System Overview

• The high resolution Background layer has the lowest priority. This layer visually

appears “behind” all other PIPs, keys, and the DSK. The system can transition

between two background sources — both of which must be at native projector

resolution.

• A PIP layer appears “over” backgrounds and “under” the DSK and LOGO. Effects

include mixes and wipes, linear moves and resizing, adjustable aspect ratio,

borders, drop shadows and soft edges.

• A Key layer also appears “over” backgrounds and “under” the DSK and LOGO.

Key effects include luminance keys, split keys (key alpha and fill), reverse key

(key on background), and color key (graphics).

• Within the mixer, layer B has priority over layer A, but you can change that priority

as desired with the

Swap Z-Order button.

• Up to eight analog inputs and up to two SD/HD SDI inputs can be scaled to

produce PIP or Key images.

This section illustrates the many (but not all) combinations of image effects that you can

create on the ScreenPRO-II. Please note:

• In the following illustrations, the specific layers used in creating each effect are

labeled (e.g.,

PIP A, PIP B).

• The symbol ↔ denotes a PIP or a key that can transition. For example, PIP A ↔

B indicates that you can dissolve between sources within the PIP.

The ScreenPRO-II system provides two backgrounds, two scalable layers in the mixer plus

an unscaled DSK and a full screen, unscaled LOGO. The LOGO, DSK and backgrounds

are always unscaled.

This effect includes a non-transitioning background (either A or B), one transitioning PIP

and the DSK.

Important

If the DSK is in use, the background cannot transition

between A and B. This occurs because

BG/DSK Input B is

shared between the DSK and BG B.
