Comets and Ghosting on Betamax

[QueenAllTheWay]

The sample below is taken from a Betamax recording from Nov. 91. A few people I know still recorded with Beta rather than VHS and I was sent this which in someway makes it looks better than my 1st gen VHS copy recorded in SP mode. While I did some noise reduction, I don't know how to get rid of some of the comets that appear in the "1" at the beginning of the BBC ident and the ghosting around Elton John's ear.

The footage is interlaced but not flagged as such. So when it's played back there is no attempt to mitigate the combing that you see.
SO you have a couple of choices: create a de-interlaced version from it, or keep it interlaced - for example, conversion to DVD

Ghost reduction in AviSynth:

Overlay(last, last, x=19, y=0, mode="subtract", opacity=0.1)

Try this for the comets on the 1

AVISource("Queen - Freddie Mercury Tribute BBC intro.avi")
convertToYV12(interlaced=true)
assumetff()
SeparateFields()
noisy = last
nonoise = SpotLess(last,Radt=1,blkSz=4)
diff = 10 # Difference between denoised and noisy clips
m = mt_lutxy(noisy,nonoise,"y x - "+string(diff)+" - 255 *")
mt_merge(noisy,nonoise,m)
weave()

Actually this seem to work best on your video:

nonoise = SpotLess(last,Radt=2,blkSz=16)

playing around with a Vapoursynth script
LGhost works fine as alternative to Overlay

What's crazy about your sample is that I didn't even realize until now of the added AI Upscale on Elton's incredibly detailed face which overall really works. nice job

I used CodeFormer which sometimes can produce nice results, but sometimes it's a real mess. (especially on low quality sources)
