inpoints, outpoints, reel numbers, mode (V, A1, A2), transitions (Cut, Dissolve,
Wipe), and peripheral device effects data. There can be multiple EDL files on disk.
Effects Pathway
A switcher feature in which video from a keyer is routed to external devices (for
example, a DME), and then returned to the switcher for additional processing.
Sony's term for the Effects Pathway is Processed Key.
Ethernet
A computerized network (and system of protocols and commands) for transferring
data between electronic devices.
Fader Arm
The lever on a switcher that manually controls the progress of an effect. The
position of the level typically controls the amount of the A-Bus signal and the B-
Bus signal that contributes to the mix, wipe, or key. On the DVS-2000C, the Fader
Arm also controls the DME timeline.
GPI (General Purpose Interface)
A communications port that controls "triggering" with frame-accuracy. Typically
used with devices that do not have serial control capability. On an editing system,
the GPI port typically sends trigger pulses to peripheral devices. On devices such as
switchers and digital effects, the GPI port typically receives triggers from the editor.
GUI
Graphical User Interface. A term that describes a status display based on graphics
and icons, rather than strictly on numbers and letters.
Initialization Menu
A secondary BVE-9100 menu used to set up EDL specifications and overall system
"preferences" such as preroll and color framing.
Interface
A set of software instructions that allows the editing system to control a peripheral
device such as a VTR, ATR, DVE or switcher. The better the interface, the greater
the ease with which the operator can assemble a program.
Key Clip, Gain, Density
Also called "Clip," in switcher terminology, the process of fine-tuning a key — of
any type (luminance, linear, or chroma). Clipping sets the threshold for the hole-
cutting circuitry, while "gain" defines the range and sensitivity of adjustment. The
"density" is the transparency or opacity of the key, as revealed over a background.
A hole will be cut in the Background video in any location where the Foreground
luminance level is greater than the clip level. "Fill" video replaces the holes.
