there is the multiple captures techniques for that, see here
Otherwise i tried various filters, but it don't work that great, i know it work better with interlaced fields, so upload the original file, maybe there is a chance*** DIGITIZING VHS / ANALOG VIDEOS SINCE 2001**** GEAR: JVC HR-S7700MS, TOSHIBA V733EF AND MORE -
like i said for the streaks the multi captures technique is your best option
To clean chroma artefacts and some dropouts lines use this:
SetMemoryMax(1200)
SetMTMode(2,4)
AVISource("George short.avi")
assumetff()
# To clean chroma noise (desaturation), light:
ConvertToRGB32(matrix="Rec601",interlaced=true)
separatefields()
LoadVirtualDubPlugin("C:\Program Files (x86)\virtualdubmod1.5\plugins\Camcorder_Color_Den oise_sse2.vdf", "CCD", 1)
CCD(10,1)
weave()
converttoyv12(interlaced=true)

In the George short.avi (original) file, the streaks that extend all the way across the frame only happen on odd fields. One solution would be to bob it; replace the bad field with a motion estimated version created from the two adjacent bobbed fields, and then re-interlace.
