Strange analog interference ghosting

[Master Tape]

Not quite sure what has caused this kind of ghosting, looks more like the machine it was either recorded or captured on that left behind some sort of comb ghosting that whirrs across the screen.

Don't know what caused it. TV channel interference?
Try something like

ffms2("Example.mp4")
separatefields()
e=selecteven().bilinearresize(720,144).QTGMC(InputType=1).bilinearresize(720,288)
o=selectodd().bilinearresize(720,144).QTGMC(InputType=1).bilinearresize(720,288)
interleave(e,o)
weave()

Edit: Script above modified reducing flicker

Something like SeparateRows(3).vInverse().WeaveRows(3) will be a little sharper but leave more residual horizontal lines. Following up with QTGMC(InputType=2) or SMDegrain(tr=1, thsad=200, PreFilter=4) will remove most of that.

Another thing I tried was less sharp:

LWLibavVideoSource("Example.mp4") 
ConvertToYV24()
src = last

Spline36Resize(width, height*4) # 4x height for 1/4 pixel precision
Overlay(last, last, y=13, Opacity=0.5) # overlay so that dark bars average with light bars
Spline36Resize(src.width, src.height) # back to normal height
SMDegrain(tr=2, thsad=200, PreFilter=6)
