1) get Fraps (or equivalent screen capture video software) and take lots of in game vids.
2) organize some good scenes with a few players (mainly so they can boast about having a hand in it)
3) cut the scenes from what you want to use and toss the garbage
4) find you a good song to put it all too
5) use a media editor to put the scenes and the music together, time it all so things line up accordingly as you see fit.
6) include credits and give respect and pay dews where needed else you will be flamed by everyone that sees it.
7) publish on the web.
have fun organizing it fletch;)and can cut me out other than maybe flying by and interacting in some parts of the vids.
I have way to many projects going on to undertake even something as small as this.
