MKVToolnix GUI DOWNLOADMKVToolNix GUI is one of the best collection of tools (mkvmerge, mkvinfo, mkvextract, mkvpropedit and mmg) for modifying MKV files.

The graphical user interface (GUI) of the software allows you to manipulate Matroska (MKV) files in several ways.

You can use those tools to create, split, edit, mux, demux, merge, extractor 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 software 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.

Changes in MKVToolnix 45.0

New features and enhancements

  • mkvmerge: mkvmerge has never supported appending & splitting FLAC audio tracks. mkvmerge will now emit error messages when the user attempts either instead of continuing and creating invalid FLAC tracks.
  • MKVToolNix GUI: added an option in the preferences to turn on eliding text on tab headers. If enabled, tab names will be shortened so that all tab headers fit into the window’s width.
  • MKVToolNix GUI: added an option in the preferences to disable all tooltips.
  • MKVToolNix GUI: Windows: debug output sent via Qt’s to Windows’ debugging facility will use a more verbose message format including the application name, making it easier to filter for in SysInternal’s “Debug View” utility.
  • MKVToolNix GUI: multiplexer: if the file identification fails due to a JSON parser error, the output generated by `mkvmerge` will be output via Qt’s debugging facility (viewable with SysInternal’s “Debug View” utility on Windows; on other systems, it’s output on `STDERR`) allowing insight into what’s gone wrong.
  • MKVToolNix GUI: multiplexer: if an error occurs during file identification, the name of the processed file will be mentioned in the error message.
  • MKVToolNix GUI: multiplexer: if an error occurs during the identification of multiple files, the GUI will ask the user whether to continue or abort the identification process.
  • MKVToolNix GUI: job queue: added an option in the preferences for removing completed jobs when exiting the program depending on their status.

Bug fixes

  • mkvmerge: H.265/HEVC packetizer: fixed changing the NALU size length, it was using the wrong offset into the `hevcC` structure.
  • mkvmerge: MP4 reader: fixed calculating the duration of video tracks that only contain a single frame.
  • mkvmerge: MP4 reader: if there’s no frame offset table (`ctts` atom) present for H.265/HEVC video tracks, mkvmerge will determine the timestamp order itself instead of relying on the timestamps in the MP4 being in the presentation order required by Matroska.
  • mkvpropedit: Windows: mkvpropedit wasn’t caching when reading the file to modify, slowing down operations such as adding track statistics tags considerably.
  • MKVToolNix GUI: multiplexer: when using the title as part of the destination filename (both automatically as well as using the “copy title to destination file name” function) all characters that aren’t valid in a file name are replaced by hyphens.
  • MKVToolNix GUI: multiplexer: the “copy title to destination file name” function was broken when the “make file name unique” option in the preferences was disabled. In that case, the file base name was removed regardless of what the title was set to at the time.
  • MKVToolNix GUI: multiplexer: when using the “show command line” menu option on Windows the path to the `mkvmerge` executable was shown with forwarding slashes instead of backslashes. This is a purely cosmetic fix as Windows supports both forward and backward slashes.
  • MKVToolNix GUI: multiplexer: when adding Blu-ray playlists the GUI used to only look for the English version of the disc library information (title & cover images). Now the GUI will present all disc library entries in the “select playlist to add” dialog & let the user chose which one to use (if any).
  • MKVToolNix GUI: multiplexer, info tool: fixed the “warn before overwriting” check wrt. jobs creating the same file.
