Io X3 Capture, Display, Convert v16.2 15 www.aja.com
• If the input and output icons are blue, you know that the same format is used
throughout the video path. No format conversion is being performed.
• If the input or output icon colors differ (blue input and green output icons for
example), you know that a format conversion is being performed.
Controlling Application
It is important to understand that the computer can contain many applications
that can use the AJA device (as you switch from window to window) and it may
not always be obvious which currently controls it.
Figure 5. Control Panel In Use Message (in red)
In the top right corner, the Control Panel displays the name of the application
controlling the unit. In some cases, applications may not always properly “let go”
of the I/O interface as another takes over—you’ll be able to tell by looking at the
Control Panel.
Controlling Application Format Selection
If a running controlling application uses Io X3 for capture or output, it controls the
Device 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 Io X3 as its
“A/V Device”, the Io X3’s Device Format is determined by the application’s “Video
Playback” settings. These format selections are reported in the AJA Control Panel
block diagram.
Controlling applications can start and stop and change modes—even while they
are running. And the behavior of different controlling 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 controlling applications may not relinquish
control until capture or output operations are completed.
AJA Control Panel Restart Services
AJA Control Panel Restart Services is new functionality (since v6.1) that allows for
restarting the AJA services if necessary. This can help if various applications begin
contesting for access to the Video I/O device. In this situation an AJA Agent is
not running message can appear as the controlling application status. Hovering
your cursor over that message displays a Restart Agent button, which clicking on
will bring Control Panel back to its startup state. Then an application can freshly
acquire control of the I/O device.

NOTE: On Windows computers you must run Control anel as Administrator in order to
use the restart services feature.
