3. TERMS AND DEFINITIONS
BACKGROUND:
a “Background” is a source, typically originating from a computer. QuickVu enables you to
work with still (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 positioned over another
background image or other PIPs. PIPs can be repositioned, reduced, enlarged and displayed. PIPs can overlap,
depending on their visual priority. QuickVu offers various slides, wipes, and fades for dynamic PIP entrances
and exits. A “flying” PIP is also possible using vertical, 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 still frames you can capture. A
frame can be captured in flash 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 portion of the first 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 titles, logos and special effects. QuickVu
allows you to key a live source (such as a camera shot with green or blue background, or a title with a black
background) over any other source or sources.
SEAMLESS:
Clean transition with no glitch or loss of sync while switching between two sources. For example,
fading through black to another source is a seamless transition.
TRUE SEAMLESS:
Clean seamless transitions with no glitch or freeze between two sources. For example,
crossfading from source to source is a true seamless transition.
RCS²:
Remote Control Software 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.
