Ultra HD Blu-ray is the latest iteration of Blu-ray disc technology and is rapidly being adopted by film makers and multimedia content creators. The format delivers unmatched 4K content, offering not only a significantly larger 3840x2160 resolution, but also a greatly expanded color range, provision of both high dynamic range (HDR) and high-frame rate (up to 60fps) content, and support for the latest object-based immersive sound formats.

High Dynamic Range (HDR)

High Dynamic Range, commonly referred to as HDR, is a popular style of still photography that significantly reduces shadows and highlights in pictures. When applied to moving images, this can have an outstanding impact on the level of detail and realism of what is displayed.

Ultra HD Blu-ray supports HDR video, meaning that when paired with an HDR-capable TV viewers can enjoy truer-to-life picture color. This is thanks to the capacity of Ultra HD Blu-ray discs to store more information about each individual pixel, and the ability to transmit that amount of data to UHD TVs.

In addition, Ultra HD Blu-ray discs are able to transmit content that is mastered at up-to 10,000 nits, which results in brighter, less faded pictures when viewed on HDR capable TVs. Standard Dynamic Range (SDR) TVs are capable of displaying 100 – 300 nits, while modern HDR TVs output 1000 nits or above, meaning pictures that are 4-10 times brighter and more detailed. At the time of writing, no TVs are capable of generating 10,000 nits output, however with the rapid advances in technology it surely is only a matter of time before they become commonplace in the consumer market.
