Man, this video stuff is hard work

Last January, just before teaching my first one-day Tech class at the
University of Michigan, I noticed that there was a sign on the wall that
said that lectures in the room could be video recorded. I mentioned that
toÂ*Jameson, KD8PIJ, one of my hosts that morning, and he said, Let me go
check on that. To make a long story short,Â*he figured out how to record the
class, and now, I have 35 GBytes of video in two .mov files on my hard
drive.

I finally got around to editing it today. Not being very experienced at
this, it took me nearly five hours to produce about 20 minutes of video. Of
course, in that time, I had to figure out how to use QuickTime (to clip
the .mov files and record the opening and closing credits) and iMovieÂ*to
piece it all together and produce the YouTube videos. The three videos
cover basic electrical principles, Ohms Law, and power:







After working on this for most of the day, Im sick of hearing myself talk.
And, I only have about five hours and 40 minutes of video left to produce.
