Amount	Sets the proportion of each clip to be displayed. Set a floating-point value between 0 and 1 using the slider; 0 is all of the foreground clip, 1 is all of the background clip. The normal animation would be from 0 at the first frame to 1 at the last frame.
Softness	Sets the size of the area over which the pixels will be faded from the foreground clip to the background clip. Set a floating-point pixel value between 0 and 100 using the slider.
