Best codec/settings for cartoon DVDrip

[hp78]

Using VirtualDubMod, I would like to encode some VOBs from a cartoon series DVD.

Are this settings/filters fair?
Should I use multipass?
Should I de-interlace this source?
Should I use Xvid instead?

I would appreciate your advice.

Desired output AVI:

175MB total
160kbps MP3 audio
~880kbps video

Input VOB:

File : 746 MB (687 KB), duration: 0:22:56, type: MPG, 1 audio stream(s), quality: 98 %
Video : 622 KB, 5099 Kbps, 29.970 fps, 720*480 (16:9), MPG2 = MPEG 2 (SVCD/DVD)
Audio : 54 KB, 448 Kbps, 48000 Hz, 5 channels, 0x2000 = AC3 DVM [0x80]

Codec and settings:

DivX 6
Home Theater Profile
Multipass (2 pass)
880 kpbs
Modulation: 0
Better Quality
Keep resolution
Noise reduction: Off
Psychovisual enhancements: Off
Interlace: Progressive source
Quantization: H.263

Filters:

De-interlace (blend)
Resize (Precize bi-cubic A=-1.00) 576x432

read doom9s divx and xvid guides....or use autogk.

Ok, I did my homework. Yet I have a question:

What would be the best way to apply resize and de-interlace filters to this source?

I am trying avisynth with dgdecode and decomb:

A)

MPEG2Source("D:\Temp\The Simpsons [S04xE01] Kamp Krusty.d2v")
FieldDeinterlace(blend=false)
LanczosResize(576,432)

But I got better results with this profile:

B)

MPEG2Source("D:\Temp\The Simpsons [S04xE01] Kamp Krusty.d2v")
Telecide()
LanczosResize(576,432)

Thanks fot your time.

Hi-

You don't use Telecide to deinterlace. It's the first part of the Telecide/Decimate IVTC combo. It's true that it does have FieldDeinterlace(Blend=True) built into it by default, but you might as well use FieldDeinterlace by itself if the plan is to deinterlace. And KernelDeint is a better deinterlacer.

However, you should be able to IVTC it back to 23.976fps, I think. You said the second script worked better (I can't tell the difference between the pics, as it's too bright where I am at the moment). Try adding Decimate() after Telecide() and see if you get smooth playback.

And which version of Decomb are you using? If the recent, then you probably want:

AssumeTFF().
Telecide(Guide=1).Decimate()

Read the Decomb Reference Manual for more information.

I tried your script:

AssumeTFF().Telecide(Guide=1).Decimate()

But that didn't result in a smooth playback, as you can see.

My mistake. I just found that this behaviour occurs only if LanczosResize stays before the decomb parameters.

Anyone knows the reason for that?

The actual script I'm using is:

AssumeTFF()
Telecide(Guide=1)
Decimate()
LanczosResize(512,384)

Looks promising...

Hi-

You been working on that one for more than a month now?

Anyone knows the reason for that?

Yes, by resizing first you've messed with the fields. Decomb needs them in unresized form to work its magic. From the Decomb Reference Manual (which I earlier suggested you read):

Do not resize vertically before applying Decomb. Decomb needs to see the original line spacing to properly detect combing.

Read some more and you'll come across a Decimate setting that will help give a better IVTC to animation.

In fact, due to college I had to stop this project for a month or so.

Anyway thanks for your help.
