I have found an easier way. There is a deinterlace effect called "Spacial field swap" that does the trick for the most part. Still, some sections have jerky motion instead of the jaggies like a field order reversal has. I suspect the field order is not swapped within a frame but swapped between frames so instead of this:
1a+1b, 2a+2b, 3a+3b, ... ..it is this: 0b+1a, 1b+2a, 2b+3a, ... Field sapping only results in this: 1a+0b, 2a+1b, 3a+2b, ... It least that is what it appears. I'm looking for a solution to this.
