The disc includes new editions of some favorite patterns from the earlier editions, plus many new patterns exclusive to Spears & Munsil. In a few cases we’ve had to create our own format, because no existing file format could represent the pattern we needed to create.” If a pattern needs to be generated directly in a very specific color space and data format, we generate it in that color space and format we’re not limited to what you can do with off-the-shelf graphics software. “We build every pattern using our own tools, written from scratch in C++. “There really isn’t any other way to make patterns that we can stand behind,” said co-creator Don Munsil. Like the previous discs, the Spears & Munsil UHD HDR Benchmark uses patterns created from scratch using Spears & Munsil’s own in-house software. “ We believe this disc completely changes the game for test and evaluation discs, by making use of all of the features and range that HDR and wide-gamut standards can offer.” Almost every pattern is encoded in multiple versions, with metadata and peak levels adjusted for a wide variety of HDR display technologies. “ Every pattern has been rethought with High Dynamic Range and UltraHD in mind,” said co-creator Stacey Spears.
