Format Screen
Figure 14. AJA Control Panel, Format Screen
The Format Screen shows the video format currently in use by the KONA
framebuffer (called the Primary Format) and allows you to change it. All
throughout the Control Panel, choices are always presented based on what KONA
can do with the signals available and the inputs/outputs selected. For example,
on the Format screen, if the output or inputs are a different format than the
primary, then you’ll see an additional information pane that allows you to view
and edit the secondary format—including control over whether up/down/cross
conversion is employed.
IMPORTANT: Do not confuse this Format function screen conversion, which uses AJA
hardware and operates on either Mac or PC, with the separate Conversion
function screen, which uses QuickTime for conversion and is only available on
Mac.
Video Format (Primary and Secondary)
These pull-down menus show the currently selected formats. If you select an
alternate value in the Primary Format using the pull-down, it will change the
format used by KONA’s framebuffer.
When a change is made via the Video Format pull-down or by clicking an icon
and selecting a new format via a contextual menu, the block diagram will change
to reflect the new format. In the case of a Secondary Format, the formats available
can vary based on what the Primary Format is and the input signal (frame rates of
input sources limits the to/from conversion choices).
The “Secondary Video Format” pull-down menu lists all compatible formats
for selection (incompatible formats are not shown). This allows you to see what
you’ve chosen, and also see those formats that are compatible with the selected
Primary format.
Pixel Format
Use this pulldown menu to choose: YUV-10, YUV-8, RGB-10, or ARGB-8 or RGB-12.
