Batch convert videos with HandBrake CLI

handbrake-batch.sh

#!/bin/sh

# This script converts any kind of video the HandBrake CLI can handle
# into a 1000 kbit MPEG4 video and shrinks it down to a max width of 640 px.
#
# Usage:
# Running the script without any parameters just uses *all* files in the
# current directory and converts them, so make sure you only have video files
# in the directory you're in.
#
# You can specify an input and output directory if you want:
# 'script <INPUT> <OUTPUT>'
#
# The script also assumes you're using Mac OS X and have 'Growl' and 'growlnotify'
# installed, if you don't then just comment out the last line.
