I think than CRF ([-12-51, default 23.0] Constant Ratefactor. While qp targets a certain quantizer, and bitrate targets a certain filesize, crf targets a certain 'quality'.) is equivalent to rigaya's NVEncC:

Quote:
Constant quality mode can be used by "--vbrhq 0 --vbr-quality <float>".

--vbr-quality <float>

Set target quality when using VBR mode. (0.0-51.0, 0 = automatic)
Maybe you can do some test replacing the encoder in the "__ENCODE_3D.cmd"
For instance if you have:
Quote:
"C:\Portable\Util\BD3D2MK3D\toolset\x264_x64.exe" --output-depth 8 ^
--crf 23 --preset medium ^
--sar 1:1 --range tv --colormatrix bt709 ^
--frame-packing 3 --qpfile chapters_3D.qpfile --frames 158712 --fps 24000/1001 ^
--output "00009_3D.264" "__ENCODE_3D_MOVIE.avs"
You can change it to
Quote:
"C:\Portable\Util\BD3D2MK3D\toolset\NVEncC.exe" --output-depth 8 ^
--vbrhq 0 --vbr-quality 23 --bframes 3 --ref 3 --bref-mode each --lookahead 32 --weightp --aq --direct spatial ^
--sar 1:1 --colormatrix bt709 ^
--chapter chapters_3D_delay.ogm.txt --key-on-chapter --fps 24000/1001 ^
-i "__ENCODE_3D_MOVIE.avs" -o "00009_3D.264"
Replacing the path and filenames in bold by yours and the x264 parameters with NVEncC parameters:

--crf 23 maybe can be replaced with --vbrhq 0 --vbr-quality 23
--preset medium is, more or less, equivalent to --bframes 3 --ref 3 --bref-mode each --lookahead 32 --weightp --aq --direct spatial
--range tv seems the default with --fullrange can be equivalent to --range pc
--frame-packing 3 I don't kown the equivalence
--qpfile chapters_3D.qpfile can be replaced by --chapter chapters_3D_delay.ogm.txt --key-on-chapter
--frames 158712 all frames are always the default for NVEncC or x264/x265
