MKV Matroska video container is like bank . It working so well, but what is inside?

I did some research, with focus on my own HD content in the MKV files.

Video:

• h.264 /AVC1 – nice video codec usually encoded by x264 , his quality is very, very good .

Audio:

• DD DolbyDigital 5.1 6.1, which is internally marked as a/52 or AC-3 (this confused me for the very long time ), DD Is the classic one and very popular, but quality isn’t top.
• DTS Digital Theater System 5.1, DTS-ES 6.1 – DTS is better than the DD. Especially in concerts is DTS the must (or pure uncompressed LPCM).

Subtitle:

• SRT – text subtitles
• IDX – VobSub subtitles
• SUB

Subtitle is usually inside the MKV file (this was news for me too, firstly I’m looking only for audio and video inside the MKV, and what i find, that i don’t need search subtitles on web, firstly i must look deeply inside the MKV container, if subtitle isn’t inside it), but if someone forget margin it inside, you will find .IDX or .SUB file together with the Matroska file.

Tools:

One of the best free tool to display detailed audio and video specification (not only of the .MKV file) is MediaInfo . It working nice and accurate. It’s easy to right-click on any video file, and take instantly all this detailed information about bitrates, resolutions,…

Player:

And finally the good player is VLC . Try new VLC betas with tons of new features. And don’t forget to set S/PDIF to your audio receiver (if your receiver support direct digital stream), the audio quality will be the top one.
