VCD, SVCD and DVD - Quality, Capacity and Media Types |
| |
|
| |
|

 |
VCD, SVCD and DVD are
popular media for video content distribution. Each medium
is unique and has its pros and cons. With Digital
Media Converter, you can convert your videos to
video file formats that can be directly burned onto
VCDs, SVCDs or DVDs. |

VCD:
VCD is a high-density, optical storage medium. It looks
just like a music CD, though it stores video data using
compressed MPEG-1 video. It has the capacity to hold
up to 74/80 minutes on a 650MB/700MB CD respectively,
of video with stereo quality sound. VCDs are stored
on CD-ROMs, making them one of the least expensive, storage
media and compatible with a wide array of devices. You
can play VCDs on most DVD players and PCs with Windows
Media Player. You can use any burning software such as
Nero to burn files in VCD format to
CD-R. |

It is also
possible to add simple menus, and photo album/slide
shows with background audio. These features make it
a good low-cost choice for video authoring. |

SVCD:
SVCD stands for Super Video CD. It bridges the quality
gap between the traditional VCD and the DVD. The
audio and video quality
of a SVCD is better than VCD because of the higher
resolution of SVCD and the fact that it stores MPEG-2 Video,
though it also depends on how much data you choose
to store. Generally, the less data per CD, the higher
the quality. Like VCD, data is stored on a CD-R. The
typical running time for an SVCD disc (with full resolution
and quality) is 35-45 minutes. It can be played on
most stand-alone DVD Players and on PCs with a DVD-ROM
or CD-ROM drive, with the help of Windows Media Player
and an MPEG-2 decoder. MPEG-2 decoders are not pre-installed
on Windows, you need to download and install an MPEG-2
decoder on your PC to view SVCD and MPEG-2 videos. |

DVD:
DVD stands for Digital Versatile Disc. A DVD-R can store
up to 8 hours of very high quality DVD-Video encoded
in MPEG-2 format. DVD files can be burned on DVD-ROMs
to play the video on stand-alone DVD players. If you
plan to play your DVD on a PC, then you need an MPEG-2
decoder. If such a decoder is not installed, Windows
Media player will display an error message that it was
unable to find a codec to play the file. DVDs have a
fixed pre-defined dimension. If you play them on your
PC, they may seem to be distorted or stretched. However,
the video should look fine on your DVD player. If you
intend to burn your videos to DVD-ROMs, the dimensions
should be compliant with the dimensions listed in the
table below. |
