MKVToolNix is a collection of tools for the Matroska multimedia container format (MKV) developed by Moritz Bunkus. It does for Matroska what OGMtools does for the OGM format.
Matroska files and tools are free and open source, and they are compatible with various platforms, such as Linux, BSD distributions, macOS, and Windows.
With these tools you can get information about Matroska files (mkvinfo), you can extract tracks and data from Matroska files (mkvextract) and create Matroska files (mkvmerge) from other multimedia files.
Matroska is a new multimedia file format with the goal of becoming the new container format for the future.
The tools can also be downloaded from video software vendors and FOSS repositories.
MKVToolNix can be used to create, split, edit, mux, demux, merge, extract, or inspect Matroska files.
The program It also has support to be able to perform actions with other popular video formats such as: AVI, MPEG, MP4, MPEG, Ogg / OGM, RealVideo, MPEG1 / 2, h264 / AVC, Dirac, VC1) including some video codecs (such as VP9 video codec support - reading from FIV / Matroska / WebM files, extract to IVF files).

About the new version of MKVToolNix 30.1.0 «Forever And More»
Recientemente This set of tools received a new version in this first week of 2019 and just a few days after the version was released, an update version was released that corrected some problems detected.
Of which they fixed the compilation system, since it was not fixed in UTF-8 and that in the GUI a bug with the multiplexer was fixed in which a solution for the drag and drop error is given.
Regarding the version for macOS with a bug with Qt 5.12 was fixed.
Another bug in the GUI that was fixed was with the chapter editor, when opening a Matroska / WebM file containing no chapters and later saving them again, the editor was truncating the file to a couple KB in size.
An of the new features added was in WAV extract as it will now write W64 files instead of WAV if the file name extension is `.w64` or if the final file size is larger than 4GB, the file size limit for WAV files.
On the other hand, the file controls, when you click on it, a menu with the ten most recently used output directories is displayed. Selecting one of them will change the destination file.
