You see the balloons over the black background in the program monitor
(Figure 4.5).

Cleaning Up
The Key
The edges of the balloons are a little fuzzy at this point, so use the
Width
,
Softness
,
and
Low Sat
sliders (Figure 4.6) on the
Keyer Settings
panel to clean up the key.
Figure 4.6: Width, Softness, and Low Sat Sliders
Following is a list of the functions of the
Width, Soft,
and
Low Sat
sliders:
Width
Increases or decreases the amount of color taken out of
the signal. If too much blue is removed from the
image, lowering the range value compensates.
Softness
Affects the edges of the objects. Increasing the softness
smooths the edges of the objects you are trying to key.
Be careful not to increase the
Softness
value too much,
or it will cause your image to become transparent.
Low Sat
Used to limit which colors are being removed from the
video signal. It specifically affects colors that are
closest to white, so by increasing the
Low Sat
value in
this tutorial, you no longer key out the lightest shades
of blue. In practical use, the
Low Sat
value is usually
tinkered with to remove “sparklies” caused by uneven
lighting in a live environment.
