MKVtoolnix is a set of tools for creating and modifying MKV files. The application is comand-line based, but the Windows version has a graphical interface called the MKVmerge GUI.
There is an amazing list of supported input formats. Although this application is more for advanced users, anyone can use it to perform basic tasks. For example, when you add a video file, MKVtoolnix will return you how many parts the file contains. For example, for an XVID clip, it returns the XVID video part and the AC3 audio part. When you are ready to convert files to MKV, just click the Start muxing button at the bottom of the page.
This free program has options for subtitles, video, audio and format-specific settings. In short, MKVtoolnix can offer a lot of functionality, but when it comes to video files, you can really appreciate its capabilities.
MKVToolnix is a package of tools for working with the Matroska container format (MKA and MKV) and more precisely collecting individual streams (video, audio, subtitles, etc.) in the appropriate format and splitting an MKA / MKV file into its constituent streams. The program offers full use of the capabilities of the Matroska format: embedding more than one stream for video, audio and subtitles, embedding fonts and other files, splitting, creating so-called chapters and more.
