FIT
FILL
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). The aspect ratio can be changed per input.
In Fill mode, if an aspect ratio adjustment is desired, the correct horizontal and vertical size
can be set up using Picture Controls.
In Follow mode, the input source material is displayed with its native aspect ratio, and either
letter box or pillar bars can be applied based on the horizontal and vertical size settings
under Picture Controls.
When FIT is selected, the image is zoomed in with top and bottom or left and right
information cropped out in order to fit the screen without letterboxing or adding pillars.
NOTE: The selected input aspect ratio setting is applied to both the archive and
confidence outputs. If the confidence resolution is different, the applied aspect ratio
can not be maintained. For example, if the archive resolution is 1080p with an aspect
ratio of 16:9, and the confidence display is 1024x768 with an aspect ratio of 4:3, the
input aspect ratio selection can not be maintained for both.
Description
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.
The input format is zoomed to fill the output
while the input aspect ratio is retained. Some
loss of image occurs represented by the
dimmed image outside the red block.
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.
