    Not sure what to do with this blended sources. It seems three frames out of five are blended.

    Do you have a better copy? If you can provide a source with separate fields (interlacing), that would make all the difference.

    Actually, this is what I captured from TV, so I don't think there is a better one available currently.

    I see three clean frames, three blended frames. The three blended frames contain two unique frames from the source:

    Code:
    A, B, C, (C+D)/2, (D+E)/2, (E+F)/2, F, G, H...
    So every six 6 comes from 5 film frames, or every 30 frames from 25 frames. That would be from a PAL to NTSC conversion.

    I don't know of any filter designed to work with this type of blending. But in theory you could reconstruct D by reversing the transform:
    Code:
    D = (C+D)/2 * 2 - C
    Similarly, E can be restored with:
    Code:
    (E+F)/2 * 2 - F
    But doing all this automatically and adjusting to changes in cadence will be harder. Maybe I'll play with it later.
