I made an experimental video version of Friday's lecture, based on Apple Keynote. It is regular audio on top of Keynote slides, mixed down into a Quicktime movie. For this reason, it is about 187 Mb in size... a hefty download.
Because it is so large, I slapped it into a new, special tab on our iTunes U page, as shown in the diagram: "Video lecture." It is significantly different from the enhanced audio podcasts from previous lectures. I am not sure yet if I like it, so see how you like it. Remember, we are the pioneers on iTunes U at UCF, so we have to sort out the good from the bad.
P.S. I still have a few regular enhanced audio podcasts to upload, from earlier in the week, Nov. 4 and Nov. 2!
