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

post #1 of 7
Thread Starter 
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?

Typically, a rip is a direct lossless copy of the movie on the disc. There should be no quality differences.
The only times you see quality differences is when you re-compress the video to save space. Rippers like MakeMKV only does lossless rip. I know some programs like Clone BD will re-compress the video to fit certain storage space.
In the case of re-compressed video, MKV metadata alone if not enough to tell what the encoding parameters are. Far from it.

cold: always wondered that but i've never tried

fox:
"rip" does not mean lossless.

from their own website: " MakeMKV is a format converter, otherwise called "transcoder"." = NOT lossless, and as far as i remember from the DVD days, transcoders = suck . (just like other softwares it might have options to keep audio/video untouched but whatever)

You are totally wrong on this. Enough said. Go research.

Yes. Completely wrong. Do you have a link?

All MakeMKV does is take the video file(s) and the audio file(s) from the BluRay or DVD and put them in a .mkv container. It doesn't do any compression.

I think what you are thinking of having is something like "AccurateRip" that is used to verify the accuracy of an audio CD rip.
