There
are four main stages to DVD/SVCD/VCD production:
Authoring - Creating an interactive framework
for a DVD/SVCD/VCD title
Content formatting - Converting source assets
to the formats required for DVD/SVCD/VCD (MPEG video
and PCM or Dolby Digital audio for DVD, MPEG-2 video
and MPEG-1 layer II or MPEG-2 audio for SVCD, and
MPEG-1 Video and MPEG-1 layer II audio for VCD)
DVD-Video multiplexing - Formatting all of
the source material and authoring information into
a DVD/SCVD/VCD-readable file and directory structure
DVD Disc writing - Writing the final DVD/SCVD/VCD
files to a DVD-R, or CD-R.
Sonic’s AuthorScript has components to handle
all of these functions. These include:
Navigation engine - Converts simple navigation
commands into the complex navigation structures
that the DVD/SCVD/VCD-Video formats specify.
File conversion engine - Encodes and formats
video, audio and still assets into the formats required
by DVD/SCVD/VCD (MPEG-1, MPEG-2 video compression,
Dolby Digital audio compression, sample rate conversion
and PCM audio formatting)
File analysis engine - Analyzes bit-rate
and legalizes files to ensure DVD/SCVD/VCD format
compliance
Multiplexing engine - Multiplexes the DVD/SCVD/VCD-legal
video and audio into DVD/SCVD/VCD-Volumes.
Formatting engine - Controls output of the
DVD/SCVD/VCD-Volumes to hard disk or directly to
DVD-R, or CD-R. |
