..aka video editing software. :P
I use Fraps as well, for recording.
Been out of the game too long about looking around for other video editing software, since myself, I've only been using 3 programs: Windows movie maker 2.0 (Windows XP days, yey), Sony Vegas (still using) and Adobe After Effects (not really ment for editing entire videos, but primarily for visual effects/graphics design etc..).
I'm sure there are some decent free video editing programs out there that you can use and get you started. :)
*Edit, maybe follow this link, I think some of these might work:
