  2. 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

  4. 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)
    SetMTMode(2,4)

    SeparateFields()
    e=SelectEven()
    o=selectOdd()

    bvo = o.MVAnalyse(isb = true, truemotion=true, delta = 1, idx = 1, overlap=4, dct=1)
    fvo = o.MVAnalyse(isb = false, truemotion=true, delta = 1, idx = 1, overlap=4, dct=1)
    fco = o.MVFlow(fvo, idx=1, thSCD1=500)
    bco = o.MVFlow(bvo, idx=1, thSCD1=500)
    interleave(fco, o, bco)
    finesharp # mettre au début pour sharper les vrais détails
    dfttest (sigma=16, sigma2=16, tbsize=3)
    DeGrainMedian(limitY=255,limitUV=255,mode=5, norow=true) ## >>> to clean some dropouts but introduce some artefacts even though the weakest mode is used
    #DeGrainMedian(limitY=255,limitUV=255,mode=1)
    od=selectevery(3,1)

    bve = e.MVAnalyse(isb = true, truemotion=true, delta = 1, idx = 2, overlap=4, dct=1)
    fve = e.MVAnalyse(isb = false, truemotion=true, delta = 1, idx = 2, overlap=4, dct=1)
    fce = e.MVFlow(fve, idx=1, thSCD1=500)
    bce = e.MVFlow(bve, idx=1, thSCD1=500)
    interleave(fce, e, bce)

    #DeGrainMedian(limitY=255,limitUV=255,mode=1)
    ed=selectevery(3,1)

    interleave(ed,od)
    Weave()

    # To clean grain
    mdegrain2i2(4,0)

    # To clean chroma noise fluctuations:
    ConvertToYV16(matrix="Rec601",interlaced=true)
    separatefields()
    U = UToY().ttempsmooth(maxr=1,lthresh=150, strength=1)
    V=VToY().ttempsmooth(maxr=1,lthresh=150, strength=1)
    YToUV(U,V,last)
    weave()
    converttoyv12(matrix="Rec601",interlaced=true)

    Hi Dgicube, is the solution working?

    I currently have a similar issue:

    Click image for larger version

Name:	artefacts.PNG
Views:	117
Size:	914.5 KB
ID:	45290

    and it appear only with a batch of my 8mm tapes

  6. 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.
