Properly implemented, HDR content remains back-compatible with today’s technology while making available metadata and picture information that will produce brighter, more dynamic, more colorful images on the displays of tomorrow. Instead of creating a standard based solely on the capabilities of existing displays, the video-standards bodies designed HDR to meet the capabilities of future displays as well. High Dynamic Range (HDR) was designed with the future in mind.

“These are the same patterns used regularly by the same people who produce your displays, players, and movie content.”

Like with the previous editions, the S&M UHD HDR Benchmark contains patterns suitable for the professional calibrator or serious amateur who wants a complete suite of test patterns usable with spectroradiometers and colorimeters. “ These patterns are tested by real industry professionals, multiple times over multiple iterations, before we put them on the disc,” said Spears. Every pattern we make goes through that same process, and is refined again and again to make it clearer, simpler, and more precise.” We rebuilt the color-space evaluation pattern from scratch, and put in one place everything an end-user or professional evaluator needs. “ The problems of artifacts caused by color conversion and video processing remain as relevant as ever for HDR and UHD, but HDR adds exciting new problems to all the old ones.

The disc includes new editions of some favorite patterns from the earlier editions, plus many new patterns exclusive to Spears & Munsil. “ We’ve created the very best single pattern for evaluating which color space to output from your UHD player or set-top box,” said Spears.
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”. 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. The Spears & Munsil UHD HDR Benchmark gives professionals and amateurs alike access to a wealth of test and demonstration materials to tell them what their displays are doing, identify weak links in their hardware and software, and dial in the optimal settings not only for their equipment, but for future equipment that hasn’t even been designed yet. The Spears & Munsil UHD HDR Benchmark adds even more features and patterns, and brings Spears & Munsil’s famous precision and attention to detail to the calibration and evaluation of UHD displays. The New York Times, and many leading industry publications have recommended previous versions of the Benchmark. “Stacey Spears and Don Munsil, acclaimed creators of the Spears & Munsil High Definition Benchmark series, are pleased to announce the release of the Spears & Munsil UHD HDR Benchmark.

With a little patience and basic understanding of how to use those old and some new video test signals, this 4K disc will provide the novice user with a user friendly tool to help obtain a near professional calibration. It provides an extensive range of picture alignment test signals updated to support the unique requirements of 4K HDR, its wide color gamut, specialized EOTF transfer curves and different peak white levels.
Just as their HD Benchmark discs became the goto HD calibration disc for many users, myself included, I am sure this UHD HDR Benchmark is slated to do the same for 4K calibration. Its been a long time coming but last week Spears & Munsil released their hotly anticipated professional 4K HDR video calibration disc.
