ntsc interlaced film to pal progressive?

[smok3]

well, here is the test klip;

http://somestuff.org/test/

and i would preffer PAL progressive out of this, my current try is;

LoadCPlugin("t:\utility\avisynth\yadif\yadif.dll")

a=mpeg2source("video.d2v")
b=wavsource("audio.wav")
audiodub(a,b)

# change field-rate;
Bob(height=576) # Separate fields and interpolate them to full height.
BicubicResize(768,576) # Resize to PAL square-pixel frame size.
ConvertFPS(50) # Convert field rate to PAL, using Blend Mode.
SeparateFields.SelectEvery(4,0,3) # Undo Bob, even field first. Use SelectEvery(4,1,2) for odd field first.
Weave() # Finish undoing Bob.

# deinterlacer;
yadif(mode=0)

where the field-rate conversion is directly from avisynth manual, any 'better' ideas? And yes, speed is a virtue.

You used the word 'film', then possibly you need to inverse-telecine it to restore progressive 23.976, then speed-up to 25fps.
In case of TV sourced material (you can find this out in VDubMod watching by frame), it is not good idea to re-interlace + deinterlace it, you'd better try MVTools (MVFlowFPS function for smooth framerate conversion) after deinterlacing original NTSC.
Here is a page with more conventional solutions for different types of material: http://www.geocities.com/xesdeeni2001/StandardsConversion-Preview-0.html
(NTSCi -> PALp is not recommended there, try MVTools)

Field blended. There's a 24p or 25p source hiding in there. Good luck getting it out. restore24, cdeblend etc - I don't know, I never do this kind of stuff.

Blending it more (using Convertfps) without trying to unpick the blending, is a pretty nasty thing to do, though sometimes there's no better solution.

FUBAR. Absolutely FUBAR.

For one, there's lot's of consecutive blendings. Bad for blending restoring scripts. Then, there are even blended no-motion fields. That's an "impossibility" for a (single] normconversion, and blend restorers can't handle such a thing.

Probably this was 23.976 film originally, has been normconverted to 25i with fieldblending, and this fieldblended 25i then has been somehow converted to NTSC again.
If this is from a "commercial" DVD, you should claim your money back.

"Let it be" is the most reasonable advice here.

i thought so, so my script can stay as it is i guess?

It's so blended, ChangeFPS might be better than ConvertFPS. It depends what you find more objectionable.

Better still, there's probably a native PAL version of this video somewhere.

Cheers,
David.

it is not just one video, there is plenty of those...., however the problem is not so evident with more colorful approaches (as opposed to this bw thingy).
