iDentify is an OS X application for tagging iTunes compatible MP4 video files. When you add your files to iDentify, iDentify looks at the file, and, based on common naming formats, determines wether the video is a movie or tv show, and determines the name of the movie, tv series name, season #, episode #, year, imdb code. iDentify can then automatically look on The TVDB, The Movie DB, and tagChimp to gather more information about the title, such as description, rating, and more!

Limitations: iDentify 2 can look up and tag files forever, for free. However, if you register iDentify, several cool additional features can be unlocked, such as finder color labels, automatically adding to iTunes, and automatically renaming your files to fit your own naming conventions. The registration fee is only $9.95 payable via Paypal.

Requirements:
OS X 10.5+
Intel
