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 44.0.0:
New features and enhancements:
  • MKVToolNix GUI: header editor: the attachments can now be reordered via drag & drop. Implements #2753.
Bug fixes:
  • Mkvmerge: Matroska reader: when encountering certain errors in the track headers such as the codec ID not being present mkvmerge will simply skip those tracks instead of exiting with an error. Fixes #2737.
  • MKVToolNix GUI: multiplexer: the "ask before overwriting" functionality did not look for the correct file names when splitting was active. Fixes #2741.

Was it NECESSARY to drop down the support of High Sierra? On WHAT has 10.4 and 5 more 'power'? For all what I know, High Sierra is still now the best 'professional OS X'; later ones are 'gimmicky' iOS prone downgrades adding funky 'Gadgets' (Gadget is a name! Of the French company who built the statue of libery in front of the New York harbour!) of no-use by a serious 'power-user', in fact NOT supporting useful utilities like FinderPop, exempli gratia!) GRRRRRR!!!!!

Multiplexing speed has increased dramatically compared to previous versions. A marked improvement.

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?
