Bluebox World summary
Bluebox World consists primarily of the
following components: one is the Bluebox World
program, while the other consists of several
individual Bluebox World effects for special
purposes. All the components of the Bluebox
World package are identified in the lists of the
transitional and long-term effects under the
name “BB <Name of the effect>“.
5.1 The Bluebox World program
The Bluebox World program (“BB Bluebox
World“) is a transitional effect. This means
that two scenes are always needed in order to
execute a Bluebox effect. Bluebox World joins
the two scenes optionally in the form of a scene
dissolve or in the form of a scene overlay. In this
case “overlay“ is initially to be taken literally,
because the second scene in the storyboard (the
scene on the right) initially entirely covers the
first scene (the scene on the left).
Only when specific color, brightness or
saturation values in the second scene are
selected with the aid of one of Bluebox World‘s
many selection tools, and made transparent in
an appropriate way, does the image content
of the first scene appear under the remaining
components of the second scene.
The result achieved in this way can then be
refined, modified or extended by means of a
large number of effects.
5.2 The individual Bluebox World effects
In addition to the program itself, the Bluebox
World package also contains a variety of indivi-
dual effects for special purposes:
5.2.1 BB Change Chroma (Image Processing)
Replaces a specific color within a video scene by
another, freely selectable color.
5.2.2 BB Separate Chroma (Image Processing)
Divides the video scene into two color regions, a
region with freely selectable color and a region
that contains all the other colors. The color
saturation for these two color regions can be set
independently over the range from 0 % (black
and white) up to 200 % (intensive colors).
5.2.3 BB Mask Rectangle (Image Processing)
Places a colored rectangle or a colored frame
with a freely selectable transparency level over a
video scene or over a section of the scene.
5.2.4 BB Move Rectangle (Image Processing)
Shifts a freely selectable section of a video scene
to a different position.
5.2.5 BB Copy Rectangle (Transitions)
Copies a freely selectable section from the
second scene in the storyboard to any desired
position in the first scene.
