the lower the CRF value, the higher the bitrate. slowdown is due to preset changes, bitrate differences are due to AQ mode changing from AQ1 default to AQ2 default.
I found that AQ1 was giving a higher bitrate than AQ2, but I suppose it depends on source. I think AQ1 is constant while AQ2 is variable.
