About This Document

This document describes components of the Motion XML file format. In particular, it provides information about XML elements of the Motion scene graph. (A Motion scene graph specifies the objects in a Motion project, their attributes, the media files they incorporate, and their dependencies on other Motion objects.)

You can use the information in this document to directly edit the XML specification of a Motion scene graph and thus modify a Motion project offline. Possible modifications include changing scene object parameters, replacing media files, and editing text objects. You might also develop a utility that lets you automate modifications to Motion projects.
