Re: Two Pass Encoding Worth it With High Bitrates?

I may have to try 2-pass sometime to see if the extra couple hours is worth it...

As is, my file size is usually between 1.2-1.7gig.
It depends so much on the source material that it's difficult to establish any sort of general principles.

The two pass encode will always be better but it depends on the source as to how much better.

I always recommend trying something known to be difficult like 'Saving Private Ryan' if you want to make a meaningful judgement. The landing scene at Omaha Beach is a good one to compare for relative quality.

There are even a couple of very exceptionally difficult discs I've come across that in my mind produce unacceptable results regardless of the methods used. But that's beyond the scope of normal tests.
