YouTube is rolling out HDR support for videos that offer improved picture quality, higher contrast and more vibrant colors. The launch is limited, since HDR is still entering the mainstream, but the video-sharing site is preparing for its future. TechCrunch reports, “if you happen to own an HDR-enabled TV today, you can view HDR content on select YouTube channels going live with the enhanced content, like MysteryGuitarMan, Jacob + Katie Schwarz, and Abandon Visuals.” HDR videos can also be streamed “through Google’s newer Chromecast Ultra device, which debuted earlier this fall with 4K and HDR support.”
