Color Meanings
All items in the AJA Control Panel block diagram are color-coded to show what is
happening in real time. This applies to both icons and text. These colors indicate:
Blue
Video is same format as the Device Format (framebuffer).
Green
Indicates that KONA is performing an active change to the video making it
different from the Device Format (e.g., down-conversion).
Red
The selected operation cannot be performed.
Yellow
Reference video (black burst or other reference source).
Input/Output Icons
The input and output icons are triangles that together with their color show all
the input and outputs and their status (selected, not selected, input present or
not, format, etc.). A complete video path is shown when inputs and outputs are
connected with lines going to/from the framebuffer.

Framebuffer
The framebuffer is the “engine” where your third-party applications interface with
the AJA device. The framebuffer has a format (called the “Device Format”) and
color space that it follows, as defined in the linked menu screens or via external
application software.
Device Format
The Device Format is the media format written to disk and used in your project.
This is the format that the framebuffer will use and is shown in the Control Panel
using the color blue. It is the format that the third-party application software will
either receive from the AJA hardware, or is sending to the hardware. All icons in
blue are the same as the Device Format used by the framebuffer. Also any text
descriptions in the block diagram that appear in blue indicate that something is
in the Device Format. For example:
• If the input and output icons are blue, you know that the same format is used
throughout the video path. No format conversion is being performed.
• If the input or output icon colors differ (blue input and green output icons for
example), you know that a format conversion is being performed.
Converted Format
NOTE: A Converted Format is not available on a KONA 4 operating in 4K Mode, or on the
KONA 5 or KONA 1 cards.
