The ScreenPRO-II Controller uses a “lookahead” preview system that ensures the
accuracy of all your transitions. The “look” or appearance that you create on Preview
represents the
exact appearance of Program — after you transition the images to Program.

The illustration below represents a simple Preview-to-Program transition.
SPLIT mode is on, enabling you to have two PIPs on screen simultaneously:
Figure 6-4. Program-to-Preview Transition with Lookahead
•
In frame 1 , Program consists of a background and a single PIP.
•
In frame 2 , a second PIP is selected and positioned on Preview.
•
When CUT or AUTO TRANS is pressed, the PIP transitions to Program. Frame 3
represents the Program screen — identical to the Preview “look” in frame 2 .
•
Frame 4 represents Preview after the transition. Preview will continue to match
Program until you modify the preview image, in preparation for the next transition.
With these facts in mind, ensure that you always create the desired “next” look in Preview.
In this manner, there won’t be any operational surprises:
•
By using lookahead, you’ll always know visually what PIPs and keys you want to
transition
TO Program.
•
Conversely, you’ll always know what PIPs and keys to you wish to clear — to
visually remove elements
FROM Program.
