The SubStation ssa plugin makes it easy to create open subtitles for low resoulution QuickTime movie, sometimes needed for iPhone and older video iPods, youTube or webcasts.
Thanks to the great work of the Perian
team, you just need to export a similarily named ssa file to a folder with a hi-quality avi.
If you open the avi Perian creates subtitles, respecting most of your settings when exportimg to ssa.
This file can be exported to any QuickTime format including iPhone and iPod.

Podcasts are for publishing new content periodically.
