weird interlaced artifact in tfm

[OvejaNegra]

i have weird lines in my videos after TFM. The rest of the picture looks ok. This happens ramdom (in some frames, not in all the video).

look at the pictures.
this is the script:


mpeg2source("C:\BCK\On Process\aika x\p.d2v", idct=0,info=3,cpu2="0000xx",showQ=false)
colormatrix()



interp = separatefields().EEDI2(field=-2)
px = tdeint(type=2,edeint=interp,mode=2,full=true)

tfm (mode=0,pp=1,d2v="C:\BCK\On Process\aika x\p.d2v",display=false,cthresh=5,slow=1,blockx=8,blocky=8,MI=32,clip2=px)

tdecimate (mode=3,cycleR=1,hybrid=2,denoise=false,mkvOut="tiempos.txt")

crop(8,0,704,480)


#end

the frames are not interlaced (so tdeint is not working). Just the field matching.
This happens in aika R 16 (many frames) and trigun (some frames).
Disabling post processing in DGDEC does not helps
Maybe is just a sequel of forced interlacing. Maybe not.
PD: the aika DVD (the one in the pictures) is from japan.

Thanks.

A video sample (m2v) of the buggy sequences would be best and I'd recommend looking into AnimeIVTC (but without a sample... no advice!).

[OvejaNegra]

how upload the sample please?

[Comatose]

Use DGIndex with the [ and ] buttons (start and end respectively) and then File -> Save Project and Demux Video and upload the m2v.
In any case, it's probably your settings which are causing this... I have the OP sequence (post IVTC) and I don't see the artifacts you have in the first two screenshots (though, it's the credit OP - but you have them in other screens as well).

Try simple TFM().TDecimate() and see what happens. If it works well, put your settings back one by one till you find the one that's causing you problems.

+1
Also try VinVerse() after TDecimate()

colormatrix has a parameter for interlaced video...

[OvejaNegra]

WAIT!!!!!!!!!

Scharfis, you are right! killing colormatrix solves the problem.
Now what should i do? The interlaced parameter support mixed progressive/interlaced frames or colormatrix must be used after TFM???

This is new for me.

Sorry for the english

[Adub]

Colormatrix(parameters,interlaced=true)

That's all you need.

[OvejaNegra]

Merlin: Yes i know, that, thank you. But i think that is for pure interlaced video. My DVD is anime, some frames are interlaced, and some others not. It's an hybrid DVD.
interlaced=true wont damage the progressive frames?

Thanks for the help

[Adub]

No, it won't hurt the progressive frames. Everything will work fine. I have used it on probably hundreds of different source files (episodic dvd's and so on) and one hundred percent clean with the interlaced flag set to true.

[OvejaNegra]

Thank you. That solves my problems. Thanks a lot.

Now i think i have to reencode something...................
