HandBrake script for recursive batch convertion on Mac OS X & Linux

I wrote a script to recursively batch encode video files using HandBrake.

I needed to convert a bunch of AVIs into M4V so I wrote this script to convert all AVIs under a directory, with sub-directories, into M4V. The script will find all files of a given file type and then convert them (via HandBrake) into the specified file type. It’ll place the new, output file in the same directory as input file.

I’ve tested this to work on Mac OS X Lion but it should work on other versions of OSX and Linux too.

Here’s a link to my GitHub project that’ll always have the most up-to-date version:
