6.10 VLight5 Color
For this example you should choose an approx.
5 second long scene of you driving past a row of
trees or walking in a forest.
It is important that the scene contains a stark
contrast between the foreground and back-
ground (e.g. trees through which you can see
the sky, a stretch of water or a meadow).
Even a fixed scene can be used as long as the
appearance of refracting rays of sunlight in this
video footage would theoretically be possible
and look realistic.
Insert the scene in the storyboard, open the
Transition Effects menu and insert the “VLight5
Color” effect.
After clicking on the “Full Size” function (if
applicable), turn your attention to the effect
options. First of all, load the predefined setting
“Radiant White” from the archive.
After loading it from the archive you might al-
ready see some light rays.
If the light rays are too strong or too weak, you
can adjust them using the “Beam Density” func-
tion provided under the “Effect” option.
Note: If you do not see any light rays at all, it is
highly likely that the “active color” (accessible
from the “Effect” option) is not correctly set.
(This color setting is not used to configure the
color of the light ray but instead the color values
in the picture at which the light refracts. If you
choose a bright color value, the system looks for
this color value in the picture and generates a
light ray that originates from the position of the
light source at this point in the picture).
For this example, select a color that matches the
color of tree trunks so that light rays are formed
at the edges of the tree trunks.
Now change “active color” slightly but make
sure that you do not select a color value that
does not appear in the picture or else you will
not see any light rays at all.
Generally the light grey values work best since
these are present in most pictures. Since,
however, the optimum settings depend on the
particular footage being used, it is impossible
to provide a universal solution that could be ap-
plied to any scene.
You should also configure the following settings
for this example:
“Ambient Light” 0%, “Beam Range” 70%,
“Beam Density” 10%, and “Falloff” “On”.
