• Union - output a combination of the bg and fg inputs' frame

sizes.

• Intersection - output an intersection of the /jointfilesconvert/368881/bg and fg inputs'

frame sizes. This restricts the output to the area where the

two frame sizes overlap.

range. Color channels (RGB) are not affected.

ImageAverage

This node layers images together using the Average compositing algorithm: (F+B)/2. It produces the average of the

You can also specify a different compositing algorithm using the operation control.
