Personally I hate edits like that because they are not at all interesting or creative. You should definitely keep looking there are much better editors.
The only half way decent edit was the third one, he still over edited in some spots trying to slow the game play down to match the tempo in my opinion. If you would like to see a better, more diverse editor look up my home boy on the tube: Iphenomarts
So you found someone that knows how to use After Effects plugins. This guy is just a generic CoD editor, nothing special.
Youtube.com/user/initial, the editors here are at least creative with there song choices and there editing. It pisses me off that all CoD editors seem to do nowadays is stick a few wobbles in and motion track some text and call it an edit. You can barely see the kills past all the flares and shit.
