Fraps doesn't edit, just records.  You can use Windows Movie Maker that comes free with Service Pack 2, or download it off the window catalog site, it's free & will give you all the tools to make a film.  A lot of good films have been done using WMM.  That's the only free one I know of.  Use that to make your first couple films.  If you decided to stick with it, I'll help ya find a better program for free or cheap.
