Screen capture software

I've been trying out some screen capture programs to get footage of my rigging goodies in action to throw 'em on my demo reel. So far I've tried two programs, with mixed results...

Copernicus: On the plus side, this program's free to use, and it's also available for mac. Unfortunately, the quality of the output is pretty bad, and you can't really mess with the settings too much. A lot of the captured frames seem to be blended between camera moves, and therefore get some weird artifacting. But, on the other hand, it pumped out a file successfully.

Camtasia: This was recommended to me by dudes at www.strutyourreel.com, and it's once again got some ups and downs. For one, there's no mac version, but that's pretty minor; I just rebooted in windows and installed it there instead. For another thing, it's only a 30 day trial. Bummer. And lastly, although it pumped out a native format video file (.camtec) it took me a couple tries to get the file format I wanted. However, the ends justify the means, and Camtasia's final output was great. The quicktime file I ended up with is great quality, and I look forward to replacing the ugly, way-too-fast copernicus footage.
