== Problems in film and television ==

 

Multiple aspect ratios create additional burdens on filmmakers and consumers, and confusion among TV broadcasters. It is common for a widescreen film to be presented in an altered format ([[cropping (image)|cropped]], [[letterbox]]ed or expanded beyond the original aspect ratio). It is also not uncommon for [[windowbox (film)|windowboxing]] to occur (when letterbox and pillarbox happen simultaneously). For instance, a 16:9 broadcast could embed a 4:3 commercial within the 16:9 image area. A viewer watching on a standard 4:3 (non-widescreen) television would see a 4:3 image of the commercial with 2 sets of black stripes, vertical and horizontal ([[windowbox (film)|windowboxing]] or the [[Matchboxing#Pillarboxing and gutterboxing|postage stamp]] effect). A similar scenario may also occur for a widescreen set owner when viewing 16:9 material embedded in a 4:3 frame, and then watching that in 16:9. [[Active Format Description]] is a mechanism used in digital broadcasting to avoid this problem. It is also common that a 4:3 image is stretched horizontally to fit a 16:9 screen to avoid [[letterbox|pillar boxing]] but distorts the image so subjects appear short and fat.
