86 VIDEOSTUDIO USER GUIDE
Glossary
Analog
A signal that is not digital. Most VCRs, radio/
television broadcasting, AV in/out, S-VIDEO, and
stereos are analog. Computers are digital, dealing in
ones and zeros. Information from an analog source
must be digitized to be used on a computer.
Capture
The recording of video or images to a computer
hard disk.
Clip
A short section or part of a movie. A clip can be
audio, video, still images or a title.
Codec
COmpress and DECompress. All video on a
computer uses a special algorithm or program to
process video. This program is called a codec.
Color Clip
A simple background color used in a movie. It is
often used for titles and credits since they stand
out clearly against the solid color.
Compression
Making a file smaller by removing redundant data.
Nearly all digital video is compressed in some way
or another. Compression is achieved through a
codec.
Data Rate
The amount of data per second that is transferred
from one part of your computer to another. In digital
video, the data rate of your source is very
important: CD-ROMs have lower data rates than
hard disks. The data rate of the Internet is very low.
Digital
Computer data consisting of ones and zeros.
Contrast digital information with analog.
Driver
A software program that controls the connection
between a specific device and a computer.
Effect
In VideoStudio, an effect is a special computer
generated transition between two video clips.
Frame
A single image in a movie.
Frame Rate
The number of frames per second in a video. NTSC
video is commonly 29.97 frames per second (fps),
but smaller video files can be created on the
computer by using lower frame rates, like 15 fps
(not suitable for VCD or DVD).
Library (Ulead VideoStudio)
The Library is the repository for all of your media
clips. You can store video, audio, titles, or color
clips in the Library and instantly retrieve them for
use in a project.
Mark In/Out
Points in a clip that have been marked for editing
and trimming purposes. A section can be selected
from a longer clip by setting its beginning (Mark in)
and ending (Mark out).
MP3
Abbreviation of MPEG Audio Layer-3. MP3 is an
audio compression technology that produces near
CD audio quality at a very small file size, making it
transfer quickly over the Internet.
MPEG-1
A standard for video and audio compression used
in many products like VCD. For NTSC, its video
resolution is 352x240 pixels at 29.97 fps. For PAL,
it works at 352x288 pixels at 25 fps.
MPEG-2
A subset of MPEG-1. It’s a standard for video and
audio compression used in products like DVD. For
NTSC DVD, its video resolution is 720x480 pixels at
29.97 fps. For PAL DVD, it works at 720x576 pixels
at 25 fps.
