Methods and apparatus provide for an abstract model interpreter that defines an abstract model to represent an interactive video. The abstract model is defined independent of any export format. An interface for the abstract model is created to concurrently manage interpreting the abstract model according to a plurality of different export formats. For example, the abstract model interpreter can map a feature of the interactive video, which is described in the abstract model, to a corresponding feature supported by an export format. The interface is thereby utilized to interpret the abstract model to create a formatted interactive video, which is a version of the abstract model compliant with an export format from the plurality of different export formats. The interface further provides an edit capability that allows a user to modify how the feature of the interactive video is to be supported by any of the different export formats.

Export of playback logic to multiple playback formats

A system traverses a directed cyclic graph to discover a relationship between a first object and a second object, and creates an alias. The alias represents the second object. The system replaces the relationship between the first object and the second object with the created alias, and creates a reference from the first object to the alias.

Methods and apparatus for using aliases to display logic

Novel techniques and tools for authoring multimedia compositions are presented. The novel techniques and tools allow an author of a multimedia composition to create a multimedia composition by dragging assets from a first window containing a project's unused assets and placing the assets into a structural relationship in a second window. The author may also remove assets from the structural relationship in the second window and return the assets to the first window of unused assets. The novel techniques and tools allow an author of a multimedia composition to better keep track of the assets to be used in the multimedia composition.

Construction of multimedia compositions

Methods and apparatus for arranging and aligning graphical objects are disclosed. The selection of a first graphical object in a graphical user interface is received, and it is determined if the first graphical object is located at a substantially minimal distance in a reference plane from a related second graphical object on the graphical user interface. If the graphical objects are not located at a substantially minimal distance from each other in the reference plane, the graphical objects are graphically arranged to substantially minimize the distance in the reference plane between them.
