My source is testing the latest update with additional mods and if it checks out I'll add it to my server for everyone to use for HDR 10bit. I've used vapour synth too for 10bit as well with success. I'm messing with straxrip ffmpg prores 422 10bit for my YouTube channel and it's working great with my blackmagic 4k captures in lossless.
Hey thanks for your work! But I have a question. Could I be doing something wrong? Whenever I try to do it, the HDR tag works and it shows up as HDR on my TV, but my files are sooooo much smaller than scene encodes of the same video, with my settings as close as possible to their versions. I actually downscale mine to 1080p but noticed the average bitrate even with crf 14-15 was only about 3000kbps, which seems ridiculously low, so right now I'm encoding at 2160p and so far the average bitrate only seems to be 6000kbps, where as the scene release for the same video is about 11Mb/s - why is mine only half that? For the same source - 4k HDR bluray remux.

My encode is only about half-done, but staxrip is telling me the average bitrate so far is only 6450kbps. This can't be right. Again, I'm not encoding from an encode - I'm encoding from the 4k bluray remux so it's the same source. How could mine be only half the bitrate??
I have found a couple differences, but I can't imagine how these changes can cause my encode to by half the bitrates. The differences I found were scene had: bframes 4 instead of 8, rect enabled instead of none, me 3 instead of 2, zone-count 0 instead of 2, sar 1 instead of 0, chromaloc=1 instead of 0, chromaloc-top=2 / chromaloc-bottom=2 enabled (mine does not), scenecut-bias=0.05 instead of 0 (I actually tried to specify .05 in the settings but it shows up as 0 in mediainfo - it may be a nonstandard setting or maybe it won't show up correctly until the encode is finished). I also enabled zones for lower bitrates for the credits, but that's not going to cut my bitrates in half from the scene encode - not for just a few minutes of credits. To be honest, the final products that I've done when downscaling to 1080p look great on my 65inch TV, but I'm just amazed and confused how the bitrates can be soooo low compared to the scene releases (even when I try to do a full 2160p instead of 1080p encode).
EDIT: So apparently it's even possible to specify chromaloc and zone-count, it throws an error that is an unknown function. But I've changed the others and I'm trying again, but I'm not optimistic. I can't imagine how bframes, rect and me can drastically change bitrate.
