Abstract: As more experience is gained producing programs for dual-use, in both 16 times 9 and 4 times 3 aspect-ratio environments, trends are emerging that define the limits of acceptable conversion from the requirement to image and edit separately. This paper will explore real-world experiences with down conversion and up conversion used in actual programs, and offer some tentative solutions to the challenges presented by the often conflicting requirements imposed by the artistic integrity of each standard and the financial realities of the production business. The general conclusion of the paper is that the ability to produce simultaneous program outputs in both aspect ratios is program-type limited, and is also dependent on the primary delivery aspect ratio with respect to program revenue. Technical quality of real-world converters will are explored, and recommendations made regarding areas for improved performance.
