Result: encodes took twice as long, literally.

The new CRF system - for Constant Rate Factor - provides near 2-pass results in a single pass. Believe me, the guys that created the x264 encoder that's at the heart of HandBrake have been doing extensive work in video and psychovisual-perception encoding (fancy words that basically mean really complicated mathematical processing) to get the high quality results HandBrake is capable of these days.
Thanks! I was wondering if it was worth trying the 2-pass method.
