====== Ubuntu - Video - Join MKV files ======

Joining Two MKV files.

----

===== Use mkvtoolnix =====

<code bash>
sudo apt-get install mkvtoolnix mkvtoolnix-gui
</code>


  * Start mmg (graphical user interface for mkvmerge)
  * "Add" the first file
  * "Append" the second one, third, fourth, ...
  * Set output name in the textbox at the bottom
  * "Start muxing"

Subtitles are preserved and properly concatenated, so are audio and video. Chapters can be edited in the resulting file with mmg.

This procedure creates a properly muxed file.

Any problems should be mentioned in the "log"-window in mmg.

You can even set and name audio and subtitle tracks with the correct language codes and Annotations like "Forced" or "Directors Commentary".

----

===== Use mkvmerge =====

If you plan to do this repeatedly on different files you better use the command line version mkvmerge (<nowiki>"mkvmerge --help"</nowiki>)

<code bash>
mkvmerge -o output.mkv input1.mkv +input2.mkv
