my source is a ntsc dvd and the interlaced pattern is 2 progressive frames and 4 interlaced frames.

here's a vob-sample. any help is appreciated.

It's field-blended.

A brute-force way (which looks horrible) is:

MPEG2Source("E:\tmp\VTS_04_1.d2v")
AssumeTFF()
telecide(post=2,vthresh=20)
decimate(6)

As you can see, deinterlacing field-blended progressive video is not a good idea.

You may be able to get better results using unblending filters.

thanks, but I scrapped that dvd. couldnt get a decent copy of it.

but could you take a look at this other one I also have?

I tried:

LoadPlugin("g:\stuff\progs\dgindex\dgdecode.dll")
LoadPlugin("g:stuff\progs\decomb\decomb521.dll")
mpeg2source("D:\movie\movie.d2v")
Trim(0,164445)
FieldDeinterlace(full=false)
Crop(6,2,-12,0)
LanczosResize(640,346)


but it really wasn't too good. also if u know any filters that can make this movie look better that would be nice.
