The Growler guncam only adds the basic layers, grain, lines & desaturate. It doesnt fiddle with the lighting or anything, one can achieve almost the same thing with windows movie maker. I had a pair of scripts for VirtualDub when I used to make guncam vids and it made it look great, it added flickering adjusted contrast, grain etc. etc. came up with very real looking vids. Too bad I lost the scripts. I think it was called a "GunCamBundle" or something similar.

Here's an comparisation of Growler vs. the VirtualDub script
