MKVToolNix is not a new software in the market and many people are well aware of its existence. But most people are still using it to read MKV files’ properties. This software is capable to do much more than just telling the details about a particular file.

MKV stands for Matroska and it is a file format like AVI, MP4, etc. The difference between this and other formats is that MKV can carry numerous audio and video sources in one file. This is very beneficial whet the content is dubbed in various languages. This is preferred by most people because it embeds the subtitles as well.

The above discussion makes it easily understandable why someone will require a tool like MKVToolNix. Yes, people install this tool in their computer to easily manage various audio and video sources from one file. This software works the opposite way also, it can help you merge various audio and video sources into one file.

MKVToolNix can be very easily installed in your computer. It is being reminded again that this software is a set of tools and you can do multiple tasks with it. Firstly, mkvInfo is a small application which tells you all the details about a particular file. It is useful for a regular user only if he/she knows the way to read the output.

The prime app is MKVToolNix GUI, which on first glance looks a straightforward and simple app. This helps you to do simple tasks like splitting videos and saving files into MKV format and many advanced tasks which you might not have done till now. Some of the simple video options are also available, such as resolution, aspect ratio, cropping, and others. With this app, you can also add subtitles by just loading a file.

Another vital task which you can accomplish via MKVToolNix is inclusion of chapters, similar to the old DVD format. With a little practice, you will surely make a simple video file special.

MKVToolnix 28.1.0 Jun 10, 2018 mkvmerge: AV1 parser: fixed an error in the sequence header parser if neither the `reduced_still_picture_header` nor the`frame_id_numbers_present_flag` is set. Part of the fix for #2410.

MKVToolnix 24.0.0 Jun 10, 2018 New features and enhancements:
mkvmerge: MP4 reader: improved the detection of edit lists consisting of two identical entries, each spanning the file's duration as given in the movie header atom. The second entry is ignored in such cases. See #2306.
mkvmerge: JSON identification: the "display unit" video track property is now reported as `display_unit`. The JSON schema has been bumped to v11 for this change.
mkvmerge, mkvextract: AVC/h.264: empty NALUs will now be removed.
mkvextract: VobSub extraction: empty SPU packets will now be dropped during extraction as other tools such as MP4Box cannot handle them correctly. Implements #2293.

Bug fixes:
mkvmerge: E-AC-3 parser: fixed determining the number of channels for streams that contain an AC-3 core with dependent E-AC-3 frames. Fixes #2283.
mkvmerge: Matroska reader: fixed mkvmerge buffering the whole file if a video track is multiplexed that consists of only one or a few frames. Fixes #2304.
MKVToolnix 20.0.0 Jan 15, 2018 Feature removal: several deprecated features have been removed:
* mkvmerge: the deprecated options `--identify-verbose` (and its counterpart
`-I`), `--identify-for-gui`, `--identify-for-mmg` and
`--identification-format verbose-text`
* all command line tools: support for the deprecated, old, proprietary format
used for option files
* all command line tools: support for passing command line options via the
deprecated environment variables `MKVTOOLNIX_OPTIONS`, `MKVEXTRACT_OPTIONS`,
* mkvinfo: most of its code was re-written in order to lay the groundwork for
including its functionality in MKVToolNix GUI but with more features than
the existing mkvinfo GUI. The result is that a lot of its output has been
changed slightly while keeping the basic layout. Changes include but aren't
limited to:
* Several element names are a bit clearer (e.g. `Maximum cache` instead of
