What about the encoding speed? Someone told me that it is the 
same for each quantizer (I doubt it). And what about quant=1? I 
heard it shouldn't be used. Does this apply to 1. pass too?

And do small differences off quantizers matter for the 
estimation anyway? It doesn't encode yet, so my common sense tells 
me it will almost be the same result.
