MetaZ is an MP4 metadata editor for OS X.
It started its life when another great metadata editor, MetaX, stopped getting updated. Some of the web services it used changed in ways that broke functionality and it had some really annoying (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.
