CREATING DVD TITLES

The production process comprises of authoring, pre-mastering and manufacturing. Multimedia titles for DVD can be created using similar tools to those used for CD-ROM titles such as Macromedia Director, Flash, Java etc. Your target audience could be people with DVD installed in their computers which can simply act as data storage devices. Your options are limitless in what you can place on a DVD disc.

Where MPEG-2 video files are to be incorporated, DVD-Video authoring tools will also be required to encode the audio and video, add navigation and create the VOB files.

PRE-MASTERING AND TESTING

The authored files that you create are finalized using software that is designed to format the data using the UDF Bridge file system and according to the DVD specification.

For a hybrid disc, the DVD-Video and/or DVD-Audio files must be contained in the appropriate directories.

This finalizing process will result in a disc image, which should then be written to DLT (Digital Linear Tape) or DVD-R (DVD recordable) for archival transport to our Pre-Mastering work station. We can make final "check discs" for testing purposes (additional charges apply).

MANUFACTURING DVD DISCS

The manufacturing process is similar to that of CD-ROM where as a glass stamper is formed in order to produce a nickel stamper which in turn makes the DVD discs.

The final DVD disc can be a DVD-5, DVD-10 or DVD-9 depending on the data size and whether a double-sided disc is acceptable. DVD-9 and DVD-10 discs will require two DLTs, one for each side/layer
