MKVToolNix is a set of tools to create, alter, split, join and inspect Matroska files(mkv). 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 multimedia file format aiming to become THE new container format for the future. Use MKVCleaver or gMKVExtractGUI to extract/demultiplex mkv video and audio files.

Version history / Release notes / Changelog
# Version 63.0.0 "Everything" 2021-11-14
## New features and enhancements
* mkvmerge: AC-3 parser: E-AC-3 with BSID values > 10 and 15 are recognized now, too. Implements #3211.
* mkvmerge: when using language codes for track selection (e.g. `-a und,en`) all tracks that do not have a language property (due to their container not providing one, e.g. AVIs) will be treated as if they did have one set to `und` ("undetermined") as that is the language the track will have in the Matroska file anyway. Before this change it wasn't possible to match such tracks via language codes.
* MKVToolNix GUI: only on Windows: when compiled with Qt 5.14 and < 6 (which is the case for the officially provided binaries) fractional screen scaling will be enabled. This means that the GUI will be scaled appropriately if Windows is set to 125%, 150% or 175% instead of being too small or too large. Implements #3043.
* MKVToolNix GUI: the spinner in the bottom right corner will now be hidden when no jobs are currently running. Implements #3225.
* MKVToolNix GUI: header editor: a new column has been added to the tree view showing the status of the "track enabled" flag. The information is also shown on the track overview page on the right. Implements #3228.
* MKVToolNix GUI: header editor: users can now reorder tracks by dragging & dropping. Implements #3227.
## Bug fixes
* mkvmerge: AVI reader: fixed reading AVI files that contain `vprp` video properties header chunks; reading aborted too early. Fixes #3209.

People... really... WOW, longwin, write one yourself and let people like yourself, cut down all your hard work, that should make YOU feel REAL GOOD, Right? Oh, wait, you don't know how, you can only gripe about what others are doing for free. Don't bother to THANK them for all the time they do spend on developing the software and to GIVE IT AWAY... I got an idea, how about reporting the bug and go on about your business... sounds like you don't have a clue of what goes into developing software for other people to use and for them to download it, then try to install it on thousands of different computer hardware set ups & different version of Windows etc.. and the USERS computers having all kinds of buggy issues, then in turn, they GRIPE at the developers, which tries very hard to understand all the peoples issues and helps them out by staying up late nights and put TONS of hour into it, but you go ahead and bitch, moan, groan and gripe about it, they all deserve your hateful, spiteful temperament. I don't know of any good/great software that isn't updated on a regular basis to keep all people happy in use it... well almost ALL people.
I use this software a lot and it always works 100% of the time and my THANKS goes out to the people that make this software possible!!!

The author fixed so many bugs and create a new one (as far as I know).
So the program always has bugs to fixed. And version number will be 1000.0 soon.
After running mkvmerge, the information throwed by program is garbage.
May be this fixed and another new one is created.

HighCode : Must be a problem on your part.
Using Windows 10 64bit, MKVToolNix 56.0.0 and it works flawlessy (as previous versions), I can edit every field everywhere.
A very great and useful tool, hope they give it a GUI also for extracting tracks and it would be A-W-E-S-O-M-E.
But if you need to remux something, this is the best application you can find: 100% reliable and very easy to use.

The new version has the Proprieties on right side grayed out so I cant chose language or default flag for sound and subtitles. Uninstalled and installed an old version.
