Why Key?
Keying makes only certain parts of a clip
transparent. The terms key and keying
refer to their physical counterpart, the key-
hole. This is because keying “cuts a hole” in
an image, making it transparent. The hole
is filled with another image—in this case,
clips in lower tracks of the timeline.

Video-Safe Zones
The Monitor panel displays the entire video
frame, but television monitors are likely to
crop off the outer edges of the image. There-
fore, you may need to check whether certain
parts of the image fall within the video safe
zones (Figure 9.22).
In video, the inner 90 percent of the com-
plete image is considered to be action-safe
that is, everything within that area is likely
to appear on most television screens. The
inner 80 percent is considered to be title-safe.
Because you cant afford to let any of the title’s
content be lost, the title-safe area defines
a necessary safety margin. The safe-zone
guides are for your reference only; they aren’t
added to the source image and don’t appear
in the program output.
To view safe zones:
In the Title Designer panels More pull-
down menu, select either of the following
(Figure 9.23):
Safe Title Margin—Displays guides for
the inner 80 percent of the screen
Safe Action Margin—Displays guides
for the inner 90 percent of the screen
Deselect an option to hide the safe-zone
marks in the Title Designer panel.
