I’ve been fooling around with ProfCast a bit and I must say– I LOVE IT. If you have a Mac and you make multimedia presentations, YOU NEED TO BUY PROFCAST. Wow, you don’t get much better of an endorsment than that (I don’t normally shamelessly push products, but this one will really help your teaching).
ProfCast is very easy to use. You just compose your presentation in Keynote (PowerPoint will also work if you really love uninspiring presentations that lock up on you) and drop it into ProfCast. Then, press record and you’re off to the races. At the conclusion of your presentation, ProfCast will open a wizard that will lead you through the podcast formatting process. I would post an example of my tests, but my built in microphone is next to useless, so as soon as I purchase a better mic I’ll upload a presentation.
