I have used GB to create several podcasts for my course. When I share them to disk and use Podcast Capture to put them on iTunesU, the images are very fuzzy. The original disk version is excellent when viewed with QuickTime. However, when I use QuickTime Screen Capture and submit the material via Podcast Capture the images look okay.
I ahev ensured that before I share the podcast from GarageBand, that I have selected the best quality for audio and maximum resolution (image size) for the thumbnails.
Does anyone have a suggestion on how to get better image quality to iTunesU?
