Getting rid of shimmering lines

Sereenie · Post by **Sereenie** » Fri Aug 24, 2007 11:13 pm

After having successfully tackled my temporal chroma shift problem and done most of the footage cleaning up, there is one last problem I can't seem to solve: shimmering lines. It's all over the place. The problem was already there before I started the clean up process and it's been significantly reduced, but it's still blatent enough that it can't be ignored.

I put an lossless example clip here.

You can see it in all the eyes (and eyebrows) as well as in the mouth of the second girl from the right. An in Utena's hair, in the upper right.

And here is my current script.

MPEG2Source("G:\Utena\01-07\ep01.d2v",cpu=6)
dedot()
TDeint(mode=1, mtnmode=3, blim=100,order=1,type=3,full=false,ap=35,slow=2)
mrestore(mlimit=1.6,ani=true,numr=2002,denm=5005,rr=10,dclip=last.crop(16,16,-24,-24))
Crop(6, 2, -26, -10)
BlindDeHalo3(PPMode=-1)
degrainmedian()
Lanczosresize(640,480)
fft3dfilter(sigma=2,plane=4,bw=64,bh=64,bt=0,ow=31,oh=31)
awarpsharp(blurlevel=4,cm=1)
tweak(sat=1.2)
dull = last
sharp = dull.limitedsharpenfaster(strength=200)
soothe(sharp,dull,30)
vmtoon(strength=96,sharpen=false)

All suggestions and advice are welcome...

Thanks!

I get that with some of the Inuyasha clips I use (only sometimes worse).

I'm really not familiar with Utena footage, but have you tried the SangNom bobber? I had a little success using that with Tenchi Universe clips (until my computer ate them

).

I did and got pretty good results, but it's so slooooooow... I was thinking of switching Tdeint back to it after I dealt with the rest of the cleaning up, so it would be faster.

Its from deinterlacing it, most likely. Do IVTC instead.

That's what I tried first, but when I IVTC, there's blending.

Most IVTC filters contain a deinterlacer as well. The deinterlacer runs after the IVTC. The IVTC itself does not cause blending, but the deinterlacing does. You can configure all this in the ivtc settings.

Uh, what's IVTC? And how do I use it?

I have, but that part must've slipped by me.

Thanks!

Duly noted!

Plus, something else occurred to me: my unsuccessful tries at IVTCing happened when I had that weird temporal chroma shift. Now that I managed to solve that, I haven't tried IVTCing again to see if there really *was* blending or if it was only linked to that other problem. Which I am pretty sure is the case. After all, why would I be the only person with blending in that footage?

Once again, thanks a bunch for your help!
