Weird Ghost Effect when deinterlacing(vob+caps included)

x_rex30 · Post by **x_rex30** » Wed Jun 07, 2006 11:17 am

Everytime I try to deinterlace this I get this weird ghost effect..

Here it is interlaced..

after trying to deinterlace..

anyone got any script recommendation? I have the vob so you can test something out. I tried fixing this with koop but I nor him could figure this out. Maybe there is nothing I can do and I'm going to be stuck with this ghost effect.

I can't even see what the problem is. After the deinterlace, your second frame looks fine.

No it does not.. do you see in her brown hair where it gets whitish? If I showed you some of the sex scenes in the anime you can see the problem a lot clearer.. but I don't think I can show those..

for awhile I couldn't really see any difference...but the hair on the left side of the screen is definately more pale.

if you haven't already, try messing around with back(int) and/or vthresh(int)
(just randomly guessing at a solution)

[if you don't know, back(int) compares the current frame with (int) previous frames (not sure if this is used with telecide() or decimate()) and vthresh(int) sets the sensitivity of whatever is determining if a frame is interlaced or not...useful for getting rid of interlaced mouth movements]

Nor do I really want to see them. But I can see what you're talking about now. If it were me, I would either ignore it, or just remove that frame. Depending on how much of a problem this is, that might be more trouble than it's worth though. You should probably post your script too. Good luck getting it fixed, sorry I can't really help.

There's no problem, or you have chosen a bad example. As you can see, the third frame is brighter than the first, and the (de-)interlaced frame is inbetween. Don't look at the single frames, watch it at the original speed. Beside this, no matter what deinterlacing method you choose, a deinterlaced frame looks always not as good as a progressive frame because the half of the information has to be interpolated.

There is no problem whah?? I've deinterlaced over a hundred DVDs before and I've NEVER ran into this problem before so I do see a problem. Like I said the better examples are in the sex scenes but I can't show that. I guess I'll try getting more help at the doom9 forums.

As others have said, its just due to the deinterlacing, and also you have still failed to post your script.

Strange. As I judged that you have no problem I was sitting behind a LCD. And there is no problem. Picture 3 is brighter than picture 1 and even 2. So it looks like a sequenz that gets brighter. Now, behind a CRT, picture 3 has the same brightness as picture one, only picture 2 has brighter colors. I've checked at my second monitor, a LCD, and again is picture 3 the brightest.

I think what causes the different looks at CRT and LCD displays is responsible for your problems. But I have no idea what it could be. Beside this, as Zarxrax said, post your script.

OK, I'm back.. here is the script..

Code: Select all

loadplugin("C:\Programs\Programs\dgmpgdec140\DGDecode.dll")
mpeg2source("E:\BIBLE_BLACK_NEWTEST_VOL1\BIBLE_BLACK_NEWTEST_VOL1.d2v")
ConvertToYUY2(interlaced=true)
TomsMoComp(1,5,1)
Bicubicresize(640,480)
Crop(4,0,-4,-0)
AssumeFPS(24)

I've tried other ways of deinterlacing here
