For some editing software as I'm sure you guessed !

What I like to do is use FRAPS (free video recording program for computers) and record scenes in games (specifically World of Warcraft). I use WoW Model Viewer (A WoW data base with all the wonderful variables possible with characters and objects in the game. Fraps, once again, can record my manipulations) to "attempt" some cool scenes etc. Then of course I use Windows Movie Maker to put it all together, add and edit clips, and add transitions. However...it just doesn't have a clean, shiny finish, with all the great manipulations I'd like....

Example of what I have so far:
YouTube - DragonsOrders's Channel ( WoW's falling angle is probably my best example of what I was TRYING to accomplish).

What I want: I want to purchase software that allows me to record things on my Computer (In video games, paint, etc.). Fraps is free so it has thier little promo on my videos...I hate that. I want, of course, my software to be able to edit clips (cut, meld, trim, freeze frame); as well as provide me with TONS of awesometransitions, and video effects. On top of that I want to be able to Multi-Layer my videos (Extremely important! I want to be able to edit layer upon layer into my videos to create scenes that flow together. Can't do that without something that can layer several different video's without a fuss!)!

Any ideas? I have never purchased video editing software and will most likely approach Best Buy to look for some (I would assume that's where you go anyway...). I don't know what I need to look for on the boxes so I thought I'd ask for some advice to push me in the right direction into getting exactly what I want.
