Camtasia is good, but not for games. I strongly (imo) suggest PlayClaw. Fraps rocks too if you have a big amount of disk space, but the same quality comes from PlayClaw, and it's only 1 GB for 10 minutes of playing, as Fraps with same options is 3 GB in 1 minute! (This is just for me). For webcam record I suggest the ol Movie Maker. it's simple, but you have to edit it to sync completely. The facecam can be put in with Sony Vegas Pro 11 easily.
Wow. Just wow. The most epic and interesting topic ever made. This is pure quality, the thumbnails and stuff too, just awesome. Keep up this good work and you will be a famous youtuber in no time. Big heads up, dont ever stop making quality things like this, and a nice broday to you
