KONA LHi Installation and Operation Manual — Using The KONA LHi Control
QuickTime Application—1st Priority
If a running QuickTime application uses KONA LHi for capture or output, it controls the Primary
format via its own menus and settings. For example, when Final Cut Pro is active (it’s the
topmost application) and has KONA LHi as its “A/V Device”, then the KONA LHi'S Primary format
is determined by Final Cut's “Video Playback” submenu (under the “View” menu) or its “Audio/
Video Settings...” dialog under A/V Devices.
When a QuickTime application is in control of the KONA LHi board—versus one of the other
masters—it will be indicated by a label in both the KONA Control Panel's
Formats and Control
tabs. The KONA LHi Control Panel’s Primary Format menu will also indicate that it is not active
while the QuickTime application is running—it will be grayed-out.
What can be confusing is that 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 board as soon as they are launched and don't give it up
until they quit, while other applications take control of the board only when they are the “front-
most” running application and then relinquish control when they’re not. Final Cut Pro is one of
the latter type QuickTime applications. This difference in behavior can surprise you when you
click in and out of multiple QuickTime application windows.
To illustrate such possible confusion, consider this multiple application scenario:
1. Open Final Cut Pro, select KONA LHi as the A/V device. FCP takes control of the board and
tells it what Primary format to use. If one of the FCP windows covers up the KONA Control
Panel application (which typically happens), you won't be able to see the
“Kona card is in
use by Final Cut Pro” message displayed in the Control Panel, or be able to tell which
format FCP has selected. (This is why we recommend you arrange your display so you can
see the Control Panel at all times.)
2. Next, you want to see what the KONA card is doing, so you find the KONA Control Panel
application by clicking around on the desktop, eventually clicking on the Control Panel to
make it visible. As soon as FCP realizes it is now running in the background, it gives up
control of the KONA LHi board. The KONA Control Panel application takes away the
“
...Final Cut Pro” message.
3. With the Control Panel the topmost application—and in control of the board—you now
switch to a different Primary format.
4. However, when you click back on Final Cut Pro and bring it back to continue your project,
it becomes the master again and resets the board's Primary format to the one
determined by Final Cut’s A/V Settings dialog. To further the surprise, if FCP's windows
are covering the KONA Control Panel window, the change will be hidden and you won’t
know why the board isn't doing what you told it earlier via the Control Panel.
The moral of the story: keep the Control Panel visible so you can learn what various QuickTime
applications are doing when they control KONA LHi—and then you can step in and change the
application’s settings and Control Panel settings as desired to get the configuration you expect.
Mac Desktop Video—2nd Priority
If you choose “Macintosh Desktop” as your KONA Default Video Output (Control Tab), then the
Mac Finder uses the KONA LHi board as a second (or third, or fourth...) graphics “desktop”
output—
as long as there isn't a QuickTime application running. When the Finder is in control, the
Primary Format is dictated by the System Preferences “Displays” panel or by you selecting “Show
Displays in the menu bar”, from the Displays menu near the right side of the main menu bar).
