Japan's Hi-Vision originally started with a 5:3 (= 15:9) ratio but converted when the international standards group introduced a wider ratio of 5 + 1 ⁄ 3 to 3 (= 16:9). Many digital video cameras have the capability to record in 16:9 (= 4 2 :3 2 ), and 16:9 is the only widescreen aspect ratio natively supported by the DVD standard.
The term "SmileBox" is a registered trademark [4] used to describe a type of letter-boxing for Cinerama films, such as on the Blu-ray release of How the West Was Won. The image is produced by using a map projection-like technique to approximate how the picture might look if projected onto a curved Cinerama screen. [5]
Academy ratio 1.375:1. The Academy ratio of 1.375:1 (abbreviated as 1.37:1) is an aspect ratio of a frame of 35 mm film when used with 4-perf pulldown. [1] [2] It was standardized by the Academy of Motion Picture Arts and Sciences as the standard film aspect ratio in 1932, although similar-sized ratios were used as early as 1928.
Still frames are also called freeze frame, video prompt, preview or misleadingly thumbnail, keyframe, poster frame, [2] [3] or screen shot/grab/capture/dump. Freeze frames are widely used on video platforms and in video galleries, to show viewers a preview or a teaser. Many video platforms have a standard to display a frame from mid-time of the ...

Framing square, or steel square, or carpenter's square, or roofing square Originally designed for timber framing, a framing square is made from a single flat piece of metal or polymer to a standardised design with a long, wide blade and at 90° to that a shorter, narrower tongue. It can also be used for measuring lengths and for calculating angles.
Common lines made using a speed square include perpendicular cut marks and Angles definition of an angle for roofs, stairways, and decks. The tool uses a 0° reference. This means when a board is squared off the tool reads 0°. The angle derived is actually a complementary angle, for example a 22.5° angle is actually 67.5°. The sum of the ...
The square has many uses, including laying out common rafters, hip rafters and stairs. [1] It has a diagonal scale, board foot scale and an octagonal scale. On the newer framing squares there are degree conversions for different pitches and fractional equivalents. Framing squares may also be used as winding sticks.
