Version history / Release notes / Changelog:
2015-07-18 Moritz Bunkus <moritz@bunkus.org>
* Released v8.2.0.
* 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. '<NUM:3>'. 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.

2015-07-15 Moritz Bunkus <moritz@bunkus.org>
* MKVToolNix GUI: new feature: the position of the tab headers of all tab widgets can be changed in the preferences. Implements #1334.

2015-07-12 Moritz Bunkus <moritz@bunkus.org>
* MKVToolNix GUI: new feature: added an option for hiding the tool selector.
* MKVToolNix GUI: new job queue feature: added menu options for stopping the queue either immediately or after the current job has finished. Implements #1303.

* MKVToolNix GUI: merge tool enhancement: the dialog shown after dragging & dropping files from external applications asking if those files should be added or appended now has an option to always add and never to show that dialog again. For new MKVToolNix installations the default is now to show this dialog again until the user deactivates it either in the dialog or in the preferences.
* MKVToolNix GUI: new feature: added additional ways to move selected files, tracks and attachments around: keyboard shortcuts (Ctrl+Up and Ctrl+Down) and optional buttons (those have to be enabled in the preferences). Using drag & drop remains possible. Implements #1279.

2015-07-05 Moritz Bunkus <moritz@bunkus.org>
* MKVToolNix GUI: bug fix: if a GUI language other than English was selected then the warning/error messages output by mkvmerge were not recognized properly and output in the wrong text views.

2015-07-04 Moritz Bunkus <moritz@bunkus.org>

* MKVToolNix GUI: enhancement: several drop down boxes have had their options renamed slightly to be more consistent overall and easier to select via the keyboard. Implements #1309.
* MKVToolNix GUI: fix compilation with the upcoming Qt 5.5.0. Fixes #1328.

2015-06-30 Moritz Bunkus <moritz@bunkus.org>
* MKVToolNix GUI: job queue bug fix: when re-starting a job the »date finished« field wasn't reset. Fixes #1323.
* MKVToolNix GUI: merge tool bug fix: the option »set output file name relative to first input file« caused the relative path to be applied each time a file was added resulting in the wrong directory. Fixes #1321.

This is a great set of tools, handling all sorts of files for my favourite container, Matroska.
But, I really needed a way to process multiple files, and setting up each individual file with virtually identical settings began to wear on me.
So...
I wrote a batch program which will process a *lot* of files at one go. I call it MKVBatch, available on this site. Makes my life a lot simpler.
A profound Thank You to Moritz Bunkus for MKVToolnix.

@b8375629: You seriously came here to rate this prog bad, complaining about a lackin batch/job queue function!?
Earned the price for the most self embarassing comment all around, also "value for money 1/10"? Really, so how much you paid for it? Stupid kids on the i-net, gotta love them :)
Great great tool set, thanks for that! (don't like the new Gui too much yet, though :/)

@b8375629 there IS a job queue function. You just don't know how to use the program. Ctrl-J brings up the queue. there is a big button at the bottom to "add to job queue".

Fanboy damage control aside, I stand by my earlier statement. This program is quite tedious and time-consuming when processing multiple files. The job queue 'isn't the best' because there is no job queue function to begin with. This is not a minor drawback in today's day & age.

No other program does what this does. This is the way to multiplex mkv PERIOD. Despite some minor drawbacks (e.g. the job queue isn't the best) it always does a good job, never crashes, constant development. Kudos for this remarkable tool.

This program lacks a batch file function. Many of today's encoders have the capability of putting multiple .mkv or .avi files into a que list for processing. If one has say 15 - 20 video files from a series, it gets quite tedious ticking and un-ticking boxes, doing each file one at a time. Pretty lacking by today's standards.

I thought it was failing to append for no good reason, but but the snippet I'd cut off to join (with another program) had gotten converted rather than copied.

MKVToolnix is a great tool, but not without flaws.

To begin with it would be appreciated that ANSI subtitle files would be auto-converted to UTF-8 on some languages, otherwise some characters won't show fine.

There are some issues when muxing with contained files, like say, a h264 stream and a mp4 contained AAC stream. In this situation it's possible the audio won't play in your output file.

I would also had like for some time now that you could choose what pieces to keep when splitting a file, avoiding to write to disk the whole video.

Normally when muxing out a file you will encounter some errors in the log window. Sometimes without describing exactly the reason, nor allowing you to find it somewhere else on the net, leaving you wondering.

Finally in recent versions, probably since 7.0.0, MKVToolNix takes almost double the time for the remux (ie 6 minutes instead of 3). This was voiced in its support thread but nobody replied back. My system is a standard recent one 4670K, 8Gb 1600, 750 Ti on Win7x64 SP1, so this is something that should affect generally and a serious regression in my humble opinion.

This is hands-down the BEST video editing software in the market, period !! I have been using mkvtollnix since version 7.1.0, converted many of my Blu-ray to MKV files from various formats (DTS HDMA, TrueHD, m2ts, ts, etc.), as well as adding additional audio/subtitle tracks to a movie, it is extremely reliable and very simple to use. I also use tsMuxeR, but my experience is that txMuxeR is less reliable, it actually failed on me on multiple occations. Since version 7.2.0, mkvtoolnix added support for "play-list" (.mpls) files - this is freaking awesome, it is very helpful if you want to convert the "seamless branching" Blu-rays, mkvtoolnix will read the Blu-ray structure for you, and you no longer need to add each A/V file individually to the main page in order to piece them together for the whole movie.

I ran the MKVtoolnix 7.2.0 on both Portable and Installer through VirusTotal and Panda reports "Eicar.Mod" as a Suspicious file. I then checked MKVtoolnix 7.1.0 and it is Clean. So, may be the Author can shed some light on this, until then I am staying with 7.1.0 Portable.

Easy to use tool for multiplexing Matroska streams with a Windows native GUI. Flexible, logically organized, and supports almost all source formats well. De facto standard.

The existance of this GUI program is a major reason for the success of MKV. Creating files this format is so much easier and overall more reliable than working with AVIs or MPEG Programs, let alone MP4s. Last time I checked, MkvToolNix did not have a tag editor. And it is not a coincidence that very few other programs can display tags, and nearly no releases are actually tagged. (It is possible to use a recent version of foobar2000 for fast, customizable tagging.)

During its development, the author has made a number significant changes to the format of files written by MkvToolNix, such as the format of MPEG sequence headers, stream header compression, and presence of a seek element, which might not be immediately apparent. Some of these changes had since been reverted. I would excercise caution before upgrading to a new version, thoroughly read the changelog and test that the output files are working on all devices and players they are intended to work, and that no unexpected artifacts appear and seeking works.
