Quote:
--hevc-aq
Enable adaptive quantization It scales the quantization step size according to the spatial activity of one coding unit relative to frame average spatial activity. This AQ method utilizes the minimum variance of sub-unit in each coding unit to represent the spatial complexity of the coding unit.

-> 'hevc-aq'
so it's an issue with 'minimize command line'.
so looking at command line before setting psy-rd to zero:
Code:
x265 --input - --output-depth 10 --y4m --profile main10 --limit-modes --no-early-skip --no-open-gop --opt-ref-list-length-pps --crf 18.00 --opt-qp-pps --cbqpoffs -2 --crqpoffs -2 --qpfile GENERATED_QP_FILE --limit-refs 0 --ssim-rd --psy-rd 2.50 --rdoq-level 2 --psy-rdoq 10.00 --aq-mode 0 --hevc-aq --no-cutree --deblock=-1:-1 --limit-sao --no-repeat-headers --range limited --colormatrix unknown --output OUTPUTFILE
and with psy-rd to 0:
Code:
x265 --tune psnr --input - --output-depth 10 --y4m --profile main10 --limit-modes --no-early-skip --no-open-gop --opt-ref-list-length-pps --crf 18.00 --opt-qp-pps --cbqpoffs -2 --crqpoffs -2 --qpfile GENERATED_QP_FILE --limit-refs 0 --ssim-rd --rdoq-level 2 --psy-rdoq 10.00 --hevc-aq --no-cutree --deblock=-1:-1 --limit-sao --no-repeat-headers --range limited --colormatrix unknown --output OUTPUTFILE
before: --psy-rd 2.50 --aq-mode 0 --hevc-aq
after: --tune psnr -hevc-aq
checking tune psnr:
Code:
if (!strcmp(tune, "psnr"))
{
param->rc.aqStrength = 0.0;
param->psyRd = 0.0;
param->psyRdoq = 0.0;
}
see:
https://bitbucket.org/multicoreware/...mmon/param.cpp (line 566-571)
so: "--aq-strength 0 --psy-rd 0 --psy-rdoq 0"
since "--aq-strength 0" should be the same as "--aq-mode 0".
now looking again at before and after:
before: --psy-rd 2.50 --aq-mode 0 --hevc-aq
after: --tune psnr --hevc-aq = --aq-mode 0 --psy-rd 0 --psy-rdoq 0 --hevc-aq
since after also has '--psy-rdoq 10.00'
after = --aq-mode 0 --psy-rd 0 --psy-rdoq 10.00 --hevc-aq
-> don't see where Hybrid is making a mistake.
those command lines should be identical unless '--tune psnr' has other side effect that I don't know about.
