Then you're saying that using vqscale=3 does not encode the movie with a 
constant quantizer of 3 but instead uses an average of 3? I was under the 
impression that vqmin and vqmax limit the per-frame quantizer - is this 
correct? Or do they limit the per-macro block quantizer. If they are 
per-frame, does that mean the vqmin and vqmax settings will have an effect on 
the per-frame quantizer range it uses when specifying a constant quantizer?
