Vimeo has announced that from now on HDR will use both the HEVC/H. 265 codec and 10-bit Rec. 2020 color, wide color gamut (WDC) and 8K videos. HDR video can be uploaded using existing integration with Adobe Premiere Pro, Apple Final Cut Pro X and Dropbox, as well as the dedicated Vimeo upload page.
For the correct playback of HDR videos, the display used in each case must also support HDR10 - but an SDR version of the video will also be created for displays that do not. For example, HDR playback is supported on Apple iPhone X, iPad Pro and Apple TV 4K, but not on Apple's desktop systems. Playback on Android and Google's Chromecast Ultra are not yet supported, but soon. HDR videos are marked with an "HDR"badge in the Vimeo player and the respective Vimeo website.
Vimeo now also supports 5K, 6K and 8K videos and compresses videos on the H. 264 codec as well as HEVC/H. 265. HDR will also be supported by VP9 codec in the future.
However, YouTube was once again a pioneer here and supported HDR for about 1 year and 8K since 2015.
