Description

This filter is intended to reverse the field dominance (I refer the read to here for the best explanation of field order on the web) of PAL DV video.

My Matrox G400 TV-out outputs the top field of an avi first and then the bottom field.

But PAL DV is always stored as bottom field first and this filter reverses the field order by simply moving each line up (or down) by one line and duplicating the bottom(or top) line.

Check out this thread in Doom9 to see how it came about and to get Donald Graft's VirtualDub version.

Syntax

ReverseFieldDominance(bool shiftup) (true/false, default true)
