A background can be:
PowerScript holds the page background in a special background plane. The page you are
creating and the one that is playing on the output channel share this plane. Therefore, if
you play a title on the Program monitor while simultaneously editing another page on
the Preview monitor, the background is not displayed on the Preview monitor while edit-
ing. The Preview monitor uses the same color as the background on the Program moni-
tor. If you change the background, PowerScript remembers it, but it won't appear until
the playback stops or the playing page happens to use the same background color.

Creating a Solid Color Background

To create a solid color background:

Using a Video Signal as a Background (Using PowerScript's Internal Keyer)

Keying is the process of superimposing titles and graphics over an incoming video signal.
PowerScript supports internal and DownStream Keying (DSK).
PowerScript's internal keyer automatically superimposes titles and graphics on video that
Internal Keyer
comes in through its Video IN jack.
To use the internal keyer:
106
• A solid color
• An incoming video signal (using PowerScript's internal keyer) over which you can
superimpose a page
• A graphic (such as an imported EPS, JPEG, PCX, or GIF graphic file)
Tip
If you want to see the background while creating pages, set your system to Single-Monitor
Mode. When you are ready to playback the pages, reset the system to Dual Monitor Mode.
