Fullscreen
(or
full screen
) refers to the 4:3 (1.
3
:1)
aspect ratio
of early standard television screens and computer monitors.
[1]
Widescreen
ratios started to become more popular in the 1990s and 2000s.
The aspect ratio of 4:3
Film originally created in the 4:3 aspect ratio does not need to be altered for full-screen release. In contrast, other aspect ratios can be converted to full screen using techniques such as
pan and scan
,
open matte
or
reframing
. In
pan and scan
, the 4:3 image is extracted from within the original frame by
cropping
the sides of the film. In
open matte
, the 4:3 image is extracted from parts of the original
negative
which were shot but not intended to be used for the theatrical release. In reframing, elements within the image are repositioned. Reframing is used for entirely
CG
movies, where the elements can be easily moved.
