Improperly deinterlaced footage: rescueable?

[jasper-isis]

Long story short, I'm looking at an unreleased MEP track that's covered with jaggy lines. It's as if the editor decided to slow down the entire track in Premiere without unchecking "deinterlace if speed < 100%."

At this point, the track can't be redone with this problem corrected. So is there anything I can do on my end to fix this? Is there perhaps an avisynth filter that will reverse the false deinterlacing?

So far the only solution I've come up with is a coverup, i.e. using awarpsharp to thin the lines and make the jagginess less noticeable.

Nope, you're screwed.
You could try the TIsophote filter, and see if it helps any.

Something you might want to TRY is to Seperate().SelectEven() and then try various resizing methods back to the full size. EEDI2 may be a good resizing filter to use after for that.

Thanks for the help. I decided to go with SeparateFields().SelectEven(), followed by EEDI2 and then some additional cleaning. It's not perfect, but at least now there aren't distracting jaggy lines everywhere.

You can try SangNom(..) either.

The source for my last AMV had the same problem, and I have tested SangNom and TIsophote. I still have the test files, and the result looks the same. I'm not sure why I decided to use SangNom, I believe it was faster.
