MKVToolNix GUI is an open-source user interface for a set of highly useful MKV-related tools. Here you can merge MKV files, split them into smaller parts, extract their various audio and video streams, edit their headers and chapters, and convert video files of the most popular video formats into MKV containers.
This MKV toolbox includes three main utilities – mkvinfo, to provide you with extensive technical information about a selected Matroska file; mkvextract, to extract data and streams from Matroska containers, and mkvmerge, to convert MKV files from other media files or to create new ones. Mkvinfo comes with its own GUI, while the other tools have been neatly integrated into MKVToolNix GUI. Here you can add as many supported video files to the conversion list using the Input tab – you will be presented with a parallel list of all the tracks included in the various files and the specific codec they use, as well as the language code assigned to them. You can select which tracks will be muxed and therefore included in the resulting MKV file, give them a new track name, a new language code, extra conversion parameters, etc. The Output tab will let you add metadata and new chapters to the output MKV file, and split it into various segments by size, duration, timecodes, etc. Finally, you can add so-called “attachments” to the Matroska file, such as pictures, fonts for subtitles, background information in text form, etc. more
Split MP3 files into smaller parts or join MP3 files together into a bigger one.

if they add in ability for more video types to be muxed into mkv container it will be even more perfect.
