DVD authoring is the process of creating a DVD video capable of playing on a DVD player. DVD authoring software must conform to the specifications set by the DVD Forum. DVD authoring is the second step in the process of producing finished DVDs. The first step is the creation of the movie (or programme) and the second, the authoring, is the creation of artwork, user menus, insertion of chapter points, overdubs/commentaries, setting autoplay and/or repeat options, etc.〔http://ceiton.com/CMS/EN/CEITON-CTWS-mediabiz-DVD.pdf DVD Authoring workflow〕 The final step is the manufacturing (replication) process to mass-produce finished DVDs. Strictly speaking, DVD authoring differs from the process of MPEG encoding, but most DVD authoring software has a built-in encoder, although separate encoders are still used when better quality or finer control over compression settings are required. Most DVD-authoring applications focus exclusively on video DVDs and do not support the authoring of DVD-Audio discs. Stand-alone DVD recorder units generally have basic authoring functions, though the creator of the DVD has little or no control over the layout of the DVD menus, which generally differ between models and brands. ==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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DVD authoring」の詳細全文を読む スポンサード リンク
