I don't really understand the concept but it did ... SET bitrate on the 2nd pass
(gained from CRF 21 for an episode of Friends on the 1st pass) .
Funny enough , the final product flatlined @ CRF 22 ... with a correspondingly smaller filesize .
I can only surmise that buzzqw added some magic into that 2nd pass that boosts the quality.
I didn't try to make a visual comparison since it just seems opposite to the goal of
'constant perceived quality' with 'extremely variable bitrate' .
The CRF+1pass seems better suited to streaming where a constant bitrate is more important.
That said ... I'm still hunting down the perfect encode.
Thanks much nx6 and Sharc.
It's all good
