+Quantizer compression, vrc_eq depends upon this (pass\ 1/\:2) (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.
