I've been looking at video capture solutions for Mac. There aren't any for free, so be prepared to shell out some cash. ScreenFlow is incredible, but for $99, it was too expensive and had many features I simply didn't need. I ended up purchasing iShowU, for $20. It does exactly what I need it to do: capture my screen and give me many options for encoding and quality. Here's a short video I made with the application. EDIT: The video is crap; I don't know what happened. I'll try to get a better one up later.
