DVD authoring is the process of creating a DVD video that can be played on a DVD player, using software that meets the specifications established by the DVD Forum. It is the second step in producing finished DVDs, following movie creation and preceding manufacturing. Authoring involves designing artwork, user menus, chapter points, commentaries, and playback options. Although distinct from MPEG encoding, many authoring programs include built-in encoders, while separate encoders may be used for higher quality. Most applications focus on video DVDs, not DVD-Audio, and stand-alone DVD recorders offer basic authoring with limited menu customization, varying by model and brand.
The DVD specification
To develop a DVD application (software or hardware), one must first license the particular book of DVD specifications from DVD Format/Logo Licensing Corporation. The different DVD formats have different books. Each book contains hundreds of pages and costs approximately $5000. After obtaining this license, the developer must become a licensee, which requires an additional fee. Without becoming a licensee, the book can be used only for reference, not for actual creation of DVD applications.
The DVD specifications were written in Japanese and then translated to other languages such as English. This process has resulted in text that can be difficult to interpret, and to this day, many companies interpret various parts of the specifications in different ways. This is the primary reason DVD players from different manufacturers do not always behave identically.
Applications
Many different DVD authoring applications have been created. Many high-end authoring applications evolve in-house in companies such as Matsushita, Philips, Sony, and Toshiba. Such companies strictly forbid the sale of their systems outside each company: internal and DVD laboratories or movie studio partners use them to produce DVDs for customers.
Daikin, a large Japanese air conditioning and refrigeration contracting company, developed Scenarist, a high-end DVD authoring software package. Daikin has partnered with Sonic Solutions for development and marketing in the United States. The software was translated to English and has since become the standard for DVD production in Hollywood. Like the other high-end and very expensive systems, it conforms to the DVD specifications more closely than other software. In 2001, Sonic Solutions acquired the DVD authoring business, including ReelDVD and Scenarist, from Daikin and now sells Scenarist.
Sonic, a United States corporation, has a major share in the market for selling DVD-authoring tools. They previously manufactured computer based audio recording applications, but realized that at some point DVD recorders would become as widely available as CD recorders and that there was no affordable application for the home market or that DVD recorder makers could license as an OEM. At that time, all DVD authoring applications cost many thousands of dollars.
Sonic developed DVDit, an application that started selling below $500.1 It used only a small part of the whole DVD specification and presented it in a form that didn't require any knowledge of internal DVD structure. Later, this form became the building block of many other simplified consumer DVD applications. OEM licensing allowed Sonic to very soon become a major player. Sonic is now part of Rovi Corporation.
