chainmax: the first & last frames aren't improved with my method, also I said:

- differential motion will completely mess up with that script
- if depan doesn't catch the motion, you'll get a super-motion-blurrer

so, it won't help much with your kind of clip.

it only helps with clips that
-are not that shaky (your is shaking heavily)
-have a very short shutter speed (your does)
-have no differential motion (yours has a huge amount of diff. motion)
-had been point-downscaled by the cam (yours is better scaled -> unfortunately not that suited for my algo....)

handling your clip with my method will result in an ultra-mess: 9 frames blended into another...

also:

wouldn't it be a better idea to use somethinglike SharpResize instead of Lanczos?

I only have used lanczos for the comparision.
my method internally uses pointresize as working clip
and lanczos as estimation clip.
It was the best combination

EDIT:

the result of the video, I used to build this script:

hint hint hint....

feed it with fieldseparated true interlaced video...

hint hint hint....
