Usually i make 1-pass crf encodes, but if the file is too big may i simply run the second pass with the same cmdline changing:
--crf xx --pass=1 --stats ".stats"
to:
--bitrate xxx --pass 2 --stats ".stats"

The quality from the second pass will be identical to a normal 2-pass encoding or not ?

That is normal 2pass encoding. The 2pass algorithm doesn't care what ratecontrol method the 1st pass used, as long as it's not too extreme bitrate-wise.

Thank you akupenguin for the quick reply.
I have read the "CRF translated to DABR graph and discussion" thread http://forum.doom9.org/showthread.php?t=116773 and i try to find the optimal method but i don't want to waste my time with wrong crf encodes.
