ProfCast

ProfCast looks like it could be a useful tool for podcasting PowerPoint and Keynote presentations on the Mac. I'm looking to try it out later this week; I'm most interested in seeing how large its recorded files get (trying to do something similar with IShowU created 1+ GB files for one of our testers, which far exceeds the 500 MB size limit for uploading to iTunes U).

Update

I did a sample recording the other night, and it looks pretty good. The slides are readable, and the audio is decent. The file size is also good; about 1 MB per 2 minutes of recording using the default setup. I've attached the file to this post; it's 2MB, about 5 minutes long, and recorded as an M4A (so it'll play in iTunes as an enhanced podcast). The program also has the ability to export as a .mov; I haven't experimented with that yet though.
