Deinterlacing badly mastered dvd?

[DeeGee]

Seems like my "2010 - The Year We Make Contact" is for some completely unimaginable reason interlaced so that the some frames are progressive and some frames have their other fields in the next frame...
So is there any deinterlacers that can keep the progressive frames as they are and try to combine the fields from the two frames when needed?

Sounds like simple telecining. Just search for Ivtc. TIVTC and decomb are filters for this problem. :)

Ah, ok. Thank you.

Haven't got lot of experience on deintelacing as most dvd's in the pal land are progressive...

If it's PAL, then you want to apply a field matcher and not full IVTC. You can use Telecide() or Tfm().

We call the phenomenon a one-field phase shift. If you have a field sequence like this (where each letter refers to a field of a progressive picture):

A A B B C C D D ...

that aligns in frames like this:

A B C D ...
A B C D

then if you lose a field (due to an editing cut) so that the sequence is now:

A B B C C D D E ...

it now aligns like this:

A B C D ...
B C D E

Now you have combed frames even though the material is really progressive. The alignment of the fields has become off by one. This can be repaired by rematching the fields with a field matching filter.

I used the basis of RTFM so i only used tfm(). :readguid: :D


PAL Cases:


1.) PAL, no decimation (just field matching)

mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")


But thanks for the notice anyway.
