• Transition

This setting specifies the sharpness of the

shadow‘s edge. A low value generates a

“hard“ shadow, whereas a higher value gives

the impression of a soft, diffuse shadow.

6.30.5-3 Ghost
Foreground objects appear only as a shape,

having no color of their own.

One setting has to be made:

• Brightness

The structures of the foreground object are

replaced by shading between black (0%) and

white (200%). When set to 100% the fore-

ground object is invisible.

6.3.5-4 Beaming
The “Beaming“ effect can only be used in

association with a fade time (fading in or out),

because a certain period of time is always

required to execute beaming. With this effect,

foreground objects are faded in or dissolved

over the length of a selectable graphic from

the imagepool. If a suitable image or pattern is

chosen from the Casablanca‘s image pool it is

possible to simulate, for instance, the effect of

a person “beaming“ into the scene, as if from a

spaceship. This is where the effect gets its name.

There are three settings:

• Select Effect

In association with the “Beaming“ function,

the “Effect“ button refers to the selection of

a suitable graphic. All Casablanca‘s available

graphics are stored in what is called the

“image pool“, which allows any software

product to make use of the graphic from other

software products.

For instancehe owners of “Video SpiceRack“

software will find that all the graphics from

that product are also available under Bluebox

World, in addition to graphics pre-defined in

Casablanca.

Beaming causes the foreground objects to

be faded either in or out along a graphic‘s

brightness contour. The direction of the

movement can be specified with the “Mode:

positive/negative“ button.

Border width

If the graphic is to be given its own character

in the form of a border around the graphic

structure, then this slider must be set to a value

greater than zero. The larger the value set here,

the wider appears the edge surrounding the

presently active part of a graphic.

Select Color

The color of the border can be specified with

the aid the familiar color selection box. Any

archived color is also available. The alpha

value indicates how transparent the border is

to appear.

6.3.6 Special features

The “Special features“ allow the image position

of individual foreground objects to be corrected.

Two modes can be used:

6.3.6-1 Move Rectangle

If the foreground object is not located at the

correct position in the video, it can be moved by

this function.

There are three settings:

• Use

Activates or deactivates this effect.

• Source Area

A rectangle (whose position and size can be

freely selected) precisely encloses the area of

the front video image that is to be moved.

• Destination Area

The area selected under “Source Area“

can be moved to any desired location in

the foreground video. The background

video appears at the original position of the

foreground object.

6.3.6-2 Mask Rectangle

The “Mask Rectangle“ function allows either

an external or internal foreground region

to be selected. This function is therefore

particularly suitable for covering border areas

of the foreground video so that, for instance, a

Bluescreen wall that does not fill the image can

be provided with a border, or so that a specific

object can be covered.

Note: In contrast to“Select Area“, the edges of

these image regions can, for instance, be given

soft transitions to the background (“Select

Alpha“), or image effects such as “Aura“ or

“Shadow“.
