Decomb not working

[slarke]

helo guys,

I want to ask something on my VOB video, I demuxed it on DGDecode and some lines appeared on it, I used Decomb dll but the lines still there. I play the VOB (source) on MpcStar and the lines not there. Can anyone help me about this?

Here are the screenshots
(The lines on the DGDcode are on the eyeglass)

Thanks

Pictures are next to useless. If you want us to help, provide an untouched sample from the VOB source, 10 seconds with steady movement. Open the VOB in DGIndex. Scroll to a suitable place. Use the [ and ] buttons to isolate a small piece. Then File->Save Project and Demux video. Upload that to MediaFire and provide the link.

The reason I ask for a sample is so we can learn what you have. Maybe you don't see the interlacing when the movie is being played because it's being deinterlaced. Or maybe your TV set is an old CRT.

Nothing you've said proves Decomb isn't working. If you only see small amounts of interlacing, maybe all you have to do is to reduce the VThresh so fine combing is picked up.

Also, please post your full Avisynth script. You may have erred with it.

Your script loads decomb.dll, but I don't see a statement that executes it.

I include now the statement for the decomb.
Sorry for the mistake

Since you're using AutoGK, please post its log so we can see what it decided.

However, AutoGK can't handle this kind of a mess. It's blended and it also looks to me as if the fields themselves are slightly interlaced (or aliased) and no regular deinterlacer can handle this.

It's been telecined and then blend deinterlaced. I tried this:

Yadif(Mode=1)
Vinverse()
SeparateFields()
SelectEvery(4,0,3)
Weave()
SRestore(omode="pp3")
Decimate()#From Decomb
#TDecimate(Mode=0,Cycle=15,CycleR=3)#from TIVTC, maybe better.

But Vinverse didn't clean up the interlacing or aliasing or whatever it is very much. Maybe a dedicated anti-aliaser is called for. The 'real' framerate is supposed to be 23.976fps. You'll have to do this one manually as no all-in-one program, no matter how good, can do it. And your problem has nothing to do with Decomb.

Yes, the video is encoded interlaced but contains progressive frames. It was poorly deinterlaced before you got it. I'd start with:

PointResize(width, height/2)
nnedi3_rpow2(2)
BicubicResize(width/2, height)

Or this will clean up the DCT ringing a bit:

SeparateFields()
Merge(SelectEven(),SelectOdd())
nnedi3_rpow2(2)
BicubicResize(width/2, height)

Then deblend.

Good ideas both. I especially like the second one. Now why didn't I think of that?

Thanks guys for the help . .
