KONA LH Capture, Display, Convert v14.3 26 www.aja.com
Test Pattern
This selection directs the KONA card to output a choice of preset pattern when no
other application is using the KONA card. 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 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 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 until the AJA Control Panel application closed.
Hold Last App
This selection directs KONA to hold and output the last frame of video from
the last application to control KONA. This can be helpful when operating in
an environment where you’re switching back and forth between multiple
application windows.
Playback Timing
Use these controls to set Genlock and Timing adjustment.
Genlock
Selects how KONA will synchronize program video:
• Freerun: In this mode, KONA generates sync without an external reference
source
• Ref In: Directs KONA to use the Ref Video source for sync (usually an analog
black burst video signal)
• Video In: Directs KONA 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:
• Horizontal selects a number of pixels (clocks) to offset
• Vertical specifies a number of lines to offset
