Field-blending in 'Nightmare Detective' R0 PAL

[kumi]

This recent RaroVideo release has the following field-blending:

or

This is the field pattern that seems to repeat over and over... double letters are blended fields:

ab b bc c cd d de e e f fg g g h hi i i ij j k k kl l m m


Is there anything that can be done to remove this type of blending? I'm totally new to field-blending. In fact this is the first DVD that I've noticed it on. Thanks to anyone that takes a look. :)

It seems to be:
3,3,2,3,3,1,1,1

With, in that example, the first 3 missing.

Thats the pattern that fits the sample size you posted.

[kumi]

Sorry, burfadel: what do those numbers mean, exactly?

EDIT: here's another way to see the field pattern:
- --> Blended
| --> Original
~ --> Duped

|-|-|-|~|-|~|-|~-||~-||~-

Am I wrong, or was the original source 24fps? If so, Why the heck does this PAL DVD have blended fields?

It seems like a "perfectly normal" case of fieldblended normconversion. You get this when the PAL version was created from a hard-telecined NTSC source, by just pushing it through a converter box, instead of doing IVTC.

Restore24 / MRestore are your best chances to get this source clean of blends with smooth motion.

Ahhh, thank you Didée! I was unsuccessful with Restore24() (way too many blends passed through), but Mrestore did the trick.

ord = last.getparity() ? 1 : 0
leakkernelbob(ord,4,true,true)
Mrestore(dclip=last.crop(8,8,-16,-8))

This is what I get after that script + DGpulldown to 25fps:

Looks good to me. I'll run on the whole movie and see how that goes.

Were you using the "old" Restore24, or the RC1 version? - I tried the RC1 version on your sample, and there is not one single blend in the output ...

[kumi]

Thanks, I was mistakenly using the 2004 version.
