Avisynth MT (for multiple cores, and its fucking awesome!)

Looks like I've got some playing around for the next couple of days.

Yes, but my point was, how do you know whether or not a filter works? Sure, you can try them all one by one, but that will be quite time-consuming. Thus, my question wondering if documentation would (should?) specify that the filter works on all the image.

that i don't know and from what i do know, there is no documentation of what works and doesn't. When i do my testing i'll be documenting what works with what modes.

So far decimate() works... very well

Hopefully this will help in my future endeavors.

I managed to get 7-8fps with this script! It used to be 3fps.
An 800mb +/- 20mb was done in 2 minutes!!!

SetMTMode(2)
MPEG2Source("C:\AMV_Project\FireFight\VOBs\K_S_Vol1\K_S_Vol1.d2v", cpu=6)
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\FluxSmooth.dll")
TFM().TDecimate(mode=1)
MT("""Deen("a3d",4,10,12).TFM().TDecimate(mode=1).vmToon(strength=164).Crop(8,0,-8,-0).UnDot().Tweak(cont=1.1,sat=1.05,bright=0, hue=.2).TemporalSoften(4,4,8,15,2)""")

Woops! Made a mistake with the TFM(), I've got it in twice.

There, 946.51mb of uncompressed output took- 2:37.
At approx 7 or 8 fps.

This test, without MP()

MPEG2Source("C:\AMV_Project\FireFight\VOBs\K_S_Vol1\K_S_Vol1.d2v", cpu=6)
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\FluxSmooth.dll")
Deen("a3d",4,10,12).TFM().TDecimate(mode=1).vmToon(strength=164).Crop(8,0,-8,-0).UnDot().Tweak(cont=1.1,sat=1.05,bright=0, hue=.2).TemporalSoften(4,4,8,15,2)

3-4fps , 4:52.
946.51mb

MT is AWSOME!

I've tried different SetMTmodes 1-6, they all took the filters but didn't make much of a speed difference in the processing. Only Mode 1 made a slight difference, going up to 9 fps once in a while, but only made about 5 seconds difference.
I'd stick to mode 2 because it goes frame by frame rather than 1/2 frames.

Well, there are some things that mode 2 an do that mode 1 can't, so =/
