Some questions: 1. What should I do if on my second pass I get a bigger/smaller file size than the one I want? Do I just do another 'multipass-nth' pass with a bitrate adjustment + update log file? 2. Under what circumstances do I have to do the 1st pass again? 3. What filters do you recommend to increase quality when re-encoding? 4. How do I determine what to set 'Max bitrate' to? 5. What do you recommend for these settings: GMC, Qpix, and B-Frames and pyschovisual.
