How to remove tag spam and set language in several MKV files at once

I wanted to add to pieces of information to this tread:

  1. Regarding Bulk updates of MKV (and also MP4) files, I made good experiences with MP3Tag (Windows). Although it is geared towards tagging MP3 files, it works equally well on video files e.g. for removing Title, Year, Genre and also has an option to Remove Cover.
    It scans whole directory trees for supported files and you can then designate a subset on which to perform bulk edits.
    It has been mentioned here and here before, but I wanted to give this tool a bump, as it does most of what the scripts above aim to do, but with a good GUI.
    It can be freely used without restrictions but asks for a donation. (I have no affiliation with the author)

  2. MP3Tag does not handle language tags on the videos or audio tracks, though. I am not happy with the undiscerning “bulk delete all” or “bulk set to language X” approaches discussed above. So I wanted to shamelessly promote a feature request I created recently: Automated detection and handling of audio and subtitle languages Please comment/vote if this topic is close to your heart as well.
