Glossary of terms

created). Used for high-quality distribution

and for archiving.

mV Abbreviation for millivolt (one-

thousandth of a volt). Unit of measurement

sometimes used to define the amplitude of a

video signal. See also IRE unit.

MXF Material eXchange Format. A file

exchange format standardized by SMPTE that

assures interoperability among devices and

systems. Panasonic P2 (Professional Plug-in)

as well as Sony XDCAM and XDCAM HD

use .mxf files rather than .mov, .avi, or .mpg

files, for example. MXF is designed for

today’s file-based workflows and provides a

common way of packaging video and audio

along with metadata so that information about

the content is maintained as it flows through

the production process.

N

nonlinear editing Random access editing

that generally uses video and audio clips

stored on disks. Nonlinear editing programs

let you rearrange and edit clips without

having to redo the entire production, and

provide instant cueing to any frame in a clip

without waiting for tapes to rewind.

NTSC National Television Systems

Committee. The NTSC RS-170A standard

defines a method of broadcasting a color

signal that can be received by both

monochrome and color TVs. It uses a

composite interlaced display comprised of

525 scan lines per frame, refreshed at a rate of

approximately 30 frames per second.

Broadcast systems in North America and

Japan use the NTSC standard.

O

old movie effect A Matrox effect that lets

you simulate the look of old film by adding

noise, dust, streaks, jitter, and flickers to your

clip.

organic wipe A wipe effect that uses a

grayscale gradient pattern to switch from one

image to another by gradually revealing the

second image according to the pattern

P

page curl A Matrox effect that lets you

peel or roll an image off the screen to reveal

another image.

PAL Phase Alternate Line. A video

standard that uses a composite interlaced

display comprised of 625 scan lines per

frame, refreshed at a rate of 25 frames per

second. This is the broadcast video standard

for most of Europe.

pan & scan effect A Matrox effect that

lets you convert clips from one aspect ratio to

another, such as from 16:9 to 4:3.

PCI slot Connection slot to a type of

expansion bus found in many computers. It is

smaller in size than older ISA slots and

provides connections to the PCI host bus at

speeds up to 66 MHz.

PCIe slot See PCI Express slot.

PCI Express slot A type of PCI slot that

uses a different and much faster

communications protocol than a 32-bit PCI

slot. PCI Express can accommodate the

higher speeds required for high-performance

peripherals such as display cards and network

controllers. PCI Express slots are available in

different sizes (x1, x4, x8, and x16). The

Matrox RT.X2 card is installed in a PCI

Express slot. Also called PCIe slot.

PCI-X slot A type of PCI slot that

increases the speed at which data can move

within the computer from 66 MHz to up to

133 MHz.

P-frame (Predicted frame) A frame

created during the MPEG or MPEG-2 IBP

compression process. A P-frame is created by

using motion vectors to predict the
