How have I not heard about this until now?
We have a few individual licenses for Camtasia, the software we use for creating video tutorials. It's fairly expensive, so a couple of us have it installed on our personal workstations, and everyone else has to go to one of a couple of shared computers or over to the technology lab in order to use it. The result, of course, is that almost no one creates videos.
At the GOLD GALILEO conference on Friday, I learned of the existence of CamStudio, a free open source equivalent. I haven't played with it much yet, and I think it lacks a bell and/or whistle here and there compared to Camtasia, but it seems like between CamStudio and Audacity, that would cover most media production needs for free.
