You will probably find almost all of the video's found here, drifting video's aside, are taken from league race replays, and recorded that way. Rather than people doing things and spectators recording it with fraps or whatever.

Sorry.

this is a strange and unnatural try...serously (no offense)
what you want is 1 guy who will make the movie...
a bunch of guys with nice skins to drive
and some sort of a voice program

now, all you have to do is go to servers, with your actors, explain what you want from them, save the replay, send it to the guy who will make the movie, get some interviews with the actors, get the movie from the guy who will make it, put the interview audio files in to the movie, render it....

this is a HELL LOT OF WORK....
but at the same time - it would be nice for people to share what they usually do in LFS....how they got there and stuff like that
