Anamorphic video

Anamorphic video

Refers to widescreen video images that have been "squeezed" to fit a narrower video frame when stored on DVD. These images must be expanded (un-squeezed) by the display device. Most of today's TVs employ a screen with 16:9 aspect ratio, so that anamorphic and other widescreen material can be viewed in its proper proportions. When anamorphic video is displayed on an old-fashioned TV with a 4:3 screen, images appear unnaturally tall and narrow.
