KONA 3G Installation and Operation Guide — Control Panel Operation
signal might be routed from the SD VTR to the KONA card, configured for upconversion
in the KONA Control Panel and then passed through to the HD VTR for recording.
Test Pattern: this selection directs KONA 3G to output a choice of preset pattern when no
other application is using the KONA 3G. You can choose from:
Black, Color bars (75% or 100%), Ramp, Multiburst, Line Sweep, Multi Pattern, or Flat Field.
In addition to the preset 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.
While in Test Pattern mode, you can select RGB or YUV output via a pulldown menu.
Note: the graphic file will not be scaled to fit. If it's smaller than the current frame buffer format,
KONA 3G 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.
Hold Last Application: this selection directs KONA 3G to hold and output the last frame of
video from the last application to control KONA 3G. 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—causes control of the KONA 3G to stay with that
application, rather than shifting to the Control Panel. This works regardless of the setting of
"Default Output. "
Playback Timing—Use these controls to set Genlock and Timing adjustment.
Genlock (Freerun, Ref In, Video In)—selects how KONA 3G will synchronize program video:
Freerun: In this mode, KONA 3G generates sync without an external reference source
Ref In: Directs KONA 3G to use the Ref Video source for sync (usually an analog black burst
video signal)
Video In: Directs KONA 3G 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.
