I have just uploaded a simple tag reader for reading m4v/mp4 video files tags.
This one may not find a lot of uses with the bulk of you , i really wrote it for myself as a clean and fast way of viewing tags on my files.
Its just a reader, not a writer but may well be the first stop onto a fully featured editor.
Just run it , drap and drop files to it and double click any file to view its tags. Simplez
I’d be interested to find out of anyone actually uses this….
