.B vqcomp=<0.0\-1.0>
Quantizer compression, vrc_eq depends upon this (default: 0.5).
For instance, assuming the default rate control equation is used,
if vqcomp=1.0, the ratecontrol allocates to each frame the number of bits
needed to encode them all at the same QP.
If vqcomp=0.0, the ratecontrol allocates the same number of bits to each
frame, i.e. strict CBR.
.I NOTE:
Those are extreme settings and should never be used.
Perceptual quality will be optimal somewhere in between these two extremes.
Perceptual quality will be optimal somewhere in between the range's extremes.
