Deinterlacing-problem

[Benus_MinO]

Hello!

I have a problem with interlace in one anime, immediately come to things. The interlacing using commands such as:

DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.d2v", info=3)
ColorMatrix(hints=true,interlaced=true)
tfm(order=1).tdecimate()
LanczosResize(640,480)

I also trying something like this:

DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.d2v", info=3)
Telecide.Decimate(5)

A result of this configuration is an error, only appears on this line kanji:



I have tried to improve filters:
AAA()
LimitedSharpenFaster()


But it did not help anything. Also tried Yatta, The result worse.


I would like to ask you to help with configuration interlacing, in top sorry for my poor English.

provide a m2v sample

it is the link given in the subject

I ran it through animeivtc() in mode 1 and everything looks fine.

[Benus_MinO]

something like this?:
AnimeIVTC(mode=1, aa=2)

then looks terrible, and why I want to do this filter 4 belts after two crashes and error?

It's soft telecined. Your clip looks just fine with Forced Film in DGIndex. Is there some reason you can't use Forced Film?

Also, you have to select Yes for the field order correction on your sample clip.

For external IVTC, I used this simple script:

telecide()
decimate()

and everything was fine. I don't understand why you obtained a bad frame using that. Please try again with the field order correction.

[Benus_MinO]

I can give, but after that in megui can not detect the type of interlacing

[Guest]

Your response is unintelligible to me.

If you use Force Film, the output will be progressive, so there's no need to try to determine type of interlacing.

Benus, where are you from?

I tried something like this:
DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.d2v",info=3)
ColorMatrix(hints=true)
telecide()

Sample:
>>>http://www.megaupload.com/pl/?d=1LLRX9ZE<<<

or

DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.d2v",info=3)
ColorMatrix(hints=true)
decimate()

but here you can see the pixels around subtitles
Sample:
>>>http://www.megaupload.com/pl/?d=6UFRW8Y0<<<


and an attempt to improve the quality:

Import("C:\Program Files\AviSynth 2.5\plugins\AAA.avs")
DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.d2v",info=3)
ColorMatrix(hints=true)
decimate()
trim(2300,5000)
LimitedSharpenFaster()
LanczosResize(640,480)
Undot()

Sample:

but it does not work, you can see that in opening interlacing is not done in 100%
you have any ideas?

[Adub]

No, no, no.

What neuron2 said is this:

DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.d2v",info=3)
ColorMatrix(hints=true, interlaced=true)
telecide()
decimate()

However, when I noticed frame 564, (right after the scenechange, after inverse telecining) I tried animeivtc(mode=1, aa=0) (which you can change if you want, I was just running through it real fast), and it cleared everything right up.

In short, a good, working script is this:

DGDecode_mpeg2source("C:\Documents and Settings\DWORAA\Desktop\VTS_01_1.demuxed.d2v",info=3)
ColorMatrix(hints=true,interlaced=true)
AnimeIVTC(mode=1, aa=0)

[Benus_MinO]

Doesn't detect hints...

edit//It's allright now, but why it have 19.18fps?

[Adub]

What do you mean? Make sure that you're DGDecode line contains the "info=3" option.

You need to do ONE of the following. NOT both.

A) Enable force film in DGIndex
B) Perform external IVTC with Telecide/Tecimate or TFM/TDecimate.

I used this:


DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.demuxed.d2v")
animeivtc(mode=1,aa=2)
crop( 4, 0, -4, 0)
LanczosResize(640,480)
LimitedSharpenFaster()
dedot()
Undot()

[Adub]

So, it works for you now, yes?

If so good. But also, I would recommend this instead. It should allow you to keep proper colors when converting using xvid or x264.

DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.demuxed.d2v", info=3)
Colormatrix(hints=true,interlaced=true)
animeivtc(mode=1,aa=2)
crop( 4, 0, -4, 0)
LanczosResize(640,480)
#dedot().undot() #Try using Removegrain(mode=2) instead, like this
RemoveGrain(mode=2)
LimitedSharpenFaster()

Also, instead of undot and dedot, try using Removegrain(mode=2)

[egrimisu]

shoul removegrain and other grain removers like mvdegrain be used after limitedshapenfaste?

[Adub]

No, you are right. It should be before. No sense in having limitedsharpenfaster enhance noise. I'll edit my post.

DGDecode_mpeg2source("C:\DVD_VIDEO\VIDEO_TS\VTS_01_1.d2v", info=3)
ColorMatrix(hints=true,interlaced=true)
animeivtc(mode=1,aa=0)
crop( 4, 0, -4, 0)
LanczosResize(640,480)
dedot()
undot()
RemoveGrain(mode=2)
LimitedSharpenFaster()

How I can improve quality?

[Adub]

I don't get it. That is a pretty freakin' clean source. The only thing you can do is encoder wise, such as increase reference frames, b-frames, bitrate, etc.

Frankly I think, excluding encoder artifacts from that compressed clip, it is clean as can be, and any more filtering would be too much. You have to know when to stop.
