I try to encode a video using bluray compat but I try ti set manually --mbtree to ensure that I use this option, but in the final video, if I use mediaInfo, I see that mbtree is 0, so it is not used.

So my doubt is if bluray compat is incompatible with mbtree or if exists another option that i would be the cause of this.

My script is the following:

x264 --crf 18.5 --level 4.1 --preset placebo --bluray-compat --b-pyramid strict --mbtree --deblock 0:0 --ipratio 1.1 --pbratio 1.1 --keyint 240 --min-keyint 24 --qpmin 0 --qpmax 35 --aq-mode 1 --aq-strength 1.0 --qcomp 1.0 --partitions all --direct auto --weightp 2 --psy-rd 1.0:0.25 --no-fast-pskip --no-dct-decimate --deadzone-inter 0 --deadzone-intra 0 --nr 0 --threads auto --fps 23.976 --output "myVideo.mkv" "j:\myVideo.m2ts"



Thanks.
Daimroc.

--qcomp controls mbtree strengths (from 0.0 to 1.0) and 1.0 basically means mbtree == off.

If you don't know your way around the options I suggest you stick to the examples and only change the preset and tuning (and 2pass to crf):

/edit:
I see that you are using mkv output - if you are not aiming for a Blu-Ray/AVCHD structure I would not recommend --bluray-compat and all that other stuff.

Yes, mkv output by definition isn't compatible with bluray (as in, usable to author a bluray disc).

You really shouldn't limit the QPs, or do any of that other stuff. Follow these settings and be done with it:
