AJA Control Panel, Test Pattern Choices

Hold Last Application: this selection directs Io HD to hold and output the last frame

of video from the last application to control Io HD. This can be helpful when

operating in an environment where you're switching back and forth between

multiple application windows.

Tip:

pressing and holding the Apple COMMAND key while clicking in the AJA

Control Panel—while in any software application (Final Cut, etc.)—causes control

of the Io HD to stay with that application, rather than shifting to the Control Panel.

This works regardless of the setting of “Default Io HD Output.”

Genlock (Freerun, Ref In, Video In)—selects how Io HD will synchronize program

video:

Freerun: In this mode, Io HD generates sync without an external reference

source

Ref In: Directs Io HD to use the Ref Video source for sync (usually an analog

black burst video signal)

Video In: Directs Io HD to use whichever video input source has been selected

in the Inputs tab window for sync.

Timing (Horiz and Vert)—these two pull-downs allow output timing adjustment

with reference to the Ref Video source selected. The Horizontal reference can

be adjusted by selecting a number of pixels (clocks) to offset. Vertical can be

adjusted by specifying a number of lines to offset.

Stand Alone Mode—while connected to the Mac, Io HD can be configured for a

set of parameters and then disconnected from the Mac for use by itself as a

stand-alone converter. An example would be using the Io HD in Stand Alone

Mode as an SD to HD upconverter.

To use the Io HD in this way, select the Io HD Stand Alone Mode pulldown

from the Control tab screen. Next, select Current Setting or Factory Setting.

Factory Setting is the factory default settings as shipped from AJA. Selecting

Current Settings means using the exact settings currently configured on the AJA

control panel when in standalone mode. After choosing one of these selections,

click the Burn... button to save the settings into Io HD’s non-volatile memory

for use unconnected from a Mac.
