I don't believe staxrip supports any encoders that can encode HEVC with UHD Blu-ray compatibility. It might be possible by tweaking a lot of x265 parameters, but I don't recall hearing of anyone actually even trying that, let alone succeeding.

I'm asking around about what encoders people actually use for UHD-BD authority.

You must reencode the movie, you cannot "add" the borders on Top/bottom on thy fly.
If u using avisynth/vapoursynth, it is very simple:

Adding in your Avisynth Script this line:


Code:
Addborders(0, 276, 0, 276)
For Vapoursynth using this line:

Code:
clip = core.std.AddBorders(clip = clip, left = 0, right = 0, top = 276, bottom = 276)
Ok, thats the first part, now the second Part. You must reencode the video with UHD acomplished settings. I use this Settings for 4K UHD videos. You must check the file with MediaInfo if u have the BT2020 or the P3D65 colorrange. Also edit in the lines the correct settings for the HDR output. (--max-cll "1000,400" and L(10000000,1))

BT2020 :

Code:
--crf 16 --preset veryslow --limit-refs 0 --max-merge 5 --pmode --pme --profile main10 --colorprim bt2020 --colormatrix bt2020nc --transfer smpte2084 --range limited --level-idc 5.1 --rd 6 --rd-refine --rdoq-level 1 --psy-rdoq 4 --psy-rd 2 --tu-intra 1 --tu-inter 1 --limit-tu 0 --sar 1 --aq-mode 1 --qcomp 0.7 --ref 4 --bframes 4 --selective-sao 0 --rskip 0 --no-open-gop --no-info --no-sao --no-rect --no-amp --hme-search umh,umh,star --hme --repeat-headers --aud --uhd-bd --min-keyint 1 --keyint 24 --hrd --vbv-bufsize 80000 --vbv-maxrate 100000 --hdr --output-depth 10 --hdr-opt --max-cll "1000,400" --master-display "G(8500,39850)B(6550,2300)R(35400,14600)WP(15635,16450)L(10000000,1)"
P3-D65:

Code:
--crf 16 --preset veryslow --limit-refs 0 --max-merge 5 --pmode --pme --profile main10 --colorprim bt2020 --colormatrix bt2020nc --transfer smpte2084 --range limited --level-idc 5.1 --rd 6 --rd-refine --rdoq-level 1 --psy-rdoq 4 --psy-rd 2 --tu-intra 1 --tu-inter 1 --limit-tu 0 --sar 1 --aq-mode 1 --qcomp 0.7 --ref 4 --bframes 4 --selective-sao 0 --rskip 0 --no-open-gop --no-info --no-sao --no-rect --no-amp --hme-search umh,umh,star --hme --repeat-headers --aud --uhd-bd --min-keyint 1 --keyint 24 --hrd --vbv-bufsize 80000 --vbv-maxrate 100000 --hdr --output-depth 10 --hdr-opt --max-cll "1000,400" --master-display "G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)"
