MKVToolNix

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

MKVToolNix 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 version 68.0.0

Updated on May 23 2022

New features and enhancements:
  • mkvmerge: HDMV PGS subtitles: mkvmerge now tries to detect bogus timestamps (where the current timestamp is two hours or more after the previous timestamp) & correct them to something more sensible (1s after the previous timestamp). That way one bogus timestamp cannot cause the rest of the frames to not be interleaved properly with the other audio & video packets.
  • mkvmerge: added colour information, colour mastering meta information & video projection information properties to the JSON identification format. The properties are reported for container types for which mkvmerge supports reading them (Matroska & MP4). The JSON identification format version number has been bumped to v15.
  • MKVToolNix GUI: multiplexer: added controls for all the video colour information & the video projection information.
Bug fixes:
  • mkvmerge: SRT reader: entries with a duration of 0 or less will now be skipped.
  • mkvpropedit, MKVToolNix GUI's chapter & header editors: fixed an invalid memory access when trying to update existing Matroska files whose EBML Head element had a "size" field length of eight bytes, and where rewriting said element would shrink the element by one byte. Files created by gstreamer fit the first part whereas the second depends on the changes requested by the user.
  • mkvpropedit, MKVToolNix GUI's chapter & header editors: fixed the programs not handling having to remove EBML void elements at the end of the file correctly and consequently aborting.
  • MKVToolNix GUI: the GUI now uses almost all SVG icons, allowing proper scaling even for scaling factors such as 125%.
  • MKVToolNix GUI: when compiled with Qt 5 the character set of INI files is forced to UTF-8 in order to fix reading INI files written by a version compiled with Qt 6.
Build system changes:
  • Qt's SVG library is now required.

Seems many people didn't know. If you mac won't open the file, just hold down 'control' while clicking the app, then choose 'open'. it will then always open.

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!!!!!

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.
