If I use 1280x720 resolution everything seems to be ok but if I resample to 640x360 this happens

Looks like a VBV issue, not a bug per se but bad behavior.

May I suggest using Gabriel's latest 2pass VBV patch? Note: also helps 1pass.

Have you tried twopass encoding instead? CRF isn't known to play that well with VBV from what I know...

2-pass works obviously :)

I've experienced such artifacts here and then, but they only happenend with some builds... very strange behaviour. I'll keep an eye on this

CRF worked very well, at least now as I encoded BP with a 2 MBit cap. Thank you for your efforts, to implement VBV!
