No, I was being slightly simplistic/vague in my description sorry to
confuse. I think that padding to 16:9 on a frame by frame basis is what
is wanted, the principle is what I was after, i.e, get one filter
(aspect, padding) to dynamically alter its parameters, frame by frame
based upon frame rate metadata extracted from each frame.
