This section illustrates the many (but not all) combinations of image effects that you can
create on the ScreenPRO-II. Please note:
•
•
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.

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.
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.
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 .
