PowerScript is a video C haracter G enerator ( CG ) that uses the PostScript language to
image characters and artwork on the video screen. PowerScript generates high-quality
video suitable for broadcast and high-end productions. The unit includes an internal
keyer, which allows you to combine graphic and text objects with moving video without
the need of an external mixer or switcher. PowerScript also provides a key-out signal that
you can use with external switchers.
Defined Work
Components
PowerScript uses the concept of Projects, Pages, and Objects to help manage your work. A
project is any defined collection of work—such as title credits for a video production, or
text overlays for a specific video. Every project consists of one or more pages . Pages nor-
mally consist of one or more objects . One project page might contain, for example, a
movie title, another might contain a cast of characters, and yet another might contain
other movie credits. Any given page can contain hundreds of objects, and any given
project can contain numerous pages.
You can create pages that are larger than the screen on which they appear. This gives you
the ability to do
rolls and crawls by scanning (or, scrolling) across the page.
Graphics
You can create basic graphics (such as lines, rectangles, squares, ovals, and circles) using
the PowerScript menus. Graphics can use a full range of colors, transparency, and shadow
attributes.
If you have a computer platform, you can create EPS, PCX, JPEG, and GIF graphics using
various software applications.
Graphics can be input to PowerScript, combined with other graphics or text, and imaged
on a television screen.
Because PowerScript interprets the PostScript language, you can easily use clip art and
font collections in PowerScript productions. For detailed instructions and additional
information, see “Using Graphic Files” on page 134.
Objects
The elements you use on-screen with PowerScript are called objects . Objects can be inde-
pendently positioned, deleted, altered, and managed on the screen. Types of objects
include text, basic graphics (such as rectangles and circles), imported graphic elements,
and clock elements (which show date and time).
Transitions
PowerScript offers a wide variety of transitions (such as dissolves and wipes) that you can
use to artfully switch from one project page to another.
Independent or
Integrated
You can operate PowerScript as a stand-alone device, or you can integrate it with a com-
puter platform. In either case, you can generate graphics and characters using Power-
Script’s keyboard and/or mouse pointing device.
You can connect PowerScript to a Macintosh, Windows, UNIX, Amiga, and other com-
puter platforms. The connection can be made through a serial (RS-232) connection or an
Ethernet network.
With PowerScript Communicator you can easily control as many as 10 different
PowerScript units using a PC/Windows-based software application. See the PowerScript
Communicator manual for full details.
