Possible to merely "copy" an MKV's encoding settings?

Is it possible to merely "copy" an MKV's encoding settings found in its file information and use those same settings to rip from the original source again, resulting in an MKV of the same quality?


For example --


Person A and Person B both have the same exact bluray that they want to rip.

Person A rips the bluray into an MKV. Person B wants to mimic the quality of Person A's ripped MKV, so Person B looks in the A's MKV's info, finds the settings:

-Writing application (mkvmerge v5.8.0)
-Writing library (libebml v1.2.3 + libmatroska v1.3.0)
-Writing library (x264 core 125 r2200 999b753)
-Encoding settings (cabac=1 / ref=5 / deblock=1:-3:-3 / analyse=0x3:0x133 ...)
-Bitrate (5000Kbps)

And then seeks to use the same programs and settings on his rip of the bluray.


Would this work?

In other words, is the encoding information that's stored in A's MKV enough for someone to mimic themselves and get the same quality rip? Or is there some "magic" or "flourish" that wouldn't show up in an MKV's info, which could drastically vary the quality of the rip?

If the video was re-encoded with x264, which is very likely, you can easily find the encoding settings by running Mediainfo.  Once you have them, you can easily replicate them, either by using the command line or by recreating them in a GUI.  The latter might be more difficult as some GUIs might not present the user with certain settings.

The unknown element is processing.  If the video has been processed, it's not always easy to work out how and with what settings.

Assuming the video has not been processed and you have access to the same source, it is easy to make an MKV containing video of the same quality as someone else's.
