3. TERMS AND DEFINITIONS
BACKGROUND: a “Background” is a source, typically originang from a computer. QuickVu enables you to
work with sll (frame) background — visually in back of all other sources.
LAYER: a “layer” is an image display element (such as a PIP window, Key, logo or Background) that has a visual
priority — either in front (or in back) of another layer. 1 frame non-resizable, up to 2 live layers resizable
available on the QuickVu.
PIP: a “PIP” (Picture In Picture) is a picture, typically of reduced size, which is posioned over another
background image or other PIPs. PIPs can be reposioned, reduced, enlarged and displayed. PIPs can overlap,
depending on their visual priority. QuickVu oers various slides, wipes, and fades for dynamic PIP entrances
and exits. A “ying” PIP is also possible using vercal, horizontal, or diagonal movement. A PIP is considered
as a layer.
FRAME: a “frame” is a full screen image which is selected from one of the sll frames you can capture. A
frame can be captured in ash memory from any video or computer source plugged into the machine.
KEYING: “Key” is an electronic process whereby a video image is electronically superimposed over another
source or background, by dynamically removing a poron of the rst image. For example, removing all content
of a certain color (such as green or blue) is called a Chroma Key, and removing content based on its brightness
or luminance levels is called a (Luma Key). Keys are typically used for tles, logos and special eects. QuickVu
allows you to key a live source (such as a camera shot with green or blue background, or a tle with a black
background) over any other source or sources.
SEAMLESS: Clean transion with no glitch or loss of sync while switching between two sources. For example,
fading through black to another source is a seamless transion.
TRUE SEAMLESS: Clean seamless transions with no glitch or freeze between two sources. For example,
crossfading from source to source is a true seamless transion.
RCS²: Remote Control Soware used to control, set up, and operate the device.
QUICK FRAME: The “Quick Frame” feature allows the instant display of a stored frame above all layers.
