I had a 2 hour and 40 minute wedding on a Premiere Pro CS 5.5 Timeline. (I exported it as a QT Reference File from Final Cut Pro 7)
I added my Encore Chapter markers in PPro and went File ----- Export ---- Media.
Media Encoder opened and I set my settings the following way:
1440 x 1080 29.97 FPS
Target Bit Rat = 18.5
Max Bit Rate 20
VBR 2 Pass
When it first started encoding it said that it was going to take 8 hours.
It has taken 14 Hours and it's finally finished.
My question is,
How much better is VBR 2 Pass than VBR 1 Pass or CBR?
The first pass of this job took about 3 and a half hours. The last 11 hours was the full 2 Pass.
Would VBR 1 Pass or CBR give a good enough quality as an H.264 Blu-Ray to give to clients.
Thanks in advance

Depends what you mean by "better". Multiple passes are done to reduce the file size (by more appropriate changes in bitrate for each moment in the footage). It's not designed to change the quality of the displayed frames, though it can have a small-but-noticeable quality effect on certain types of footage (e.g. a presentation that mixes static slides with high-motion video). If you can't see the difference in your footage, and you don't care about making the smallest possible file, VBR1 will get your clips done a lot faster.
