[MEncoder-users] divx v's x264

[Alex Samad]

Hi

I have been running some test of re encoding my dv files I have taken of
a panasonic DV camera.

I have encoded to divx and to x264, it seems like the x264 files are a
little bit bigger. and the quality (visual only) seems to be about the
same


both are 2 pass
here is the divx 
mencoder -really-quiet
-vf scale=::::::qpal,hqdn3d=2:1:2,pp=de,uspp=5,harddup
-af volnorm=1
-ovc lavc

here is the x264

"../src/video/Dimitra/wedding-2008.02.28_13-11-32.avi" -idx

I have left the x264 in an avi file.
8467432 wedding-2008.02.28_13-11-32-divx.avi
8470152 wedding-2008.02.28_13-11-32-x264.avi


Am i doing something silly ? I was under the impression that x264 was
meant to give smaller files.
