    Hi all, I have a short clip captured from an old vhs in which the bottom part of the video is like moving (sorry, my english isn't good and I don't know how to describe properly), but I attached a clip
    This happened probably because at the time of the capture (more than a decade ago),I didn't had a good vhs player, neither the skills to try to fix this before capture in to the pc.
    I don't have access to that VHS tape anymore, and where I live isn't easy to grab another copy. So, is there any way to fix that? It's a short video, 1 minute and 30 seconds, and this behavior happens in the entire video time.
    P.S actually, this video was officially released in HD (and without issues of course) in a later season from the Simpsons, but I have others similar videos like that with the same issues described above, and those weren't released officially other than the VHS series released in 90's.
    Thanks in advance and have a great new year.

  2. A line time base corrector while capturing could have taken care of that. You can use QTGMC in AviSynth to reduce the wiggle now:

    Code:
    AviSource("teste.avi") 
    ConvertToYV12()
    src = last
    
    BilinearResize(720,576)
    TurnRight()
    QTGMC(preset="fast", InputType=1)
    TurnLeft()
    
    nnedi3_rpow2(4, cshift="Spline36Resize", fwidth=1920, fheight=1080)
    
    Overlay(src, last.Crop(0, 810, -0, -0), y=810) # use only the last 270 scan lines
    That leaves a little ghosting but you might consider it a reasonable tradeoff.
