Adjusting A
Chroma Key
Adjusting the
Width, Softness,
and
Low Sat
values is a bit of an art form. Usually,
the best way to do this is to start with the
Width
value first.
1.
Click on the
Width
slider and drag it right or left to adjust the value.
You can also adjust values by clicking on the numeric value and dragging the
mouse up or down. Typing in a numerical value also works.
2.
Set the
Width
value to the lowest value that still keys out the majority of the
blue.
Keep an eye on the blue stripes on the middle balloon. Notice that if the range
is set too high the blue stripes disappear. It’s okay to have rough edges at this
point.
3.
Click on the
Softness
slider and drag it right or left to clean up the edges of the
balloons.
Because of the blue stripes in the balloons, it is difficult to get clean edges
without removing the edges of the stripes. Try to get the edges as clean as you
can.
4.
Click on the
Low Sat
slider and drag it right or left to adjust the value if you
are having difficulty getting soft edges.
Keying In A
Framestore
You should be able to achieve a good key. The difficult part is keeping the blue
stripes in the balloons. Now let’s see what the balloons look like with a different
background keyed in.
1.
Double-click the Los Angeles skyline picon (Figure 4.7) in the
Bins\Stills\Manmade
bin to load the framestore into the
Preview
bus.

2.
Click the
FS
button that corresponds to the Los Angeles skyline framestore on
the
Program
bus.
