MPEG-4
A video and audio compression format that is commonly used in mobile
devices and video streaming in the Internet that provides high-quality
videos at lower data rates.
NLE
Non-Linear Editing. In the past, conventional editing on a VCR was
necessarily linear because of the need to access clips on a video tape in
order. Computer editing can be done in any order that is convenient.
Noise
Noise may be found in audio and video. In audio, it manifests as
unwanted residual hiss while they are random image specks and dots
onscreen in video. These are electronic interferences that are most
common in analog audio and video.
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 720 × 480 pixels, while
PAL has 720 × 576 pixels.
Overlay
These are 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
Corel VideoStudio Pro, 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.
