mx product range is its support for long format video and 3d elements

Director has always been designed to handle the widest possible range of multimedia formats. Unique in the MX product range is its support for long format video and 3D elements.
New capabilities exist for audio and video RealMedia, Windows Media, AVI and QuickTime 6, including MPEG4 streaming. Support for these formats is extremely flexible and durable, and makes for a powerful publishing toolset.
The most exciting feature introduced in Director version 8.5 was support for Shockwave 3D. With Director MX, you can import 3D models, textures and animations from virtually any other package, and manipulate 3D elements using Lingo scripts (below). The extended 3D capabilities include physics awareness, particle system effects, bones animation, cartoon rendering and motion manipulation, and should attract authors of gaming applications, educational suites, and so on.
Perhaps the most important development within this new release is support for the pervasive DVD format. Using Macromedia's 'author once, publish anywhere' commitment, you can seamlessly output to DVD, as well as the usual CD, internet and kiosk platforms.
Applications such as Adobe Encore DVD and Apple DVD Studio already allow for multimedia authors to build DVD interfaces and interactive applications, although anything truly exciting in this area has yet to be achieved. We can now expect that to change with Director's ability to create cross-platform enriched DVD content; you have the ability to embed DVD movie playback inside projectors, trigger events during movie playback, control navigation, etc. If this is your bag, look no further than Director.
