I'm in pal region so have not any experience with ntsc interlaced material.
I've just bought BRYN TERFEL's concert in Amsterdam DVD.Then I started learning
by reading many posts and guides about this subject.
As TBarry says to business(we're missing you Tom).
I was seeking with this simple script in vdubmod
mpeg2source("D:\BRYN_TERFEL\BRYN_TERFEL.d2v")
crop(18,0,698,476)
LanczosResize(640,356)
SeparateFields()
LumaFilter(25,1.2)
...and I've watched that in odd frames.
there was a distortion in first line.
Then I've tested SampleDiscDVD that I've got from Nic's page
with almost the same script and the distortion line was in even frames.
AviSynth_300104.exe
tested with xvid decoder,divx,and ffdshow.
It's probably a newbie post so my apologizes in advance.
Anyway I would like to mention that LumaFilter(),included
in MPEG2Dec3.dll by MarcFd is the only filter for avisynth
I know which loops are a line loop(forgive me if it's not the right expression),
it doesn't work with row size but with the whole frame size.
So I've done a quick test making a version as a plugin working
with row and adding modulo after each line,and the problem
disappeared.
Where is the problem?
1)Is my simple script wrong?
2)Is there another bug I can see in LumaFilter?
3)Is there a bug in SeparateFields() with YV12 inputs?
4)Maybe another problem I can't see.
Thanks in advance.ARDA
