MetaZ is an mp4 meta-data editor for OS X.
It started its life when another great meta-data editor MetaX stopped getting updated, some of the web-services it used changed in ways that broke functionality and it had some really anoying (to us at least) little missing things like no proper window resizing. This lead to us starting MetaZ as a reimplementation of MetaX with a few ideas of our own sprinkled in there.
There are some files missing in the git repository that you will need if you are going to build your own version of MetaZ.
This file contains Amazon AWS access credentials.
Plugins/Amazon/Access_template.h and insert your own credentials.
These files are mostly just taken from MetaX but since I don't have the rights to use them they are not included in the repository.
I have though made a tar with these files and uploaded it to github: missing.tar.gz
