Written in anticipation of the Apple TV, Transmogrify is solution for transcoding movies into a iPod, iTunes and Apple TV suitable formats using OS X Folder Actions. It is a collection of Perl, AppleScript and some native C which automatically converts most movies dropped into a folder to mp4 files.

Thanks must go to Tom Sutcliffe for writing the C utility which sets the folder icons.

The script contains ffmpeg, the project page for which can be found here.


  1. Install the package.
  2. Once installed, just open the ‘Folder Actions Setup’ dialog and add the Transmogrify script to the desired folder.
