YouTube announced that it now supports high dynamic range (HDR) video, offering higher contrast and a more vibrant range of colours. Simply put, HDR unlocks the most spectacular image quality we've ever streamed, said the company in a blog post. YouTube videos in HDR can only be viewed on supported devices, such as HDR TVs with the new Chromecast Ultra, and soon on all 2016 Samsung SUHD and UHD TVs. However, the only smartphone on the market with official HDR capability was the now unavailable Galaxy Note 7. The company added that it will work with partners to enable streaming of the HDR version of videos as more compatible devices become available. Creators can already upload HDR videos to YouTube as simply as SDR videos and the companys YouTube Spaces in Los Angeles and New York have been outfitted with all the gear needed to produce HDR content.
