YouTube Channels with HDR Content
Here is a collection of YouTube Channels with some HDR Content that I have come across so far. Each of the following underlined bolded text is a clickable link...
HDR Launch Playlist
A collection of 4 videos that were produced for the launch of YouTube 4K HDR.
The HDR Channel
In addition to some of the stuff you may have already seen via the downloadable demo files there is some new stuff that is being added everyday such as a 12+ minute YouTube HDR video of the Netflix Original Series, Tears of Steel which is an open source movie created by the Blender Foundation.
created the HDR version starting from their 500 GB master! Sintel is next and that one has a 600GB+ master!! The host of this channel also maintains a list of all known HDR YouTube video available he is aware of here
Although there is some overlap with other channels, if you look under the Uploads section you will find a number of new SDR to HDR conversions. Many of these I have never seen before and I suspect the same goes for other guys based on the low view count for some. For example, I feel like I am revisiting Europe through the Samsung UHD 7 Wonders of the World Italy video and some of the other assorted travel videos available on this channel. For the gamers out there, this channel includes a pretty cool trailer of Rise of the Tomb Raiders available for the PS4 Pro. At least 20 of the videos on this site have view counts in the low hundreds!
There are only a few HDR videos on this channel so far but it does contain the Grays Peak video many guys have downloaded as a demo file back in the olden days before YouTube HDR.
: Some channels you might encounter such as a channel called "UHD/4K", which has some fine 4K videos, have taken the liberty of calling a number of files on their site real hdr when in fact none of the files I tested are HDR so be sure to check the banner as shown in the attached thumbnail before concluding a file is really HDR.
