Each of the safe areas defines the likelihood that an object placed in the safe area will be
visible in the on air broadcast. Figure
3-10 and the following table indicate the location and
meaning of each of the safe area frames.
When you are creating a scene, it will be the output device’s (i.e. television) resolution
format that determines the size and shape of scene format. This ensures that all of the
objects placed on the scene appear in the appropriate places on air. Consequently, the size
and shape of the safe area frames is determined by the television format that you select for
your scene using the S
CENE F ORMAT property field (see “SceneFormat” on page 4-8 ).
