Need help deinterlacing

[nurbs]

I have Carnivale season 2 on dvd. It's the PAL/UK release. Normally when I have to deal with interlaced content I use megui to determine what to do with it, but in this case it fails.

The automatic deinterlacing gives me TDeint(order=1,full=false)but when I encode using this script the video stutters aproximately every second.

I have uploded a small sample of the source here: http://www.savefile.com/files/1106472

I would be very thankful for sugestions.

It's field-blended garbage. How did you make the DVD?

[nurbs]

I didn't make it, I bought it at amazon (http://www.amazon.co.uk/Carnivale-Complete-HBO-Season-2/dp/B000EHPOMI/ref=sr_1_1/202-9884535-0015839?ie=UTF8&s=dvd&qid=1191772228&sr=1-1). The first season is all progressive so I was surprised when they released the 2nd season dvd like that.

So if there is no way to fix it, would encoding interlaced at least preserve the motion fluidity?

You can try some unblending filters. Search for "blended fields":

you can try to undo it either in an automated fashion with restore24, or manually like this:

mpeg2source("C:\forum\nurbs\test.demuxed.d2v")
tdeint(mode=1, full=false, tryweave=true)
changefps(23.976*10)
selectevery(10,?)
bicubicresize(width, 480)
replace the questionmark with a number between 0 and 9 until all blending is gone and motion is fluent.
(For the sample video I used ?=3)

The final framerate will be 23.976fps.
If you want 25fps you have to speed up the video as well as the audio

replace the questionmark with a number between 0 and 9 until all blending is gone and motion is fluent.

Is it possible that sometimes two different values produce the same or at least very similar quality?

You should check several hundred frames with both of the ones you suspect, in different places in the movie. The wrong one should pass some blends through, but if one really does look as good as another, then it probably doesn't matter.

The method works very well. Thanks everyone, especially scharfis_brain for the script.
