Dealing with NTSC-interlaced

ookzDVD · 8th April 2002, 05:02

Dear forum,

I have no problem ripping all my DVD which have proggresive format,
all the result is nice and smooth

But when I come with interlaced format, that makes me mad

mostly my NTSC-interlaced format I've found is from the "adult" DVD

So, ne1 here experience with the NTSC-interlaced format which
come from the "adult" DVD, which de-interlace method should I
choose to get the best result ?

Maybe some background about the source of the film before it
transfered into DVD is important. I believe the source of the
"adult" DVD is different from the "regular" DVD since the
"adult" DVD is not played in the theater

Thank you.

Quite frankly, when I do adult DVD's I take the quick and dirty method:

Code:

SeparateFields()
SelectEven()
BicubicResize(320,240,0,0.5)

These films are usually quite long and I use the rather small size to make sure that I can get as much as possible into one CD.

Otherwise when I'm dealing with pure interlaced video I use this script

Code:

smartDeinterlace(2,10,true,false,true)
#depending on source some noise reduction may be in order
BiCubicResize(x,y,0,0.5)

I usually put one level of noise filtering before the resize and the rest after. x&y I take from GordianKnot to get best size. The parameters for smartDeinterlace is almost standard, except the threshold 10, which I have lowered from 15 to catch as much interlacing effects as possible. Sometimes it is too low and then I raise it, but usually 10 will do just fine. I also use blend=false to force interpolation, something which I find gives a better result, as there won't be any ghosting.
