I've done 3 pass encoding using Gordian Knot and can't see big diffrence compared to 2 pass encoding. What advantage does 3 pass encoding have?

After 3 pass encoding, I found movie.avi. What is it for? Is it ok to delete it?

Here is the log from GK..

We can certainly draw clues from the context of your request, but why not go ahead and mention the software you're using and anything else you might think relevant to sorting out your problem?

Until we get the details, here is a brief answer to the pass number question: you won't notice the difference unless you study both versions with a magnifying glass :D

I personally tend to do a 3rd pass when I have a lot of time and want to get the absolute best (theoretical) quality possible ... and that's rare ;)
