No applications other than the AJA Control Panel need to be open to convert

audio and video from one format to another. For example, if an SD source tape

needs to be dubbed to an HD tape, the signal might be routed from the SD VTR

to the LHe Plus, configured for upconversion in the Control Panel and then

passed through to the HD VTR for recording.

þTest Pattern: this selection directs KONA LHe Plus to output a choice of preset

pattern when no other application is using the card. In addition to the provided

test pattern choices, a “Load File...” selection at the bottom of the menu allows

you to load any standard Mac RGB graphics file (.tif, .psd, etc.) into the frame

buffer for display.

Note: The graphic file will not be scaled to fit. If it's smaller than the current frame buffer

format, KONA LHe Plus will center it in the frame. If it's larger than the current frame

buffer format, it will be cropped on the right and bottom. Also some graphics formats and

bit depths may not be supported. Once a graphic file is loaded into the frame buffer it will

be retained until it is overwritten by another graphic or test pattern, or when power is

turned off. Graphic file names are only “remembered” in the menu as long as the AJA

Control Panel application is running.

AJA Control Panel, Test Pattern Choices

Warning: Format: When Test Pattern is selected, the color Format menu is active

and allows you to select either 10-bit YUV or 10-bit RGB for the default output color format.

Hold Last Application: this selection directs LHe Plus to hold and output the last

frame of video from the last application to control LHe Plus. 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 KONA to

stay with that application, rather than shifting to the Control Panel. This works regardless

of the setting of “Default Output.”

Genlock (Freerun, Ref In, Video In)—selects how KONA LHe Plus will synchronize program

video:

Freerun: In this mode, KONA LHe Plus generates sync without an external

reference source

Ref In: Directs KONA LHe Plus to use the Ref Video source for sync (usually an

analog black burst video signal)

Video In: Directs KONA LHe Plus to use whichever video input source has been

selected in the Inputs tab window for sync.
