At least as of a couple of years ago, HDR support on YouTube has been pretty bad[1]. I know they've been working to improve things since, but I kind of don't blame people for walking away from that mess.

Thanks, will check out LTT's gripes, but I've been watching the following HDR channels forever and they look great:

I'm also glad that Rambalac is back as he quit a few months ago. I've recently also started uploading 4K60 HDR content to YouTube [1] and it takes up to one week more time for them to encode than the SDR version. You can include your own LUT instead of YouTube conversion which seems to help. Here's an article and LUT [2] + a video [3] with valuable info. They allowed me getting DJI Pocket 3 HLG recordings to HDR10.

Can´t recommend Rambalac enough - I have pretty much re-traced his steps multiple times during our Japan trip a couple times & it really helped with orientation. :)

Also some of the walks are really interesting & really gives you the context of various places in Japan. :)

The real issue is it's either HDR or good SDR, but not both at the same time
It’s still bad. Even as a totally amateur videographer making short clips of my holidays, YouTube is not good enough.

HDR processing takes months!

The SDR down conversion is “potato quality” even to my non-expert eyes, let alone a Hollywood colourist.

Etc…

Instead of YouTube's HDR->SDR conversion you are free to use your own conversion LUT with mkvmerge. As I posted above, here are some links for info:

- Workflow and a valuable LUT: https://www.wesleyknapp.com/blog/hdr

- Some DaVinci Resolve Settings to use on SDR monitors: https://youtu.be/4izJfgRtkZE (though I upload 4K60 HDR at 37.5Mbit) which is enough for me slow content.

This only allows a single LUT for the entire video. For comparison, Resolve will perform Dolby Vision tone mapping from HDR to SDR on a clip-by-clip basis.
HLG still not good enough?
