MKVToolnix 40

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.

# Version 40.0.0 "Old Town Road + Pony" 2019-11-09

## New features and enhancements

* mkvmerge: MP4 reader: added support for BMP covert art images.
* MKVToolNix GUI: multiplexer: added an option to disable deriving the
  destination file name from the file title. Implements #2648.
* MKVToolNix GUI: multiplexer: the content of the "stereoscopy" combo box has
  been simplified making the box's minimum width much smaller, allowing the
  user to resize the GUI's whole window to a much smaller width.
* MKVToolNix GUI: multiplexer: whenever the user changes the "aspect ratio" or
  "display dimensions" controls, the corresponding radio button will be
  activated automatically. Implements #2651.
* MKVToolNix GUI: Windows: added a setting in the preferences to disable the
  GUI's dark color mode even if Windows's app color mode is set to
  dark. Implements #2646.
* MKVToolNix GUI: Windows: replaced the dark mode introduced in v39 with
  another dark mode that's less wasteful with space between widgets.

## Bug fixes

* mkvmerge: MP4 reader: mkvmerge was reading eight bytes too many for cover
  art images. This could cause file identification to fail when the cover art
  was located at the end of the MP4 file. Even if it succeeded, this meant too
  much data present in the attachment. Fixes #2650.
* mkvmerge: MP4 reader: covert art images with unknown image types will be
  skipped instead of treated as JPEG images.
