The amount of energy delivered to the recording head and to the magnetic tape. Indicated by the VU meter and measured in nanowebers per meter.
Industry:Software
A term used to describe a picture condition in which objects appear to be extended horizontally beyond their normal boundaries in a blurred or “smeared” manner.
Industry:Software
A coding technique used in AC-3 audio compression.

a) To transfer information, usually from a processor to memory or from main storage to an output device. b) To record data in a register, location, or other storage device.
Industry:Software
a) An effect selected by the PST PTN push-button where a wipe pattern is used. The characteristics of the pattern are set using the pattern controls. If the effect is wiped on-air over an existing onair background, the wipe pattern will only move as far as the limit set by the vertical and horizontal limit controls. This is sometimes called a preset wipe or a wipe to a pattern limit. If the effect is mixed on-air, it is called a mix to a pattern limit. b) The ability to set both horizontal and vertical limits to the size a pattern will grow to when the fader is moved to the B bus.
Ampex switchers can wipe to a preset size, mix in a pattern already at a preset size, and mix or wipe in keys with preset limits. Mixing in a key using preset patterns allows portions of the key to be masked off, and this is the mask key feature on Ampex switchers.

a) A single, continuous narrow strip of the picture area containing highlights, shadows and half-tones, determined by the process of scanning. b) Horizontal or near-horizontal lines sampling a television image in the vertical direction. In tube-type cameras and displays equipped with CRTs, the scanning lines are caused by electron beam traces.

Industry:Software
Any process by which the surface smoothness of the tape coating is improved after it has been applied to the base film.
Industry:Software
A specialized oscilloscope which demodulates the video signal and presents a display of R-Y versus B-Y. The angle and magnitude of the displayed vectors are respectively related to hue (R-Y) and saturation (B-Y). The vectorscope allows for the accurate evaluation of the chrominance portion of the signal. Some vectorscopes can select either 75% or 100% color bars. Make sure the correct mode is selected or the chroma gain can be misadjusted.
Industry:Software
A feature of some tape recorders that makes it possible to stop the movement of tape temporarily without switching the machine from “play” or “record.”
Industry:Software
A feature on many video cameras and camcorders that allows the videographer to see the last few seconds of video recorded on the videotape.
