hi

i think the graphs look really good and i am thinking of making some myslef
to show how the multi-thread/slice version compares to the single-threaded
encoder.   by settings the -q switch does this make the encoder encode to a
specific psnr? and then you just look at the size of the resulting file to
see the bitrate?  bits/pixel simple calculated from the file size / total
pixels   (sounds a stupid question now ive wrote it)

does everyone agree this is the best way fo comparing the encoders?

many thanks

Tom
