Io HD Installation and Operation Manual — Using The AJA Control Panel
AJA Control Panel, Block Diagram
Framebuffer—the framebuffer is the “engine” in the Io HD where active video
operations take place using Final Cut Pro, other 3rd-party applications, or
even Io HD 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 Io HD (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 Io HD in red text on
the Format and Control tabs of the interface. If an application does not
properly “let go” of the Io HD as another takes over-you'll be able to tell by
looking at the Control Panel.
Primary Format—the video format currently assigned to Io HD. 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 Io HD 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.
