Moiré and Artifacts after IVTCing

I have a movie and a series with the same problem:

Code:
DGDecode_mpeg2source("H:\videos\sample.d2v",info=3)

tfm().tdecimate()


screenshot without the red marks:


Looking at the "separated fields" I don't think it will be possible to get rid of the moiré like pattern, but maybe somthing can be done about the artifacts introduced in those areas after IVTCing:

Code:
DGDecode_mpeg2source("H:\videos\sample.d2v",info=3)

Separatefields()


VOB sample: http://www.mediafire.com/?sharekey=1...db6fb9a8902bda

The sample comes from the series. The sample itself is 99.82% FILM, but the whole episode is ~80% FILM, that's why I used tfm().tdecimate().

Any hints? TIA!

I use telecide and decimate and get exactly the same problems in such areas. The solution with those filters, if it's a pure film source, is to get rid of the post processing and force a consistent pattern match.

If it's not a pure film source, I don't know what to do.

Cheers,
David.

Yes, it's the post processing detecting the stripes as interlacing. For Telecide, set post=0. Or use an override on that section to disable it.

it works!

I haven't tried Telecide, but tfm(pp=0).tdecimate() works fine.

thanks again!
