new video signals are compared, and
the signal with the higher luminance

100% output for the first half of the
transition as the new video increases
progressively to 100%, then the current
video is progressively reduced from
100% to zero in the second half while
the new video is maintained at 100%.

new video, using the wipe pattern

using the DME effect selected in the
