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.
AV.io HD generates a list of the following possible resolutions for your capture application to select for output
display:
640×360
848×480
1024×768
1280×1024
1920×1080
640×480
960×540
1280×720
1600×1200
1920×1200
Captured video content is output to your application at
15, 30 or 60 frames per second
(your application
chooses one of these frame rates) when captured over USB 3.0.
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 HD outputs resolutions in commonly supported aspects ratios, color-coded according to table of
resolutions above and described in the table below:
