Video Editors are programs that enable you to modify digitized
videos. With a video editor, you can cut segments, re-sequence frames, add
transitions, compress a file, and determine a video’s frame rate (the number of
still images displayed per second). Video editors also enable you to save video
files to some or all of the following video file formats:
Moving
Picture Experts Group (MPEG): A family of video file formats
and lossy compression standards for full-motion video.
QuickTime: A video
file format developed by Apple Computer. It is widely used in multimedia
Video for
Windows: The native (or original format a program uses internally)
video file format for Microsoft Windows. Often called AVI because these files
use the .avi file extension, this format is inadequate for full-screen,
broadcast-quality video.
Because a huge amount of data must be stored to create
realistic-looking video on a computer, all video file formats use codec
techniques. For the best playback, special video adapters are required. These
adapters have hardware that decodes videos at high speed. To make video
available on the Internet, streaming video formats have been developed. These
formats enable the video picture to start playing almost immediately after the
user clicks the video.
