DVD, VCD, and SVCD
There are several factors to consider in choosing an output format
for your project. These include your desired output quality, target
playback device, and viewing screen size, among others. Here are the
advantages and disadvantages that picking each output format
entails:
• Video Compact Disc (VCD) is a special version
of a CD-ROM that uses the MPEG-1 format.
The quality of the exported movie is almost
the same, but usually better than VHS tape-
based movies. A VCD can be played back on a
CD-ROM drive, VCD player, and even on a
DVD player.
• Super Video CD (SVCD) is commonly
described as an enhanced version of VCD. It is
based on MPEG-2 technology with Variable
Bit Rate (VBR) support. The typical running
time of an SVCD is about 30-45 minutes.
Although you could extend this to 70
minutes, you will have to compromise sound
and image quality. SVCDs can be played back
on stand-alone VCD/SVCD players, most
DVD players, and all CD-ROM/DVD-ROM
with a DVD/SVCD player software.
• Digital Versatile Disc (DVD) is popular in
video production because of its quality. Not
only does it guarantee superb audio and video
quality, it can also hold several times more data
than VCDs and SVCDs. DVDs make use of
the MPEG-2 format, which has a much
bigger file size than MPEG-1, and can likewise
be produced as single or dual-sided, and single
and dual-layered. They can be played on
stand-alone DVD players or on the DVD-
ROM drive of your PC.
