Again, speed Question...

[cmw]

Hey there!

I'm encoding my video with 640x272 (lanzcos resize), using Automated 2-Pass with Turbo, Motion Search 6 and VHQ 1 (and all the other stuff suggested in the Guide on the main site).

I've got an Intel Centrino 1,7 Ghz, which should be plenty of muscle (no prob playing games with 2,4 Ghz recommend spec at maxed out settings), 1 Gig Ram.

On First pass, I get ~15 Fps, on 2nd 8 Fps.

This really seems just a little slow to me. I'm using MeGui build 2116 (march 22nd) as frontend (and xvid_encraw (the megui-patched version from squid).

Some comment?

Did you use some exotic filters like denoisers, which version of xvid use did you enable qpel,gmc. I think is that completly normal, becouse 1.7GHZ is not much powerfull, i don't know that centrino which instructions have.

1.7 is a fairly high end centrino, probably equivalent to ~2.6 P4, and includes up to SSE2, so it's not that it's a weak processor. The filters in the script (ivtc+resize, and anything denoisers megui added) slow it down quite a bit, but it's still not complex enough to justify the extra time a lossless encode, so you just have to live with it.

Try loading up the xvid after it's done into virtualdub and recompressing it from there, and set to fast recompress, you'll see how fast you can encode with no filters. (Don't keep the output, of course.)

Hmm, I'm confused.

So I set to Fast Recompress... do I have to set the Codec Options aswell? (I just chose Xvid from the Codec list, but I didn't configure it, however the output seemed to be equal quality than the input).

I got up to 40-45 fps then. The confusing thing is I don't apply any special filters at all.

This is the AviSynth Script used:


mpeg2source("F:\DVD\Biancas\Nicht auflegen\VTS_01_1.d2v")
#blank deinterlace line
crop( 0, 72, -2, -72)

LanczosResize(640,272) # Lanczos (Sharp)
#denoise


Is it possible that just Resize and Crop take such insane amount of Power away?

Here are the other settings:

Thanks for your help btw =)
