I thought 'vbitrate' set the desired maximum limit - and that the
actual bitrate was variable (VBR). It was a surprise to find such a
small difference between the B and non-B cases - that's all.
Is the lavc encoding VBR or CBR? If it's CBR then yes I understand
the filesize being constant and depending only on the bitrate.
Thanks.
