Aspect Ratio
The Aspect Ratio adjustment allows the user to select between input rates to fill the
entire window for that channel (FILL), scale up to fit the channel window and keep the
original aspect ratio (FIT), or to allow each input rate to display in its native aspect ratio with
respect to the channel window (FOLLOW).
Aspect Ratio Screen Appearance Description
FOLLOW
The input format passes unchanged. A 4x3
format (represented by the red block on the
left) remains at its original aspect ratio. The
vertical dimension fills, but not the horizontal
dimension of the output or recording. Letter
box or pillar bars can be applied based on
the horizontal and vertical size settings.
FIT
The input format is zoomed to fill the
output with top and bottom or left and right
information cropped out in order to fit the
screen without letter boxing or adding pillars.
Some loss of image occurs represented by
the dimmed image outside the red block.
FILL
The input format is non-uniformly scaled
to fill the 16x9 output. A 4x3 input fills the
horizontal and vertical screen of the output
or recording with some distortion of the input
(default).
NOTE: The selected input aspect ratio setting is applied to both the recording and streaming
outputs. If the streaming resolution is different, the applied aspect ratio cannot be maintained.
For example, if the recording resolution is 1080p with an aspect ratio of 16:9, and the streaming
display is 1024x768 with an aspect ratio of 4:3, the input aspect ratio selection cannot be
maintained for both.
