VCD
stands for 'Video Compact Disc' and basically it is a CD that contains
moving pictures and sound. If you're familiar with regular audio/music
CDs, then you will know what a VCD looks like. A VCD has the capacity to
hold up to 74/80 minutes (on 650MB/700MB CDs respectively) of full-motion
video along with quality stereo sound. VCDs use a compression standard
called MPEG to store the video and audio. A VCD can be played on almost
all stand alone DVD Players and of course on all computers with a DVD-ROM
or CD-ROM drive with the help of a software based decoder / player. The
quality of a VCD is about the same, but usually better than VHS tape based
Movies.
