function "
Range
" is active. Specify a new range
and click on "
OK
". Now you can view the new
scene in the Edit menu.
The multi-layering technique for Image Proces-
sing effects can also be applied by using the Edit
menu to activate a scene in the scene bin and then
clicking the "
Special
" button. All Image Proces-
sing effects are listed there. The effect you select
is not applied into the storyboard. Instead a copy
is made of the active scene in the scene bin with
the Image Processing effect added to it. The copy
is then identified with the extension "
SP
", "
SP 2
",
etc., as the case may be. You can carry out this
procedure any number of times.

and to the

Keep in mind:
If you change a setting for an effect
that has already been calculated, or change the
duration, or even replace the effect with another,
the effect must then be re-created. Be careful!
The Image Processing effects in detail
The following Image Processing effects are avai-
lable in the standard package:
1. Binarizer:
The scene is divided into two colors
according to brightness. With "
Color 0
" you bring
up the color box in which you select a color that
replaces the darker areas. "
Color 1
" replaces the
brighter areas. The "
Threshold
" of the transition
from light to dark can be set from 0-100%. And
you can set "
Transition
" between the two colors
from 0-100% in order to prevent "edge shimmer".
2. Color depth:
A very frequently seen effect can
be achieved with this. The number of colors in the
picture is reduced. The "
Depth
" can be set from
2-50. The "
Transition
" can be set from 0-100% in
order to prevent "edge shimmer".
Tip:
Up to 16 million different shades of color can
appear in a video image. This allows fluid transi-
tions. For each color component (there are a total
of three color components) there are about 256
possible levels.
3. Color to Grey:
Usually the video material is in
color. This effect can convert the video to black-
and-white. If you want to convert long segments,
or perhaps even the entire video to black-and-
white, then you can set the color saturation in
the Video settings menu to 0% when initially
recording the material. This might save you long
calculation times.
4. Control Color:
With this effect you can correct
the colors "
Red
", "
Green
", and "
Blue
" in the scene
(later adjustment). You can set the color from
0-200%, where 100% corresponds to the regular
color.
5. Control Image:
With this effect you can change
"
Brightness
", "
Contrast
", "
Saturation
", and
"
Gamma
".
6. CVBS filter:
This effect can be used to reduce
edge shimmer which sometimes arises when using
an CVBS (RCA) connection. This shimmer can
appear at very fine, high-contrast edges arises to
a much lesser extent or not at all when using a
SVHS connection. Using the filter causes a weak
blurring of the image. The filter should therefore
only be used when absolutely necessary.
You can set the "Strength" from 1-3.
Tip:
With a CVBS connection the signals for
brightness and color, which are normally separate,
are mixed. This causes considerable loss in
the video bandwidth, especially for color. The
"
CVBS filter
" reduces the video bandwidth and
thus reduces the extent of the undesired effect
described above.
7. Doubler:
This effect blurs the scene by
overlaying the image with itself so that a light
colored shadow appears.
8. Dynamic range:
This effect is used to limit
the extent of brightness and contrast. This
makes possible interesting estrangement effects.
Experiment a little with the settings! The preview
offers a good approximation so that you don't
have to make time-intensive calculations. All
image information is retained under "
Type
".
