MKVToolNix is the one of the best collection of tools (mkvmerge, mkvinfo, mkvextract, mkvpropedit and mmg) for modifying MKV files.
The graphical user interface (GUI) of the program allows you to manipulate Matroska (MKV) files in several ways.
You can use those tools to create, split, edit, mux, demux, merge, extract or inspect Matroska files.
MKVToolnix will also work with other video formats. Such as AVI, MPEG, MP4, MPEG, Ogg/OGM, RealVideo, MPEG1/2, H264/AVC, Dirac, VC1.
And more as well as some video codecs such as VP9 video codec support – reading from IVF, Matroska, WebM files, extract to IVF files.
Moreover the program can work with audio files such as AAC, FLAC, MP2, MP3, AC3, DTS/DTS-HD, Vorbis, RealAudio. And also work with most subtitle formats including SRT, PGS/ SUP, VobSub, ASS, and SSA.
It is a cross-platform application that will work on Microsoft Windows (both 32 and 64-bit versions), Apple macOS and Linux operating systems.
Here is also the portable version which does not require installation. You just need to start the function. It can also be stored on external devices and run on any computer you have access to.
New features and enhancements
- MKVToolNix GUI: the list of often used languages now contains those from Wikipedia’s “List of languages by native speakers” by default. Also by default only those languages will be shown in the language drop-down boxes.
- MKVToolNix GUI: multiplexer: fixed a bug in the “make destination file names unique” logic that caused an existing number-in-parenthesis at the end of the file base name to be removed in certain situations (e.g. when the first added file was named `m (3).mkv` and both `m (3) (1).mkv` and `m (3) (2).mkv` existed already, the GUI was suddenly use `m.mkv` instead of `m (3) (3).mkv`).
- MKVToolNix GUI: on Windows the GUI is built with a slightly older version of the Qt library again (5.12.4). The Qt version used in release v36.0.0, v5.13.0, lead to crashes when doing certain things such as selecting multiple tracks in the multiplexer. Fixes #2605 and #26008.
