Annex: Digital Video and Data Storage 369

Hard disk capacity: A VCD can store about 70 minutes of video. A typical
motion picture must therefore be stored on two VCDs. In order to get as much
video data on a normal CD as possible, one must forego correction information
on VCD/SVCD formats within the individual sectors (sub-ranges) of a CD. You
can therefore fit 720 MB of video data on a 650 MB blank CD. Due to
improved burning and scanning technology it is now possible to burn up to
985 MB video data on a 99min blank CD.
Encoder settings: Normally the video CD data is played at a data rate of 1150
kBits video and 224 kBits audio. By increasing the video bit rate to 3000kBits
you can get the same resolution and an better-quality audio bit rate. Movement
artifacts disappear almost completely at approx. 2000 kBits with the picture
appearing a little less sharp. This pre-supposes, however, that the player can
also play back such a bit rate. The fact that many DVD players can handle an
increased data rate is due to well written player software.
Experiment with higher data rates: If you do not need the full running time of
the VCD, then you can experiment with space to improve the quality of the
video!
JPEG disc
The "JPEG disc" is a special case for slideshows. No video file is created to be
burned, but rather every photo in the disc project is exported individually with
effects and burned to CD or DVD. Many modern DVD players can play JPEG
files directly.
If a project contains several slideshows, a subfolder will be created for each
one, and the corresponding images will be placed into each one. This means
that there are no menus, no sound, no animated effects or transitions –
although it does offer the best possible quality available for playback on TV.

Slideshow disc
All slideshow image and audio files will be burned onto CD or DVD, together
with any effect settings and the MAGIX Media Manager CDR player program. A
MAGIX Media Manager CD is designed especially for photo projects
(slideshows).
The original photos are burned onto CD; Ideal for backing up valuable
recordings. During playback on your PC, the highest possible picture quality is
made possible. The following photo effects can be played by Media Manager.
 Brightness, contrast, gamma
