Create, alter, and inspect Matroska (mkv) files.

Overview

MKVtoolnix is a set of tools to create, alter, and inspect Matroska files under OS X, Linux and other Unices, and Windows. They do for Matroska what the OGMtools do for the OGM format and then some.

Since May 1st 2003, the Matroska libraries themselves and my Matroska tools are officially released as a first public beta version. Although all of them are still under heavy development, I urge you to download the software, test it and report any errors you encounter to me. I'm always grateful for good bug reports because I miss so many mistakes and you guys normally find them. Your feedback is important to me :)

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

What's new in MKVtoolnix

Version 37.0.0:
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.
Bug fixes
  • 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.

Works great and is a much needed tool if you want to mux e.g. old AVI files to MKV. Thanks, Jonathan for continuously providing those OSX builds (which would not exist otherwise!).

Doesn't start on 10.11 here (no crash on startup). The application is about 20 MB smaller than 29.0.0 and that sounds strange.

30.1.0 released but it requires Sierra, as most likely did 30.0.0, even though the Info.plist in package contents still lists Mavericks as minimum requirement.

Great app for complete control of MKV files. Will you be releasing a "Dark" version for Mojave?

Very good app. I would give all the stars if "Stretch by" would work on audio.

READ THIS: initial release of 9.7.1 would only launch on 10.12 Sierra due to inadvertent compiler setting. A new build, #4, is now available as of Dec 30 which runs on 10.9 and later. Download direct here (don't download from MacUpdate link): https://www.fosshub.com/MKVToolNix.html/MKVToolNix-9.7.1-build4.dmg If you're not sure what build you have, or if you get an error at launch about needing 10.12 or later to run, just make sure you get build #4. 5 stars for the developer Moritz for working it through and resolving it.
