How to remove a "Twittering effect"? (changed the word "Jelly" in "Twittering")

Well, I know that is a weird name but I wouldn't know hot to tell it in another way...:p

Ok: the source is a DVD anime. I am satisfied with the cleaning that i made and the deinterlacing process.

Here it is a sample of my video: about 7 seconds. It's mostly static apart some movement of the mouth and the head turning in the end.
If you watch it closely or better, frame by frame, you will see a strange global movement (I called it a "jelly effect" but I don't know if it's already been addressed with some other name) particuarly over the hat of the boy. This strange "noise" is present even in the original DVD.
I used the Dup() filter which it eased a little but I could only use it with very weak parameters otherwise I would have lost a ot of "small mouth movements".

Any ideas?

That's not noise. That's twittering. The most likely reason for that would be your deinterlacer screwed up with the field matching. That's the only reason I can think that happened.

And you seem to be a fansubber. I am sorry, but we can offer you no more assistance.

Is that so? I have searched the "Rules" and could not find any mention of not helping a fansubber... As far as I could see, if the source was obtained legaly - and the poster states that it's a DVD, then all is well.

No? Am I missing something?

Yes. I do own this DVD and yes I'm a fansubber but I cannot see anything in my post against the rules. I'm only try to having a good quality dump of this series and I feel to be at about 80% of the quality I want.
Backing to technical discussion, I just decripted the vob file on my hd. I opened with dgindex and saved the .d2v file selecting the "Honor Pulldown" flag. The analysis of the files told me that the field order is 99.7% film. I decided to process the deinterlacing anyway and used the MeGui analyzer. Megui suggested me to deinterlace in this way:

DGDecode_mpeg2source("filename.d2v", cpu=4, info=3)
tfm(order=1).tdecimate()

The result is good, I don't see any artifact except the twittering that can be seen in the example.

Being 99.7% film I tried also to "force film" and then again loading into avisynth but the twitter effect remained.

When I try to look at the plain DVD (i.e. in VLC) this effect is still present.

Consider that the original quality of the DVD is not so wonderful and that it was mastered from a poor source anyway with a lot of noise that i could fix with a lot of temporal denoisers. Just think that in many "key frames" you can see the scotch tape that joined different parts of the original film!

If could be of some interest I put here the rest of the filters but I already tested that they are not in any way responsible of the twittering effect.

crop( 4, 0, -4, 0)
bicubicresize(640,480,0.333,0.333)
undot()
Temporalsoften(4,8,8,mode=2,scenechange=10)
Convolution3d("animelq")
FluxSmoothST(10,15)
Dup(threshold=1.0, blend=true)

you will see a strange global movement ... is present even in the original DVD

It almost looks like the camera is shaking... So I thought you can try Depan or Deshaker for vdub; I played around with it and it looks a bit better, but maybe you can tweak it some more



AVISource("v24sample.avi")
mdata = DePanEstimate(range=8)
DePanStabilize(data=mdata, cutoff=0.5, damping=0.5, mirror=15, blur=30, method=1)
