MKVToolNix v63.0.0 released

Heyo!

The last couple of months have been pretty quiet regarding MKVToolNix as I’m still struggling to find time, motivation & energy for after-hour coding in general and work on MKVToolNix in particular. There are several topics on my TODO list that are rather big & require lots of work, e.g. improving Dolby Vision support further or implementing support for VVC/H.266. I’m therefore glad that some users posted a couple of bug reports & feature requests that turned out to be small enough for me to fix & implement quickly: sometimes such small wins are desperately needed.

But that’s probably more than you wanted to know. Anyway, here’s a new release with a couple of small improvements.

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

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 β‰₯ 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.

Have fun! ☺

    Mr. Bunkus. I have been going through various help files and sites that contains help on your very widely used software MKVToolnix, and I can’t seem to find a solution, so I try here. Task: I have 23 files and the corresponding number of subtitles. Is there a way I can do it all in one swipe without the output file being same size as the 23 files combined??? As in pairing “S01E01” with “the subtitle named 01.srt, pairing “S01E02” with subtitle 02.srt?? Thanks for a super useful program. I combined it it with “TextCrawler” that makes goig through subtitles looking for a specific phrase SO much easier. Have a nice day. Benny in Denmark.

    Greetings Moritz,

    There is no doubt we are living in challenging times and finding motivation, even for the things we enjoy doing, can sometimes be difficult.

    Thank you for your ongoing dedication to developing MKVToolNix and I applaud that you are sharing your struggles and triumphs with your audience. Even when the wins appear small, the big win is we get to enjoy this wonderful software you continue to develop, and to do so without the expectation of payment is a bonus.

    Our family extends our best wishes to you and your family for the festive season. We hope you can relax and recharge spending time with family and friends, and be refreshed to approach the new year with renewed vigour.

    Kind regards,

    Jason & Family.

      Thank you SO MUCH, Jason, for your kind words! Please know how much they mean to me. As a software developer & maintainer I (and lots of others in similar positions) often have to deal with requests, demands, sometimes disrespect, outright hostility & negativity, all of which is very emotionally draining. Positive feedback is rare, even more so heartfelt one such as yours. I really, really appreciate it. Hope you & yours can stay healthy & have happy holidays, however you may spend it.
