Viewing safe zones Television sets enlarge a video image and allow some portion of its outer edges to be cut off by the edge of the screen. This is known as overscan. The amount of overscan is not consistent across television sets, so you should keep important parts of a video image, such as action or titles, within margins known as safe zones. You can view safe zones in the Monitor window's Source view, Program view, or both. ![]() To view safe zones in the Monitor window: In the Monitor window menu, choose Safe Margins for Source Side or Safe Margins for Program Side. Choose either menu item again to remove the corresponding safe zones from the Monitor window. To change the dimensions of the safe zones: 1 In the Monitor window menu, choose Monitor Window Options. 2 For Action-Safe Margin and Title-Safe Margin, type new values representing the percentage of the full Program or Source view window not included in the safe zones. Click OK. Editing Video > Using the Monitor window > Viewing safe zones |
