I don't think it's so much ghosting, it's just motion blur
The main problem is those moire (or herringbone) diagonal interference lines.
It might not look too bad if you can reduce those.
Create an Avisynth script, deinterlace with QTGMC, use DeFreq Avisynth plugin for the interference, then some noise reduction
That's what I meant - those moiré lines. I already tried DeFreq but no matter what parameters I try out, it doesn't do anything noticeable at all.

defreq(fx=11.4, fy=-66.0, dx=2, dy=2, sharp=0, info=false, show=0)
Following the first defreq with another, defreq(fx=11.4, fy=0.0, dx=1, dy=1, sharp=0, info=true, show=0), will reduce some of the vertical bars. But in some shots (with the cyan titles near the start of the clip) it makes them worse. You might be able to find a few more defreq settings to remove some more of the noise. Other noise reducers I tried obliterated too much detail when the settings were high enough to remove the noise.
I am not going to promise this, but I think trying santiag(nns=4) might help a bit with the leftover patterns you hate. I doubt it will 100% clean it, but I do think it will help a bit with visibility of it. Maybe give it a try at the bottom of your script.
