Screwed Pal->NTSC material. Any way to improve?

[Maximus_G]

Hi!

There is a video, which obviously was shot in PAL - and then - was corrupt by encoding it to an NTSC DVD.

I've tried numerous avisynth techniques to improve it, involving rePal filter and others, but i just can't find the right way of dealing with such a problem.

Google didn't help (
Can't find a proper topic here either.

Here's the example:

Can it be improved (at least)?..

[scharfis_brain]

loadplugin("c:\x\vinverse.dll")
loadplugin("c:\x\tivtc.dll")

avisource("bad-pal-to-ntsc.avi")
vinverse()
tdecimate(mode=2, rate=25)
bicubicresize(width, 576)

This script will blur the combing, knock out the double frames and resize it back to PAL-proportions.

However, you'll end up with 25fps which are blended and rather blurry. You may try to interpolate it up to 50fps by motion interpolation...

The result is very acceptable - thank you scharfis_brain, you helped me a lot - again! :)
