I wanted to demonstrate the SpamBayes plug-in for the school, and I realized I ought to try the screen-capture feature of the free Windows Media Encoder 9. The results were stunning. via [Jon's Radio]
I used that codec for a video on programming the Tablet PC I did last year. It's amazingly compact. I don't think one can dynamically switch codecs in the middle of a video, though, so you can't have a talking- head segment followed by a screenshot video with segment-specific codecs. Pity.
