overscan | My Assignment Tutor

About title-safe and action-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 kind of cropping is known as overscan. The amount of overscan is not consistent between television sets, so you should keep important parts of a video image within certain margins, in areas known as safe zones. Safe-zone margins represent the percentage of image dimensions not included in the safe zone. You should always design from one edge of the frame to the other, because computer monitors and some television sets may show the entire frame. The conventional action-safe zone is 90% of the width and height of the frame, which corresponds to a margin of 5% on each side. Keep important visual elements within this zone. The conventional title-safe zone is 80% of the width and height of the frame, which corresponds to a margin of 10% on each side. Keep text that you intend for the audience to read within this zone. Compositions with a frame aspect ratio equal to or near 16:9 have two additional center-cut safe-zone indicators. The center-cut indicators show which parts of a 16:9 composition may be cut off when the image is shown on a 4:3 display. Such cropping is a concern when creating images for high-definition displays that may also be shown on standard-definition television sets. By default, the center-cut action-safe margin is 32.5% (16.25% on each side), and the center-cut title-safe margin is 40% (20% on each side). Note: The center-cut safe-zone margins are only shown if the frame aspect ratio for the composition is equal to or near 16:9. Safe zones and grids in Composition panel A. Grid B.
