Language in movie file tagged wrong - how to change?

I have been searching through the forum but could not find an answer that would help me. I am not familiar with command line tools which were the only ways I could find in the forum as suggested tools.

I have a movie (mp4 file) which has german audio only. However, the file was tagged with audio in english. I would like to edit this tag to correctly show the language as german.

I tried re-encoding with Handbrake, but it will not let me edit the audio track - as the source is tagged as being english the target file would be tagged as english as well.

Any suggestion would be appreciated

You could try with ffmpeg, something like this should work:
ffmpeg -i input.mp4 -c:a copy -c:s copy -c:v copy -map_metadata 0 -metadata:s:a:0 language=ger output.mp4

I had hoped for a more GUI version, but I will try. I am not comfortable with command lines, though…
