Methods for runtime control of hierarchical objects are provided. Certain embodiments provide kinematics procedures in a media content, runtime environment. Making these procedures available in the runtime environment allows the variables of the kinematics procedures to be specified at runtime, for example by the end user or by a runtime-executed script. One exemplary method comprises receiving a hierarchical object for a piece of media in a media content authoring environment and providing the piece of media to one or more runtime environments. The piece of media provided to the runtime environments comprises both object information about the hierarchical object and kinematics procedural information for performing kinematics on the hierarchical object, such as procedural classes for performing inverse kinematics procedures based on runtime-provided end-effector and target point variables.
