Replacing blended frames by MVTools restored

[D3C0D3R]

hi! i ripped some crappy dvd and tried to restore blended frames - it is not double blend from IVTC them have pattern, but very strange (not 3:2)
I use some code of Cdeblend to detect them and replace by frames given MVFlow, using ScriptClip function but for some reasons result is crappy.
Can anyone suggest scpirt that doing this job properly.

PS. Speed is no matter.

>>If you post an example clip

ok, here it is small sample

it has blend frames - i wanna detect it and replace by given me MVFlow frames
i dont wanna post my script - it very ugly

Hi D3C0D3R,

If you post the script you're using, then people can look at it and suggest what might need changing. If you post an example clip, showing the problem you're trying to fix, then people can analyses it and give you suggestions how to process it. But without either of these things, there really is no useful way to answer your question, which is probably why no one answered. :)

Difficult case. 24p was blend-converted to 25p ... not with "full blending" like "ConvertFPS()" does (blending all frames with sliding linear weighting), but rather with "partial blending" like BlendFPS(aperture=~0.25) does.

Basically, each original 12-frame-sequence

A B C D E F G H I J K L

has become

A B C D E EF FG GH H I J K L


You'll surely have big fun with restoring that. :D

I guess the ideal way for them to have done 24p to 25p would have been AssumeFPS().

SRestore(24) (http://avisynth.org/mediawiki/Srestore) is your best bet with this kind of material. Use AssumeFPS(23.976) afterwards to keep NTSC compatibility.

Srestore is neither designed to, nor can it handle restoring consecutive blendings with sliding weightings.

Basically it's a job for RestoreFPS (by mg262), but IIRC that is laid out for fully linear sliding weightings ala ConvertFPS.

For the case presented here, there is no out-of-the-box tool available.

^ how would one subtract E?

maybe I'm missing something obvious, but why not attempt on the original source with untouched fields ?

thanx for explaining what they do ...
yeah )). i tried to write script, i use search, i tried script again, i used search again and again - fail. so i post it here.

because the original fields contains such rubbish blending by itself :((

I guess they shouldn't to sell people such crap :mad:

^ usually the worst of the blends come at scene changes :( truly wish i could fix those...but since you have 1 sort of clean frame before and a SEPARATE clean frame following the blended one...nothing to compare to to UNBLEND that particular frame.
