Abstract:
1. A method of defining a media editing application having a graphical user interface (“GUI”) for editing content on a computing device, the method comprising: to represent values of an attribute of a media content over a duration of time, defining a key-indexed geometry that spans along the duration and comprises a plurality of movable key indices at different locations along the duration to specify different values of the attribute at the different locations, wherein the change in the values of the attribute between any two key indices is represented with a geometric component connecting the two key indices that reflects the different attribute values of the attribute along the duration, wherein movement of a key index modifies the key-indexed geometry and modifies at least a subset of values of the attribute along said duration; for the key-indexed geometry, defining a collapsed representation that spans along said duration and comprises a plurality of key-index markers at the different locations without the geometric component connect each key indices, each marker having a key index for moving in at least a first direction with the marker to modify the location of the key index along the duration while maintaining the value of the attribute specified by the key index, and moving along the marker in a second direction that is neither parallel nor collinear with the first direction to modify the attribute value specified by the key index while maintaining the location of the key index along the duration; and defining at least one control for switching between displaying the key-indexed geometry and the collapsed representation.
