Description
MKVToolNix is a small collection of tools (mkvmerge, mkvinfo, mkvextract, mkvpropedit and MKVToolNix GUI) that allows you to manipulate Matroska (MKV) files in several ways.
You can use MKVToolNix to create, split, edit, mux, demux, merge, extract or inspect Matroska files. The program will also work with other video formats (AVI, MPEG, MP4, Ogg/OGM, RealVideo, MPEG1/2, h264/AVC, Dirac, VC1) including some video codecs (such as VP9 video codec support - reading from IVF/Matroska/WebM files, extract to IVF files). It also works with audio formats (AAC, FLAC, MP2, MP3, (E)AC3, DTS/DTS-HD, Vorbis, RealAudio) and most subtitle formats (SRT, PGS/SUP, VobSub, ASS, SSA, etc.). MKVToolNix is a cross-platform application that will work on Windows, macOS and Linux. If you're looking for a Linux version, you can download one from the MKVToolNix homepage.
MKVToolNix is written by Moritz Bunkus.
MKVToolNix Review
Note: If you're looking for more information on how to compile MKVToolNix yourself, check the README file (online).
Other command line tools (example: mkvinfo)
To use the command line tools in Windows, open a Command Prompt window.
In the command prompt, you can try each program (mkvmerge, mkvinfo, mkvextract, mkvpropedit) by typing its name and the usage parameters. An example would be: "mkvinfo --help" that will display a list with all the commands available.
Tips
Besides the usual standard documentation from the command prompt (I hate it because it's hard to read) you can find and read the online documentation available on MKVToolNix documentation homepage here (use the links for mkvmerge, mkvinfo, mkvextract and mkvpropedit to access the online help).
Final Conclusion
You can learn how to use several main features in minutes but to master the program, it does require more time. Your best bet is to experiment with all of its options and whenever you need some help, check the FAQ section (filled with great answers to common issues) and check the documentation for all the tools - here (provided once again). MKVToolNix is a "must-have" software if you work with MKV files. It has an incredible amount of features that are not listed on the homepage.
