BTW, you should try with vqscale=2 on the first pass and see if that works well, rather than vqscale=5. The latter will encode the whole first pass at very low quality so it probably won't estimate complexity well.
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
lower quant will be slower, as more bits must be encoded
Hmm. What about an option to drop headers, vlc etc encoding for 1st pass? it's enough to do the MV search and quantization, as we only want the statistics, don't need the actual bits. Counting the required bits (sth like: total_bits+=vlc[n].length) is far easier & faster than doing put_bits()... but it may mean many if()'s so it's maybe not as good idea as i thought 5 mins ago :) its planed ...
