In fact, the image was purposefully over-scanned to be sure no black edges would exist. So, manufacturers would slightly zoom in the image so that it would fill the frame. (Viewers did not realize that the resolution of a video image was fixed, even if the monitor size increased.) They did not want to see any black edges around their image. (This delay between saving and purchasing consumer goods was one of the driving factors in the creation of credit cards in the early 1960’s.)Īfter saving for that length of time, consumers wanted the biggest picture they could afford.

It would take the average family two years to save enough money to purchase a black-and-white set and up to eight years to purchase a color television. Since this was before the days of credit cards, people needed to pay cash for a TV. The problem was that, in those days, televisions were really, REALLY expensive. The higher the voltage, the brighter the phosphor would glow. In those days, images were “painted” on the back of a phosphor-coated glass picture tube energized by a high-voltage beam of electrons causing the phosphors to glow. The origin of these indicators dates back to the earliest days of television. Changing them won’t get you anything extra and runs the risk your audience won’t see your text or composites completely in the frame.Īnd, if Include 4:3 Safe Margin is checked, the Monitor displays a 4:3 center-cut frame with additional safe zones indicated inside it for those shows that need to create both a 4:3 and 16:9 version of their program. NOTE: While you can vary these percentages, my recommendation is to leave them as is. Premiere also has additional settings, at the bottom of the Wrench menu, called Overlay > Settings, that allows you to change the size of the rectangles, measured as a percentage of the total image subtracted from the edge of the frame. Here’s what they look like, by default, in Premiere: two rectangles with small hash marks that indicate the horizontal and vertical center of the image. Premiere calls them “Safe Margins” and you enable them from the Wrench icon in the Program or Source Monitors. You’ve seen these rectangles in your video, but what are they and why are they there?įinal Cut Pro X calls them “Title/Action Safe Zones” and you enable them from the View menu in the Viewer.
