Convert PAL DV to Standard PAL

Field dominance simply refers to which field is displayed first in time, i.e., temporal order. Swapping fields means interchanging the fields of a frame. Swapping fields will reverse the temporal order, but it will also interchange each pair of lines, putting them spatially in the wrong position.

There are methods of reversing the temporal order without reversing the spatial order. Two of them were discussed in this thread.

Your capture card is simply putting each field in the "wrong" field of the output frame. That creates incorrect temporal and spatial order that can be corrected by swapping fields.
