Using DVD...

DVD stands for Digital Versatile Disc and can be burned in many different formats and used to store any kind of data. DVD-Video discs contain video encoded in the MPEG2 format. DVD discs can have a single layer of information burned on one side (single-layer), two layers of information on one side (dual-layer) or have information on both sides (double-sided). Each layer or side can contain up to 4.7 Gigabytes of video or other data.

DVD-Video discs are designed to play back in hardware DVD players or using DVD playback software on computers with DVD drives installed. The MPEG2 video on a DVD must be encoded within the DVD specification (for example it must be encoded with a bit rate of between 1 and 10 megabits per second and must have video designed for playback on either NTSC or PAL television systems). The video is compiled along with graphics and sound for interactive menus into the DVD-Video format during the DVD authoring process.

The advantages of distributing your video on DVD over VCD are:

  • quality – DVD uses a more sophisticated and better compression standard and can also hold a lot more data than VCD

  • interactivity – the ability to create complex menu structures, subtitles and simultaneous video streams for additional camera-angles etc.

  • familiarity – audiences in some parts of the world are much more at ease with DVD technology.
