  1. And how might I effectively remove it without too much damage? I have these horizontal, scrolling lines in a few different recordings and cannot figure out how to rid of them.

  2. It's regular interlaced video. You see these scanlines and comb artefacts when you watch the video on a progressive monitor (PC) without deinterlacing it.
    So you should just enable the deinterlacer of your SW player. It's a setting in your player (probably called deinterlacing or bobbing)
    When you watch this video on your TV, your TV should do the deinterlacing automatically and you should get a perfect picture.

    If you still see some lines you would have to apply some extra filtering using Avisynth filters for example, something like
    Code:
    QTGMC()
    QTGMC(InputType=2)
    vinverse()

  3. It's definitely not interlace lines I'm seeing. The lines are scrolling, moving. They are there even after QTGMC

  5. Hum bars. Defreq() can reduce those types of lines.

  6. Yep, I missed it. It's some sort of TV channel interference maybe, or interference through the cabling. Requires some more processing......

    I've fiddled with this one a bit but cannot seem to find a spot to place the box on the spectrum that even minimizes it

  8. Then you could try
    Code:
    AssumeTFF()
    Cnr2()
    QTGMC()
    QTGMC(InputType=2)
    dfttest(sigma=20)      #adjust the sigma

    This will remove a lot of it:
    Code:
    SeparateFields()
    DeFreq(fx=0.0, fy=57.5, sharp=19.2)
    Weave()
    You can probably use it again (maybe multiple times) with a slightly different frequency to remove more.

  10. I appreciate your help jagabo. I will continue to test this method and see if I can get a somewhat clean result
