The source material for the encoding is lossless, and the last thing that I 
want to do is use a higher bitrate because youtube will downgrade uploaded 
flash videos with a higher Filesize:duration ratio, I think that the other 
videos which doesn't have noticeable artifacts were encoded by youtube using 
a diferent quantization type.
