This session description mentioned Camtasia so I was really hoping to see the process of creating a video. This presenter had some great ideas but didn't show Camtasia - just some screen shots.
She makes videos of herself for her subs which I thought was a great idea. She also makes short clips of assignments so she isn't spending time during class reviewing. This allows her to have the more advanced students move ahead while she spends more time on the ones that need help.
