Hi

I have p4 2 GHZ (512 kb cache) and I have used this:
vcodec=mpeg4:vme=1:vhq:v4mv:vpass=1/2:vbitrate=1000:precmp=1:cmp=1:subcmp=1
for lavcopts and -sws 2, -vop scale and crop, -oac copy (frameno.avi
3pass)

The maximum fps I get encoding like that is almost 10fps. Comparing that
to 35fps of divx4 (q=5) or 45fps of xvid (me_quality=6:4mv)...

The quality differences between each three encoding techniques are
probably too small for my eye to detect so I may be wrong if I
say divx4 still shows better quality, so thats why I want to use PSNR to
compare them.
