What's more, you can set the aspect ratio, FPS, delay, stereoscopy mode, cropping, cues, compression mode, and custom command-line parameters for enhanced functionality. For example, when it comes to general track options, you can set the track name, language, default and forced track flags, tags, and timecodes. The tool enables you to view, append and take apart tracks, chapters and tags, as well as to edit a wide range of data. Linux users can resort to MKVToolnix for Linux. The full package includes separate command-line utilities for merging and extracting streams, viewing information, as well as for editing headers and chapters They are all wrapped up in a graphical interface in the Windows edition. It offers support for other popular video file types too, along with audio tracks and subtitles. MKVToolnix is an advanced application that enables you to open, examine, edit and mux Matroska files (.mkv). This behavior can be turned off in the preferences.

MKVToolNix GUI: multiplexer: the GUI will now check the state of the 'track enabled' flag of all video, audio & subtitle tracks when starting to multiplex or adding a job to the job queue.

MKVToolNix GUI: multiplexer: the default list colors used for distinguishing source files does not include the darkest tier anymore (the ones where one or two components are set to the value 0x3f) as they're hard to distinguish from each other.Note that this doesn't affect file identification.

Tracks of the same type will be sorted in the same order as their source files occur in the command-line arguments. The order is as follows: video tracks first followed by audio & subtitle tracks with other rarely used types of tracks last.

mkvmerge: tracks in the destination file will now be sorted by their type automatically unless the track order is specified with the `-track-order` option.
