You didn't mention what platform you're working on, so I don't know
if you can use Ambrosia Software's Snapz Pro X 2, for Mac OS X ($69).
It's a great screen movie capture utility that we use to make lab
training videos.

To use a screen capture such as this one successfully, you need to
understand optimal resolution and color settings and choose the right
export codec for the video. The manual usually covers these topics well.
We export our screen capture video to DV format then edit that in
Final Cut Pro for pretty good results. We export the finished video
using the H.264 codec for LAN delivery. (H.264 requires a pretty fast
processor to render on playback, so your computer needs to be less
than 3 years old or so.) If the only thing we're exporting is screen
capture video (i.e., not combined with video camera footage), then we
use the Animation codec at 10f/s.
Good luck,
John
