Framebuffer—the framebuffer is the "engine" in the KONA LHi where active video
operations take place using Final Cut Pro, other 3rd-party applications, or even the
KONA itself. The framebuffer has a format (called the "Primary Format" and color
space that it follows, as defined in the Tabbed Windows or via external application
software such as the "Easy Setups" in Final Cut).
It is important to realize that inside the Macintosh many applications can use the
KONA LHi (as you switch from window to window) and it may not always be obvious
which is currently controlling it. The AJA Control Panel displays the name of the
application controlling the card in red text on the Format and Control tabs of the
interface. If an application does not properly "let go" of the KONA as another takes
over-you'll be able to tell by looking at the Control Panel.
Primary (Framebuffer) Format—the video format currently assigned to KONA LHi. This
is the format that the framebuffer will use and is shown in the Control Panel using
the color blue. All icons in blue are the same as the Primary Format used by the
framebuffer. Also any text descriptions in the block diagram that appear in blue also
indicate that something is in the primary format. So, for example, if you see that the
input and output icons are blue, then you know that the same format is used
throughout the video path and that no format conversion is being performed. If a
different color is displayed on the input or output, green for example, then you know
that the KONA LHi is performing a format conversion in the video path.
Secondary Format—any format other than the currently selected Primary Format, is a
secondary format. As described previously, this means that either the Inputs or
Outputs are somehow different from the framebuffer's assigned format (i.e., the
"Primary Format"). This can be seen at a glance because the color will be different
than blue.
