Operation, cont’d

A square wipe causes the preview image to appear to unroll over the program image in one of two transitions (figure 3-35):

Starting at all four edges of the screen and moving in to the center of the screen.

Starting at the center of the screen and moving out to the edges of the screen.

• A title effect produces two different effects: ECP window and ECP key.

ECP window causes a predefined box in the program image to dissolve to reveal the preview image (figure 3-36). The effect is as if the preview image were located behind the program image, and a window in the program image opens to show the preview image. When the effect ends, the preview image disappears, and the program image is again intact (see “Changing the title settings” on page 3-8 for information on defining the title box).
