Horizontal Rainbow lines on VHS videos

[QueenAllTheWay]

Quite common on VHS video (I took this snippet of from a BBC documentary), but anyway to reduce or remove these rainbow horizontal lines?

try something like this:

LWLibavVideoSource("sample.mp4")
# remove chroma fluctuations
ConvertToYV16(matrix="Rec601",interlaced=false)
U = UToY().ttempsmooth(maxr=1,lthresh=150, strength=8)
V=VToY().ttempsmooth(maxr=1,lthresh=150, strength=8)
YToUV(U,V,last)
ConverttoRGB32(matrix="rec601",interlaced=false)
#### CCD COLOR DENOISING :
LoadVirtualDubPlugin("C:\Program Files (x86)\virtualdubmod1.5\plugins\Camcorder_Color_Den oise_sse2.vdf", "CCD", 0)
CCD(30,1)
converttoyv12(matrix="Rec601",interlaced=false)
mergechroma(last)
fft3dfilter(bt=3,sigma=19,plane=3,degrid=1,bw=16, bh=16, ow=8, oh=8)
fft3dfilter(bt=3,sigma=19,plane=3,degrid=1,bw=16, bh=16, ow=8, oh=8)

Horizontal rainbows is all you're worried about?

That's the least of your problems. Doesn't look like a piece of BBC to me. That mp4 is one ugly piece of work. You don't have a sample of the original capture?
