FFT3DFilter: .avs or "Avisynth" in FFDShow?

Simple question: I'm think about the usage of FFT3DFilter in my source (it's a test script), and I've recently found out that the FFDShow has an Avisynth field itself. It has some space for avisynth scripting too.

In the case of using some filters and plugins in my .avs, where is "better" to put the "fft3dfilter()"? In my avs, with DSS(), assumefps(), audiodub() et cetera, or just in that FFDshow's "Avisynth" field (with the box checked, of course)?

I'm asking it around because I want it to be eficient (my source has the hell of a banding!) and speed (and FFt3dfilter is way too slow for my PC).

Does it have any different effect somehow?

By the way, what about the "Debanding" in FFDShow and gradfun2db()? Same here: What's better to do in my case?

Code:
vid = directshowsource("E:\episode.avi",video=true,audio=false).converttoyv12.assumefps(23.9379)
#framecount: 36978
#framerate (jerked): 23.9379

audep=DirectShowSource("E:\audio.mp3",video=false,audio=true)


audiodub(vid,audep)

FFT3DFilter()
gradfun2db()

textsub("E:\subs.ass")
Any suggestions at all?

Thanks ^^

Well, I haven't all understand because you wrote in english!
First I suggest you to use avisource and nicmpg123source. Directshowsource is only for desesperate case, you don't need it here.
Gradfun2db is a very good and fast plugin. FF3dfilter, as you said, is slow, but if you need speed you can try mvdegrain1 which offer good compromise quality/speed.

IIRC, ffdshow's deband == gradfun2db.

Effective dithering, very useful after fft3dfilter / fft3dgpu, which can both introduce / reveal banding.

The problem of using avisource is this one, that I take in AvsP:

"AVISource: couldn't locate a decompressor for fourcc WMV3, line 1"

I have CCCP codec pack installed in my system. And it comes with FFDShow. In the "Codecs" tab, I go to "WMV3" and put it on "libavcodec".

In the end, it still keeps coming with this error. Any suggestions?

I could talk to you in portuguese. Would you understand it?

Ok, let's say you want to put the FFt3dfilter (or mvdegrain1) to work on your source. Ok. What would you do? Just put it on .avs script? Or put it on AVISynth (with the box checked) section in FFDShow? What would be the difference?

Did you enable it in the VFW configuration of ffdshow?

That was causing the error. Now it's ok. Thanks.
But what about the other previous questions?

I would do it in avisynth. That's the most simple solution. I don't see how doing it via ffdshow would speed it up.

But you could try to find that out by testing.

Right.

Even the gradfun2db works better now.

One more question (it's the last one, I swear... -_-):

Now that gradfun2db is working fine, i got some, uh, "color noise" in the screen.

Please, look at the wall in the left side of the picture, behind the character (after clicking the link, click on the image again to maximize it).

[img=http://img195.imageshack.us/img195/8838/imagekbt.png]

I'm talking about the blocks with different color tones than the expected ones. It's too far from the neighbour colors... You can see it around the character's eyes too.

What should I do here? The FFT3DFilter now reveals "stripes", so I've removed it from the avs.

Is that with or without the FFT3DFilter, and is it also visible in the source?

The FFT3DFilter doesn't change it that much. Actually, this filter does some "block stripes" visible, and in some scenes, makes this "noise" stronger.

What he says.

If you want to do something about your noise/block problem, I suggest you open a new thread about the problem. Correcting something like that, that's already in the source, is hard and maybe impossible. Don't forget to post an unprocessed sample with it.

You could maybe also try an unblocking filter. But I guess the difference will be small. I also wonder how it got in the source.

Alright. Thanks a lot for the answers. ^^
