    Stop the video that you watch better, in darker areas it can be seen more clearly!

    Interesting. When I play it in Virtual Dub, I see no lines. When I play it in VLC Player, the lines stick out like the proverbial.

  6. It's just masked by the messy residual interlaced structure. When you bob-deinterlace it the interference stripes pop out.
    One can mitigate it by applying a vertical blur which however would blur the picture.

    Try something like
    Code:
    LWLibavVideoSource("2A1_t00-00.04.25.063-00.04.30.494.mkv")
    TFM()
    separatefields().vinverse().blur(0,0.7).weave()

  7. Vertically blurred but preserving sharp edges:

    Code:
    LWLibavVideoSource("2A1_t00-00.04.25.063-00.04.30.494.mkv", cache=false, prefer_hw=2) 
    TFM() # restore progressive frames
    
    emask = Blur(1.5, 0).mt_edge("prewitt", thy1=50, thy2=50).Blur(1.0)
    blurred = BilinearResize(width, height/3).Spline36Resize(width, height)
    Overlay(blurred, last, mask=emask)

  8. MiniDeen with 5x5 for YUV + mClean works but is rather destructive: https://imgsli.com/MTg3NjIz
    Maybe defreq could be used for this,...

  9. Interesting. The problem shows up clearly on a different computer. The smaller display on my laptop must have "cured" the problem via resizing.

  10. Ok, thanks everyone for the answers, I'll test and see what I get, the idea is to keep the original quality but remove those damn lines xD
