[x264-devel] CRF and VBV

[Georg Lippitsch]

Hi,

what is actually the effect of setting a CRF value when VBV is used?

I want to set a maximum local bitrate and have no other limitations for  
the stream. So, can I simply set a very low CRF (let's say, 2) and set a  
VBV as I need? Or are there any disadvantages using a low CRF? If so, is  
there any way to calculate a somehow reasonable CRF from the bitrate?


Thanks,

Georg
