I saw that Exiftool can't write MP3 or MP4 Files. So I can't change Metadata in this files with Exiftool. Has anyone a way to write/change/delete some Metadata Entrys?
I know that there are many tools out to do that. But I will only change ONE Metadata. Many tools create own Tags change other tags or do something else that I don't want. With Exiftool I can limit my changes to the tag that I specify in the Comandline.
