I got halo awhile back from a friend. (best 10 bucks I ever spent) and then I discovered Fraps. I used that for awile before I discovered how to use dev mode's camera. I then got the full version of fraps which is nice. and I use Studio 8 to edit all my movies to perfection.
(UPDATE) Alot of things have happened since I first began making movies. Firstly I got rid of my old PC, the one with Studio 8... Now I have a mac and any videos that I'll be posting from here on will most likely be made off of iMovie.
(Update: Built myself a PC. Got Adobe After Effects and Sony Vegas Pro 13. I'll make whatever I want in regards to videos.)
