It seems that ffmpeg is writing `TITLE` to the Segment Title and not to the Tags. Mp3tag only reads Tags and Chapter information from Matroska. I'll look into this.

@LyricsLover Matroska has a very advanced tagging system which seems to be not really supported by ffmpeg (at least not via these command line parameters).

If you're interested you can read [Matroska → Technical Info → Tags](https://matroska.org/technical/tagging.html) where the concept of _Target Types_ is discussed. It allows for the same tag field, e.g., artist to be stored for different levels. In this context T=50 means the album level and T=30 the track level. [Tag Field Mappings – Mp3tag Documentation](https://docs.mp3tag.de/mapping/) shows how Mp3tag maps, e.g., an `ARTIST` field on T=50 to the `ALBUMARTIST` field.
