Copies the bounding box from the A input onto the B stream. The bounding box defines the area of the frame that Nukesees as having valid image data. The larger the bounding box is, the longer it takes Nuketo process and render the images.
Some Nukeoperations, such as a merge, can cause an expansion of the bounding box area because Nukedoes not know that the extra area is going to be black or another constant color. Often, you can fix this by copying the bounding box from one of the inputs to the resulting image, thus cutting off the extra area.
