Safe area is a term used in television production to describe the areas of the television picture that can be seen on television screens. Older televisions can display less of the space outside of the safe area than ones made more recently. Flat panel screens, Plasma displays and liquid crystal display (LCD) screens generally can show most of the picture outside the safe areas. The use of safe areas in television production ensures that the most important parts of the picture are seen by the majority of viewers. The size of the title-safe area is typically specified in pixels or percent. The NTSC and PAL analog television standards do not specify official overscan amounts, and producers of television programming use their own guidelines. == Title-safe area == The title-safe area or graphics-safe area〔''(EBU Recommendation R95: Safe areas for 16:9 television production )''. September 2008. Accessed 2013-03-18.〕 is, in television broadcasting, a rectangular area which is far enough in from the four edges, such that text or graphics show neatly: with a margin and without distortion. This is applied against a worst case of on-screen location and display type. Typically corners would require more space from the edges, but due to increased quality of the average display this is no longer the concern it used to be, even on CRTs. If the editor of the content does not take care to ensure that all titles are inside the title-safe area, some titles in the content could have their edges chopped off when viewed in some screens.〔David Pogue, ''iMovie HD & iDVD 5: The Missing Manual''. Sebastopol, California: Pogue Press/O'Reilly (2005): 355〕〔Jon Bounds, John Buechler, & Jen DeHaan, ''Windows Movie Maker 2: Zero to Hero''. New York: Friends of ED (2003): 209. "Try to keep your words inside the title-safe area—a few inches in from all edges of the screen. Graphics placed outside the safe area may not display properly on a television screen."〕 Video editing programs that can output video for either television or the Web can take the title-safe area into account. In Apple's consumer-grade NLE software iMovie, the user is advised to uncheck the QT Margins checkbox for content meant for television, and to check it for content meant only for QuickTime on a computer.〔David Pogue, ''iMovie HD & iDVD 5: The Missing Manual''. Sebastopol, California: Pogue Press/O'Reilly (2005): 186.〕 Final Cut Pro can show two overlay rectangles in both its Viewer and Canvas; the inner rectangle is the title-safe area and the outer rectangle is the action-safe area.〔Lisa Brenneis, ''Final Cut Pro 3 for Macintosh''. Berkeley, California: Peachpit Press (2002): 596.〕 In the illustration, the green area is referred to as the "title-safe" area (note that these colors are for illustration only and do not appear on the television screens). This area will be seen by all television screens, no matter when they were made, unless the user has modified the settings. The term "title-safe" originated from the fact this is where it is safe to display text such as lower thirds or full-screen graphics listing information such as telephone numbers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Safe area (television)」の詳細全文を読む スポンサード リンク
