The encoded video is x265 10 bit which i think it has very good quality, clean and sharp
I'm trying to guess the x265 parameters of this encoded video
This encoded video was claimed not used avisynth or any filter
Any one can help me to guess what x265 parameters are used ?

(This parameters seem close but not perfect : --preset medium --crf 22 --no-sao --no-rskip --psy-rd 0 --aq-mode 2)

If you are playing it with MPC have yo tried to go to "propierties->mediainfo" to view if the "Encoding settings" are present. Fron that you can derive the parameters.

There is nothing in the encoding setting, that is one of the reason i tried to guess the encoding parameters

It seems I violate rule number 6
But I believe it is not true
Source video is one minute cut from my own bluray disc
And yes, one minute cut encoded video is from some "illegally encoder website"

The main focus here is not to "illegally share" or "violate the copyrighted content" but to analyze how could they be able to encode video into "very good quality, clean & sharp" x265/HEVC which everyone in this forum dreamed of

So I hope you might consider to allow this thread and unremoved my attached content links
Thanks

Why not just use MediaInfo to extract the entire x265 parameter string of the encode you like, and post that instead?

Like i said earlier there is nothing inside mediainfo parameter string
It seems encoder delete the parameter string on purpose

From memory, QSV HEVC doesn't write any encoding settings into the output's header, so you might not even be looking at an x265 encode at all.

It is easy to delete encoding setting parameters by using some hex editor, doesn't it ?

Posting a short excerpt from your own bluray disc is okay. However:
