Include(ScreencastTeamHeader)

This is the script I use to convert screencasts to various formats

The script takes one argument which is the name of the video without the .avi file extension. It then makes videos with the format and resolution in the filename.

So 20070704_samba_filesharing.avi becomes (for example) 20070704_samba_filesharing_mpeg4_mp3_1280x720.avi.

Here's a test version where I generate 300K, 600K and 900K bitrate versions (to test and compare) and also use two-pass encoding. I need some serious help making this script easier. Help!
