Control Screen
Figure 26. Control Screen, KONA 4 in UFC Mode
The KONA card can be controlled by various software applications running on
a host computer. The Control screen is where you select how the KONA directs
video and is used by application software. This screen also provides control for
configuring output timing with regard to external reference video and horizontal/
vertical delay.
Default Output
This is where you select what the KONA card will output as a default when no
application has control of the board, such as when the Mac Finder or Windows
Navigation Pane is active. Since KONA can be controlled by software applications
as well as Control Panel, the output can change dynamically. When you select
many video applications, they will take control of the KONA inputs and outputs.
However, when an application that doesn’t take control is active, these settings
determine what KONA will output.
Input Passthrough
This selection directs KONA to route video from its selected input through the
card for processing and output, and enables Capture Mode.
NOTE: Selecting Input Passthrough on a KONA 4 card in UFC Mode essentially makes the
KONA card a converter. No applications other than the AJA Control Panel need be
open to convert audio and video from one format to another. For example, if you
need to dub an SD source tape that needs to be HD, the signal can be routed from
the SD VTR to the KONA card configured for up-conversion in the AJA Control
Panel and then passed through to the HD VTR for recording.
