1. Although I am using it always, I guess veryslow is not needed here
2. No 2-pass, I don't see blu-ray restriction kind of distribution as the main problem here,
3. I guess no.
I guess you want to make sure that enough bits are spent in any case.
What I did in such cases was simply limiting qp decisions and test for that on the most complex scene.
Release any bitrate restrictions, decrease qpmax as much as you see it driving bitrate up.
Maybe you see going below --qpmax 30 will definitely force bitrate upwards.
Then step back, meaning increase qpmax again a few ticks --qpmax 36 ?
till you feel safe giving enough headroom.
Now you shouldn't get too low rate decisions anymore, so hopefully safe from harm.
