About Mkv Default Track Changer
Mkv Default Track Changer is a small GUI application for changing the default audio and subtitle tracks in MKV video files. It runs on Windows, Linux and macOS and can edit several files at once, as long as they share the same audio and subtitle tracks. It changes only the file metadata without remuxing, which the project calls really fast. The source code is available under the GPL-3.0 license, and the app is downloaded from the project's GitHub releases page.
Pricing is not clearly stated.
