i've finished to code a MMX SSD. it's faster, but i don't know how much,
because i used avisynth as test env. i can send it to you when you want

Of course, but i'm still not good enough to do blind SSE2 coding ;)

I'm going to take a look at VDub's frame detection...
i could code a clipped sad c function too, to see if it's better than a dumb
sad
in my copysame filter i used a very accurate algo, who is really good to
detect
movements vs noise, but it's far too "sensible" to do detect scenes changes
:(
