    Yes, I see now. In the given script, AVISynth's maintains the order from the original fields, not the resulting fields from SeparateFields().

    My confusion came a video I was converting a long time ago where I was doing something which, although much more complicated, boiled down to:

    AVISource("file.avi")
    SeparateFields()
    SelectEvery(2,1,0)
    Weave()

    That does not reverse the field order. AviSynth automatically restored the original order of the fields.

  3. Newbie help please on a similar problem.

    A few years ago I copied all my Panasonic DV videos from the 1990s to my PC as avi using Windows movie maker in the original quality (approx 13GB per hour of video).

    At the time the recordings were made I set the Panasonic camera to 16:9. However reading this thread indicates it was an illusion of 16:9 and black bars were superimposed on the 4:3 picture.

    As a result all my 16:9 recordings have black bars at the top and bottom when viewed on a 16:9 monitor (and look a bit squished top to bottom as well).

    Seeing as this thread is 13 years old, is there an upto date step by step guide of how to remove the black bars and view the videos correctly, as I originally hoped when I made them 20 years ago.

    I attach a screen capture below.
