronic shooting can not match film's image performance and it's highly unlikely that technological developments in the near term will lead to an electronic system capable of displacing film's desirable attributes. Therefore, 24-frame video is more appropriately an element of the evolving high definition entertainment industry, not a solution in and of itself. Television equipment that is limited to 24-frame high definition functionality with separate equipment for 25, 30 or 60 frame video is not a viable economic picture for manufacturers or for cost-sensitive production of high definition programming. Panasonic believes that only multiple-use systems and production devices will lead to the widespread and long-term success of high definition television. — Implementation of multiple-image format and frame-rate systems and devices creates a new set of design challenges for image and control systems. Videotape continues to be the backbone of modern television production. This paper will address new system and performance criteria for the multiple-format mastering video recorder. Engineering considerations to be addressed include the need for multiple timecodes, transcoding timecodes, internal and external image format conversion requirements, remote control and system environments.
