Need Help with NTSC Interlace DVD

[DigitalDivide]

I'm having problems encoding the Criterion DVD Notorious. I've tried a few different options with the MeGUI Analyze, and yet it always seems to come out a bit...jerky.
This is what I had for my AVS script.

DGDecode_mpeg2source("G:\projects\notorious\Notorious.d2v")
edeintted = last.SeparateFields().SelectEven().EEDI2(field=-1)
TDeint(full=false,edeint=edeintted)
#crop
#resize
Undot() # Minimal Noise

Any help would be appreciated.

If you want help deinterlacing you've gotta post a sample.

Are you sure the source isn't IVTC'd? Stepping through it 1 frame at a time should show a pattern - 3 progressive frames followed by 2 interlaced frames. This is very common.

Hey MiSfit,

What program should I use to step through it one frame at a time? I've encoded about 250 movies so far and this is the very first Interlaced DVD I've ever come across. It's the Criterion DVD of Notorious. I'm thinking maybe I'll just copy the whole dvd to my hard drive if I can't figure this out. But not quite ready to give up.

Still looking for some help. If I were to post a sample of the vob file how do I go about doing that? I'd really like to figure this out.

Open the VOB in DGIndex. Set a range with the [ and ] buttons. Make sure it includes a representative part of the video and has a lot of motion. Then do File/Save Project and Demux Video. You'll get a small .M2V file. You can upload that to a free hosting site such as rapidshare.de and then post the URL. The longer the clip you can upload, the better.

Okay it's uploading now. SHould be done in about 30min or so at the spead it's going. I uploaded approx 90mb.

I also get the following when I do an Analyse with MeGUI.
Progressive sections: 114
Interlaced sections: 59
Partially Static Sections: 117
Film Sections: 5
Hybrid progressive/Interlaced

Guess I can go for a jog for 30min and come back. Thanks for the help so far. I'll send the link once it's done.

Here's the link...I almost forgot lol.

As far as I can tell, it's a perfect telecine, just needs an ivtc. Was that a MeGUI hybrid script? So far, I haven't come across any hybrid portions.

Hey Foxy,

The script was what MeGUI indicated. I have no idea how to IVTC the film. After doing 200 films this is my first interlaced one. I assume I have to add something in my avs script for this? I have no idea as to what I need to include in my script though. Any suggestions?

[Guest]

Yup, looks like straight hard 3:2 telecining (it's not interlaced, at least in this section of the movie).

Try Decomb. Read the Tutorial that comes with it.

The script for your test clip could be:

loadplugin("dgdecode.dll")
loadplugin("decomb.dll")
MPEG2Source("Notorious[1].demuxed.d2v")
Telecide()
Decimate()

[DigitalDivide]

Well I tried what you suggested. I have this in my script.

loadplugin("C:\Program Files\AviSynth 2.5\plugins\dgdecode.dll")
loadplugin("C:\Program Files\AviSynth 2.5\plugins\decomb.dll")
DGDecode_mpeg2source("G:\projects\notorious\Notorious.d2v")
Telecide()
Decimate()

I tried a small portion and it still came out jerky. When I created the project file I just did in from within MeGUI. Funny how MeGUI doesn't pick this up correctly. Should I create the project file using Force Film or Honour Pull Down Flags?

[Guest]

I tried a small portion and it still came out jerky. Is it jerky on the test clip you posted? That is just fine for me. Is it jerky after encoding or when just previewing the AVS script?

When I created the project file I just did in from within MeGUI. Funny how MeGUI doesn't pick this up correctly. Should I create the project file using Force Film or Honour Pull Down Flags? Use DGIndex manually with Honor Pulldown Flags. There is no reason for this to be jerky. Get it right on the test clip first. That is perfectly fluid with the processing I described.

Also, I never heard of DGDecode_mpeg2source(). Please use just MPEG2Source() from my DLL.

Hey Neuron,

Well I redid the project file with HOnour Pull Down, then used
MPEG2Source() as you indicated. That did the trick! It works perfect now. Thanks. The funny thing is that MeGUI is the one that put the DGDecode_mpeg2source() in the script. I tried it again and it did it again. Possibley a bug in MeGUI?

[foxyshadis]

DGDecode_mpeg2source() is just a fully-qualified function name, presumably a guard in case you have mpeg2dec*.dll in the plugin folder.

And yeah, if you ever use ignore pulldown flags, or force film when it isn't close to 100% film, you can mess up the video handling (and megui's analysis). Honor at least is consistent.
