Here's how to get in touch with other MKVToolNix users and the developer:

  • MKVToolNix sub-Reddit: ask any kind of question here
  • Doom9's forum: in-depth discussions on video topics in general and MKVToolNix in particular can be found here
  • Bug reports & feature requests: please file them over at the Gitlab project site
  • IRC: we have a #matroska channel over at (I'm "mosu" there).
  • Twitter: I'm @MoritzBunkus there
  • If you need to, you can reach me via email at, but I prefer you asking questions on one of the public sites listed above as the answers to your question will often help other users, too.
