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
