Help with Decomb for Avisynth

[cesm23]

Hi.

I'm new to this deinterlace thing. I have some DVDs and I ripped them using
DVD Decrypter. Now, i'm planning on converting the VOBs to H.264 but
doing all the Cropping and Filtering one time only. But, i came across one
problem...when I opened the VOBs with Avisynth using:

DirectShowSource("my_file.VOB")

I discovered that it had horizontal lines. I Know it is AN Interlaced Video but
I don't want to use the Blend Fields thing on VDub, because it creates Ghosting.

Then I went and seached all the internet until I found Decomb.

My souce is an Interlaced NTSC Anime Episodic DVD (720x480). I found out
that Decomb is good for Anime, so I gave it a try...

I read the Tutorial and everything and finally created my final script which is:

LoadPlugin("C:\Decomb.dll")
DirectShowSource("my_file.VOB")
AssumeTFF()
Telecide(guide=1,post=2,back=1,hints=true)
Decimate(mode=3,quality=3)

It works, I mean, it Deinterlaces my Anime DVD, but I can see some Artifacts in some parts of the video and some blocks from time to time (that are not in the original source). Also I can see that sometimes the lines are like Zig-Zags.

I did all tests for "AssumeTFF" and that's correct.
Also, the video isn't always 3:2 PullDown...I mean, it's like it's hybrid or something...


Please, I need some help configuring this filter...it's driving me insane!

What do you think I should use?

Maybe I should just give up and use Blend Fields, right? At least it doesn't create
these artifacts.


Thanks for all the help.

Post a link to an unprocessed sample of your source material, using an area that contains the artifacts after processing. You can open the VOB in DGIndex, set a range with the [ and ] buttons, and then do save project and demux video. Upload the resulting M2V to an upload site and post the link here.

Hi again and thanks for the reply.

The things you asked I uploaded here:

http://www.megaupload.com/?d=Z5QRKSBH

It's a RAR File containing the Video, the Script File and a TXT
I made with the frame numbers and description of the errors I noticed.

Also, I verified MD5 and SHA1 for the video file, if you want
to ensure that you receive it without errors.

MD5 - 31a79adf276a51537a39d5dcebf2c776
SHA1 - 2d72e6f09d3a05ae2b4b27130f60e637e476b64a


Thank you for everything.

PS - I played the unprocessed video in Media Player Classic and it
didn't have the Interlace Lines, so I slowed down the video and found
Ghosting on it...Yet, speaking about quality, it didn't seem reduced...
So...should I use Field Blending for Deinterlacing? If so, what Field Blending
Deinterlacer for VDub or Avisynth should I use? Thanks.

OK, you can recover clean progressive frames.

First, don't use DirectShowSource(). Use MPEG2Source() from the DGMPGDec package. There is a quick start guide in the package to get you going.

Save your project with Video/Field Operation = Honor Pulldown Flags. Then use this script:

MPEG2Source("Unprocessed.d2v")
telecide(guide=1)
decimate()
