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:

Addborders(0, 276, 0, 276)

For Vapoursynth using this line:

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))
