Default KONA Output Choices and their meanings:
Input Pass through: this selection directs KONA 3 to route video from its selected input
through the card for processing and output. When this selection is in effect, all
Primary/Secondary Format selections are available for selection in controlling the
output. This in effect makes the KONA 3 a converter when used in conjunction with the
AJA Control Panel application.
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 KONA 3,
configured for up-conversion in the Control Panel and then passed through to the HD
VTR for recording.
Test Pattern: this selection directs KONA 3 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 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 3 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 3 to hold and output the last frame of video
from the last application to control KONA 3. This can be helpful when operating in an
environment where you're switching back and forth between multiple application windows.
