User Manual

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 LHi, configured for

upconversion in the Control Panel and then passed through to the HD VTR for recording.

Test Pattern: this selection directs KONA LHi 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 LHi 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

Hold Last Application: this selection directs KONA LHi to hold and output the last fram e of

video from the last application to control KONA LHi. This can be helpful when operating

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

windows.

Genlock (Freerun, Ref In, Video In)—selects how KONA LHi will synchronize program video:

Freerun: In this mode, KONA LHi generates sync without an external reference source

Ref In: Directs KONA LHi to use the Ref Video source for sync (usually an analog black

burst video signal)

Video In: Directs KONA LHi 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.
