8 Upconvert Mode
These parameters select the type of up-conversion the Video Processor performs
on the selected input.
NOTE: Any Custom Size/Pos values will be applied on top of these Upconvert settings.
NOTE: When converting from 2K, the selections do not precisely describe the resulting
picture. For example, 4x3 pillar is not precisely 4x3, and 14x9 is not precisely 14x9.
However, picture scaling is such that the visual effect closely resembles an SD-to-
HD up-convert.
.
4x3 Pillar (default)
14x9 Pillar
Full Screen
LB to Full
Wide Zoom
Results in 4x3 image at center screen with black sidebars.
Results in 14x9 image, zoomed slightly to fill a 14x9 image with
sidebars.
Anamorphic full screen display.
Image is zoomed to fit the full screen (letterbox).
Using a combination of zoom and stretch, the image is sized to fit a
16x9 screen (this can introduce a small aspect ratio change).
AFD and Up-Conversion
Active Format Description (AFD) codes are carried in the vertical ancillary
(VANC) portion of HD SDI video signals, specified in SMPTE 2016 as follows: “AFD
information is intended to guide DTV receivers and/or intermediate professional
video equipment regarding the display of video of one aspect ratio on a display
of another aspect ratio.”
FS3 AFD processing (passing, removing, and re-inserting) occurs based on the
setting of parameter
.
Auto AFD mode fully defines the size, position, and aspect ratio of the output
raster. Thus, when in Auto AFD mode, any Custom Size/Pos settings are ignored,
and those menus are hidden. Likewise, when in Auto AFD mode, any Region Of
Interest settings are ignored, and those menus are hidden.
9 Sidebar Edge
This parameter adjusts the sidebar position where the center video meets the
pillarbox background video on both sides. The underlying hardware feature is
the same as Custom Right Crop and Custom Left Crop. This is effectively an extra
handle on the Left Crop and Right Crop parameters.
The Crop and Sidebar Edge controls are additive; increasing Sidebar Edge
(making the sidebars larger and the center-video smaller), equates to setting Left
and Right Crop values to smaller percentages. The Sidebar Edge can be set to 0
t128. A value of 0 produces a 4:3 center. Positive values produce wider
sidebars (and a narrower center).
0
(default)
0 to +128 (Variable)
Defaults to 0. Select a width value from 0 t128 to expand
or shrink the sidebars, which are filled with Background video (
4
Background Fill)
. Selecting a larger value causes the center picture
to become narrower while the sidebars expand.
About Frame Rate Output
UltraHD and 4K video can have high frame rates (50, 59.94) or low frame rates
(23.98 - 29.97). These two settings control whether these types of video will be
output as Level A or Level B, or as Quad or Dual link.
