7.2 Sidebar Edge
This parameter selects the width of the Sidebar Keyer when turned on via parameter
7.1. Sidebars with the video selected in 7.1 will appear, on the right and left of the
active video input (selected in 2.1). Sidebar Edge can be set to -128 through +128.
A value of “0” produces a 4:3 center. Positive values produce wider sidebars (and a
narrower center).
Conflicts between Output Format (1.1), Sidebar input format, main input (2.1)
and its associated format can cause an Alarm condition. Likewise, selecting analog
inputs for both the main input and the sidebar input will cause an Alarm condition.
Turning Sidebar Key on while in 'Follow Input' mode will also cause an Alarm,
since the sidebar keyer requires that the main input be upconverted.
When a Sidebar-related Alarm condition appears, Sidebar Key status menus will be
displayed to help you find the cause of the conflict.
10.1 Proc Amp
This parameter turns the Proc Amp on and off.
Note: Proc Amp controls (Parameters 10.1 through 10.5) are independently kept
for each separate input: SDI 1, SDI 2, Composite, S-Video, and Component.
