material). The degree of sharpness can be set from
1-8 with the "
Strength " control. The preview does
not do full justice to the result, so you should
experiment beforehand with a shortened version
(Edit/Copy, Trim) of the scene you would like to
correct.
21. Solarize: The video is strongly altered with
this effect. The original colors are ignored and
new colors are created that are dependent on the
brightness. Black is replaced by blue, gray values
are converted to orange, yellow, green, cyan, and
even blue where the very brightest image areas
were. You can sometimes see similar images in TV
science programs or in crime movies as so-called
"heat images". Hard transitions may lead to shim-
mering edges, especially for VHS or when using
the CVBS connection.
The effect "
CVBS filter " can be used to alleviate
this (before or after.)
You can set the "
Saturation " from 0-100%. The
higher the percent number, the more color the
image has. For 0% you have a black-and-white
picture.
Tip: False colors are frequently used in science to
highlight small differences in brightness for the
human eye. The human eye can distinguish only
about 100 different levels of brightness, but about
100,000 different colors.
22. Spread:
Here you create a "shimmering"
image. This is achieved by distributing the pixels
within a circle (which you set with "
Step " 1-10)
containing the original pixel.
23. White balance: In case recording has led to
erroneous white matching resulting in white and
gray surfaces that look wrong but the color is OK,
you can specify the location and size of a rectangle
with the button "
Reference Color
". Then the co-
lor fault within the rectangle is averaged and the
deviations in the entire image are canceled out.
Note that only light color faults can be improved.
You can turn a red surface into a gray one, but the
effects on the rest of the image are extreme (color
distortion).
In the case that there is no colorless surface in the
image, then a color correction can only be done
with the effect "
Control Color ".
24. Zoom: A defined image area can be zoomed
in. Under " Position " you give the location and
size of the rectangle area. Under "
Zoom In
" and
" Zoom Out " you specify the start and end time of
the effect (up to 12 seconds).
5.9 Titling
Titling functions much the same as if it were an
Image Processing effect. Titling in Casablanca
Prestige is actually done as a picture-editing
effect. Instead of a "filter”, digital text is added to
your video.
Titling has two menus:
The settings in the "
Titling
" menu correspond
closely to those of the image processing
effects menu. You can read the corresponding
description there for information about functions
such as
Insert, Delete, Range, Preview, Single
image, Calculate, and Scene .
After you have selected a desired title effect, and
perhaps set further
Options in the field to the
right of the effect list , you must first Add the
effect into the storyboard. You can then enter
the Text Entry screen by clicking on the button
"
Enter/edit Text " below the effect list.
(

) In the panel above you see the names of the
selected title effects and the number of pages (e.g.
1/3, 2/3, 3/3 ). To the right of the page numbers
you see two arrows with which you can move to
the previous ("<") or the following (">") page.
If no following page exists, then clicking on this
button causes a new page to be added after the
current one.
To the upper right you can see the name and the
size of the selected font.
