Has anyone used screen recording software as an alternative to windows moviemaker?

I was wondering if there are any snags to taking this approach as opposed to using moviemaker, which horribly degrades the images.

Powerpoint…insert screen recording. Save as. Done.

Camtasia does a very good job, offers high quality settings, and has a very powerful video editor.

I use FastStone capture. Lot’s of good features that I can’t live without. That includes all sorts of screen captures, editing, highliting and video recording.
