Key Fill
The video which fills the hole cut by the keying circuitry. Typically, switchers
provide a variety of choices for the fill source — internal mattes, external video, or
"self" fill are several examples.
Key Mask
A key modification system that protects a portion of the foreground video from
being keyed. Most switchers allow you to mask keys with the internal pattern
system and associated modifiers.
Key Signal
The signal that electronically cuts the hole in the Background video signal. Key
signals can be switcher-generated or originate from external sources such as the
DME or character generators.
Keyframe
In a digital effects device, a point along a timeline where an action or change
occurs. In a DVE, such as the DME-7000, keyframes occur at specific points of
image manipulation. The BVE-9100 controls keyframe timelines for a variety of
devices including the DME-series digital effects units and DVS-series switchers.
Keying
The process of superimposing video from one source (the Foreground) on top of
another source (the Background). A variety of key "types" are available in most
switchers, including Self Key, Linear Key, Chroma Key, and Key Mask.
List management
A set of software tools for manipulating EDL timecode numbers. Tools include the
ability to move, copy, and renumber events (and blocks of events), clean overlaps
and sort the list.
M/E
Mix/Effects or Mix Effects Amplifier. The portion (or "bank") of a video switcher
where video signals are processed to select sources and create mixes, fades, wipes,
keys, and other special effects.
Master/Slave Mode
Also known as "Sync Jog." A method for locking two or more source devices
together in an edit event. Typically used in situations where the matte is on one
reel, and the fill is on another.
Peripheral device
Any device connected to the BVE-9100 via serial communications or GPI.
Category includes VTRs, ATRs, Video Switchers, Audio Mixers, Color Correctors,
DVEs, and DDRs.
