Identifying safe areas
The Video Preview window displays the entire video frame data. However, most television monitors do not
display all of this data. Previewing the video on a television monitor is the only way to verify what frame
information will display. You should also note that individual television monitors vary in what they display.
While there is no substitute for previewing on a television, safe areas are a good method of estimating the
extent of the masking.

Safe Areas.

Click the Overlays button to toggle the safe areas display on
or off. The display shows two areas:
• The safe action area is the frame area that is visible on a

Tip:
To customize safe area sizes, choose Preferences on the
Options
menu, and on the Video tab, enter the Action safe
area
