    Hello,

    I was wondering if it's possible to fix video that has odd 'bob' to it, like it was improperly deinterlaced (I think so) without access to original recording.

    The video that shows what I am talking about: https://www.youtube.com/watch?v=dpU9R4p5AdQ

  2. Something like this in AviSynth helps a lot:

    Code:
    LWLibavVideoSource("Bio Channel_ Leslie Cheung (Full).mp4") 
    v1 = SelectRangeEvery(3,1,0).QTGMC(InputType=1, preset="fast")
    v2 = SelectRangeEvery(3,1,1).QTGMC(InputType=1, preset="fast")
    v3 = SelectRangeEvery(3,1,2).QTGMC(InputType=1, preset="fast")
    Interleave(v1,v2,v3)
    QTGMC(InputType=1, preset="fast")
    The original video on the left, fixed on the right...

  4. It's an odd deinterlace. It looks like it was bobbed but instead of the usual 60 fps video with the frame bouncing at each frame, it's 30 fps with a pattern three frames up, three frames down... If it was the usual type of bob you could use a single QTGMC(). But since it has the three frame pattern it required splitting it into three video, fixing each of the three videos with QTGMC(), re-interleaving them, then a final fix with QTGMC().
