1:4 pulldown on telecining?

[plokm]

I'm familiar with 3:2 pulldown and ivtc'ing it, but this clip makes no sense to me. It's an anime source with a pattern of 4 interlaced frames followed by 1 progressive frame. What does this say about the telecining process, and what would be the best way to ivtc it?

I've uploaded a sample (http://www.uploading.com/files/4ZN3U3FT/sample.m2v.html) (m2v), the same thing with an avs script (http://www.uploading.com/files/LFC7A88D/sample.zip.html) premade for lazy people, and a longer version (http://www.uploading.com/files/BW3NFH9K/sample_long_.VOB.html) of the sample.

Hi-

It says it wasn't telecined, but fieldblended to get to 29.97fps. You have to unblend it, not IVTC it. I'm sure there are other ways to do it, but I did it this way:

MPEG2Source("C:\Path\To\Sample.d2v",Info=3)
Colormatrix (mode="Rec.601->Rec.709",Hints=true,Interlaced=True)
LeakKernelBob(Order=1)
CDeblend()
BlendBob()
TDecimate(Mode=1)

Here it is reencoded for DVD at 23.976fps Progressive, with pulldown applied afterwards:

Thanks, I'll give that a try.

Where can I get CDeblend? I found all the other filters...
