Effect Mode parameter DMX value = 100
This effect creates transparency in video content based on the change in pixel color from one frame to the next. Modifiers
1 and 2 use the color difference between the current frame and the previous frame to derive an alpha value for the output
frame. Modifier 3 scales the color of the current frame to provide the color of the output frame.
•
Modifier 1:Scales RGB values of the previous frame; from 0 = maximum to 255 = minimum scaling.
•
Modifier 2:Derives an alpha value from color difference between current frame and the result of modifier 1. DMX 0
to 127 act to make darker colors transparent, with DMX 0 resulting in maximum transparency. DMX values 128 to
255 act to make bright colors transparent, with DMX 255 = maximum transparency.
•
Modifier 3:Scales the RGB values of the current frame to provide the output RGB values. DMX 0 provides the
brightest output RGB values. DMX 255 = the darkest output RGB values
