Rescuing badly deinterlaced korean dvd

[limocello]

Hello,
I have got a videofile stemming from a Korean DVD (should be NTSC).
It is a badly deinterlaced(I guess?) version of that DVD and it shows very severe frame blending.
The video seems to be encoded in progressive, it is originally a h265 file.
I uploaded a sample of the butchered video ("bad.mkv")

I have not really been able to make out a pattern, but I'm pretty sure it is:
Three full frames -> ~Three blended frames -> Three full frames -> etc. etc.
The blending does not seem to be constant, because it looks like some frames are "more evenly blended" than others and some look like they exhibit a small amount of ghosting.
I feel like the original was incorrectly deinterlaced, as these NTSC dvds should really be detelecined, no?

The original footage is shot on film and was originally released in PAL Regions on a 50i DVD. I have uploaded a sample of that as a reference for how "it is supposed to look" ("good.mkv")

I have no idea how to handle this weird pattern of full frame and blending.
Can someone help me rescuing this butchered file? Are they even rescuable?
Thank a lot for your help

I see the problem in your bad.mkv, def have 3 > 3blended > 3 going on. Have a look at this link.

If you have a good version why do you care about the bad version?

<edit>
I see. I downloaded the "good" video and although there's no blending it has lots of levels, colors, and noise problems.

I don't think you're going to be able to remove the blending in the bad video. And next time, some shots with a little more motion would be better. Especially a panning shot.

Thank you, that looks promising :)

Sadly the "good" version has much poorer image quality than the "bad" version. (well except the blending that is)

That's for a very specific kind of blending. It won't work with your source.

99 ok
100 blended

(some more might be blended but got overlooked since I didn't spot the blending)
-> I doubt anything that assumes a fixed pattern will fail.
I also doubt one can retrieve the orginal frame from those 3-4 blended frames in a row automatically. (don't think there is any ml based approach to remove blending, is there?)
