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.
NLE
Non Linear Editing. Conventional editing on a VCR is necessarily linear because you
must access clips on a video tape in order. Computer editing can be done in any
order that is convenient.
Noise
Small audible or visual discrepancies that adversely affect audio and video files
which have been recorded or captured incorrectly or with faulty equipment.
NTSC/PAL
NTSC is the video standard in North America, Japan, Taiwan, and some other
regions. Its frame rate is 29.97 fps. PAL is common in Europe, Australia, New
Zealand, China, Thailand, and some other Asian places, which has a frame rate of
25 fps. There are other differences. In the world of DV and DVD, NTSC has the
video resolution of 720x480 pixels, while PAL has 720x576 pixels.
Overlay
These are the superimposed video or image clips over existing clips in your project.
Plug-ins
Plug-ins are utilities that add more functions and effects to a program. In Ulead
VideoStudio, plug-ins have made it possible for the program to automatically
recognize capture devices as well as output videos for different purposes such as
for e-mail, Web page, video greeting cards, and DV recording.
Profile
A Profile covers various attributes for a Windows Media Format file such as bit rate,
number and type of streams, compression quality, frame size and so on.
Project File
In VideoStudio, a project file (*.VSP) contains the required information to link all
associated image, audio, and video files. You need to open a project file first before
starting video-editing in VideoStudio.
