Digital Fusion is a fully integrated, non-linear compositing and special effects post-production system for finishing, design and effects creation, used extensively in many feature films, HDTV productions, broadcast video, web-based/multimedia projects and more. Lua forms the basis of 'DFScript', an integrated scripting language added in Digital Fusion v4. This allows the automation of repetitive tasks within the program, as well as facilitating integration into other aspects of a post production facility, such as clip management, 3D renderer integration, EDL/conform integration etc.
