1pass 2pass wtf?
 

Okay, I have made several 'good' quality movies for my guildies of several wow fights, for tips, advice, showing where we go wrong etc :)

However, I've been thinking of doing a higher quality release for general consumption, and I've seen some really high quality videos out there, clear true-black, not grainy etc.

I've done some playing around with settings on codecs, both XVid and DivX, and got a pretty good (although still a little washed out & grainy) quality job going, however, I've always used 1pass encoding, and I keep reading about people doing 1 pass and then a 2nd pass, and adding the audio to the second.

My question (Vegas 7 user) is how to do 2 passes on the same video file? As far as I can see when I go to render, I have the choice of doing 1 pass and saving the file as an AVI, is there a way to combine a second file? Or do I do it somehow in Vegas before I save the file?

this explains the 2 pass stuff and i must say it is definately worth it

each pass dusnt take all that long and you make an mp3 for the audio to get better quality (and so its not PCM compressed)

the only thing i dont get is how the first pass relates to the 2nd pass
