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
up-conversion in the Control Panel and then passed through to the HD VTR for recording.
Test 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 Screen 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.
