Poor TV Broadcast VHS Upscale - Miranda - 08.04.2024

I need to upscale a VHS capture from an old 1983 TV broadcast, which has a strange moiré pattern due to poor TV reception. Any suggestions most welcome.

can't download the file,... (no permission)

Interlaced content saved progressively without deinterlacing. Confused Dodgy

hmm, what I would try.
  • vinverse2 to remove the combing artifacts.
  • crop to remove the ugly borders
  • Edefixer to fix a bit of the artifacts at the bottom
  • BalanceBorders to lessen the coloring at the sides
  • SpotLess with temporal radius 2 for the comets
  • RemoveDirt for the artifacts <- this does most of the filtering and is the reason for most of the details loss
and then maybe BasicVSR++ or SCUNet or DGDenoise

add the end one could add some grain (https://imgsli.com/MjUzODU2)

iirc. NeatVideo was good with removing such artifacts, so it might be worth a try too.

The ProRes file is interlaced - perhaps AviDemux saved it as progressive? I will check.

The download is progressive.
When overwriting the can type each frame is duplicated,... so this isn't interlaced.
