Abstract: The Image Interchange Framework (IIF), created by AMPAS with the goal of providing a unified post-production workflow, has seen increased interest in recent years. Central to the IIF is the RGB wide-gamut color space defined by the Academy Color Encoding Specification (ACES). For output device viewing, the ACES data must first be rendered through the Reference Rendering Transform (RRT) and the Output Device Transform (ODT). Recently a quasi-logarithmic 12 bit integer ACES encoding scheme was proposed, and we present initial results on the direct display of integer ACES content on a Dolby PRM-4200 monitor. Frames were delivered directly to the monitor across a 12 bit dual link SDI interface, and the decoding, as well as the RRT and device ODT were computed via 1D and 3D LUTs resident on the monitor. Several different LUT designs were considered, and the limitations of each including failure modes will be discussed.
