With these tools one can get information about (mkvinfo) Matroska files, extract tracks/data from (mkvextract) Matroska files and create (mkvmerge) Matroska files from other media files. Matroska is a new multimedia file format aiming to become THE new container format for the future. You can find more information about it and its underlying technology, the Extensible Binary Meta Language (EBML), at http://www.matroska.org/

What's New:

  • MKVToolNix GUI: chapter editor enhancement: pressing return will cause the next appropriate chapter control to be selected depending on where the focus currently is: from a chapter input to the first chapter name, from a chapter name to the next chapter name and from the last chapter name to the next chapter entry's start time.
  • mkvmerge, MKVToolNix GUI: bug fix: fixed the container type not being recognized properly by the GUI. Now the numerical container type ID is output in verbose identification mode by mkvmerge.
  • MKVToolNix GUI: chapter editor enhancement: the template for chapter names can now contain a number of places for the chapter number, e.g. ‘’. The number will be zero-padded if there are less places than specified.
  • MKVToolNix GUI: new chapter editor feature: implemented a function for renumbering chapters. This allows the user to automatically assign new chapter names to one level of sub-chapters with ascending numbers. Implements #1355.
