Resolutions, capture rates and aspect ratios
The
resolution
(also known as frame size or display mode) of a video signal, digital image, TV screen,
computer monitor or other display device is a count of the number of pixels displayed horizontally and
vertically. For example the resolution 1920×1080 (which is 1080p) creates an image that is 1920 pixels wide
and 1080 pixels tall.
The
aspect ratio
of an image describes the proportional relationship between its pixel width and height. The
resolution 1920×1080 (1080p) is quite a bit wider than it is tall. The ratio of its width to height is 16 to 9,
represented as an aspect ratio 16:9.
AV.io 4K outputs resolutions in commonly supported aspects ratios. The table below is a color-coded legend
for interpreting the two tables of product resolutions below it:

video might be stretched, or scaled to a different size and surrounded by black letter-boxing, based on the
software and your configuration settings. Read
