KONA LH Capture, Display, Convert v14.3 47 www.aja.com
This screen shows the KONA software files that have been installed on your
system. This information may be needed if you talk to an AJA Customer Service
representative to determine if files are missing or need updating.
Who is Controlling KONA?
There are times when you might have several applications open at one time, and
each of these might want to output their video through the KONA video output.
KONA is very flexible and most applications perform the necessary housekeeping
so they work correctly when they’re active and when they’re not. This means
that the application that is “active” (in front) will be granted control of the KONA
video output. Generally, when you switch to a different application, the previous
application lets go of the video output and the new application gets control.
Figure 31. AJA Control Panel Control Message
The AJA Control Panel in-use message will tell you the “active” application
that has control of KONA (see in-use message above) and what the format
selections are. If you click on another supported application that is running
(such as Adobe Premiere Pro or AJA TV), the AJA Control Panel in-use message
will report the change by displaying the new “In use” application. If no in-use
message is displayed, the AJA Control Panel is in control of KONA. If no QuickTime
applications are running, the board’s state is determined by the AJA Control Panel
application’s settings.
QuickTime Application Format Selection
If a running QuickTime application uses KONA for capture or output, it controls
the Primary format via its own menus and settings. For example, when the Third-
party editing application is active (it’s the front-most application) and has KONA
as its “A/V Device”, the KONA’s Primary format is determined by the application’s
“Video Playback” settings. These format selections are reported in the AJA
Control Panel block diagram.
QuickTime applications can start and stop and change modes—even while they
are running. And the behavior of different QuickTime applications can vary: some
applications take control of the interface as soon as they are launched and don’t
give it up until they quit, while other applications take control of the interface
only when they are the “front-most” running application and then relinquish
control when they’re not. Even these QuickTime applications may not relinquish
control until capture or output operations are completed.
Control Recommendations
We recommend you have the Control Panel running and visible at all times. When
the Control Panel is running in the background (not front-most) you can see what
the interface is doing and who has control of it.
