iMovie versus Garageband for podcasts

Marisa Guastaferro and I collaborate on a Romeo and Juliet podcast. In previous years, the students have used Garageband to put merge images, audio, and music. However, the finished product is a small video that is really ideal for viewing on an iPod and not a big screen. I used to use Quicktime to export their podcast into a bigger format, but it was still pixelated. This year, we decided to use iMovie to blend our projects. I found the above tutorial for creating a slideshow with soundtrack in iMovie.
