The disc features test material and calibration patterns to help home theater enthusiasts evaluate displays and players and adjust their home theater systems to get the best possible picture. The disc’s Demonstration Material section features a great montage of images from the beautiful Pacific Northwest. You’re treated to some beautiful coastal scenery from the Astoria, Oregon, area and some extensive coverage of the Seattle area as well.The montage footage was filmed on the new RED ONE 4K HD camera. This makes this the only Blu-ray Disc that has test material captured native at 4K (downconverted, of course, to 1920 by 1080 for the Blu-ray transfer). This makes it a great piece for video demonstrations and showing off your home theater.
