HDR på Youtube uppges få M1-Macar att krascha

High dynamic range (HDR) is a technology for the way luminance and color intensity are represented in videos and images. In contrast with the retroactively-named standard dynamic range (SDR), HDR allows the representation of brighter and more detailed highlights, darker and more detailed shadows, and a wider array of more intense colours. HDR video and its related technologies and standards are concerned with the capture, creation, encoding, decoding, containing, and reproduction of video with this wider dynamic range. HDR allows better exploiting the brightness, contrast, and color capabilities of HDR-compatible displays. It does not improve a display's intrinsic properties. Not all HDR displays have the same capabilities, and HDR content will thus look different depending on the display used.HDR10, HDR10+, Dolby Vision, and HLG are common standards that govern the hardware requirements, encodings (including content creation and playback), and distribution of HDR video.The HDR technology related to displays came about in 2014 first for video. It is now also available for still pictures.HDR technology is frequently confused with wide colour gamuts (WCG) and vice-versa. Some of the purported benefits of HDR, particularly in terms of colour range, are actually the result of a WCG. The dynamic range to which HDR refers is the range of luminance (perceived as brightness), not the range of the colour space, which is instead the domain of WCGs. As of 2021, HDR and WCGs are largely entwined, with HDR displays typically featuring a WCG. Nonetheless, HDR should not be taken to imply a WCG.
