Abstract
An apparatus includes at least one processor; and at least one memory including computer program code; wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to: provide an animation timing extension; wherein the animation timing extension links a graphics library transmission format animation to timed metadata and a metadata track of the timed metadata; wherein the metadata track of the timed metadata is listed with an object associated with moving picture media; and align at least one timeline of the moving picture media with at least one timeline of the graphics library transmission format animation; wherein a sample of the metadata track is used to manipulate an animation event.

An apparatus comprising:
- at least one processor;
- and
- at least one non-transitory memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- provide an animation timing extension;
- wherein the animation timing extension links a graphics library transmission format animation to timed metadata and a metadata track of the timed metadata;
- wherein the animation timing extension references an accessor, the accessor describing a buffer where animation timing data is available, and wherein sample data from an animation timing track is provided to the buffer, and a change in the buffer triggers a change of state of the graphics library transmission format animation;
- wherein the metadata track of the timed metadata is listed with an object associated with moving picture media;
- and
- align at least one timeline of the moving picture media with at least one timeline of the graphics library transmission format animation;
- wherein a sample of the metadata track is used to manipulate an animation event.

An apparatus comprising:
- at least one processor;
- and
- at least one non-transitory memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- provide a utility to align:
- graphics library transmission format temporal media information that describes an animation timeline;
- moving picture temporal media information that describes a moving picture timeline;
- and
- global runtime temporal information that describes a global application timeline;
- wherein the alignment utilizes at least one graphics library transmission format file, a base media file format, or a sample to synchronize the graphics library transmission format temporal media information and the moving picture temporal media information with the global runtime temporal information;
- and
- manipulate a plurality of animations within a graphics library transmission format animation array simultaneously;
- wherein the graphics library transmission format animation array is associated with the at least one base media file format item or at least one base media file format track containing at least one other sample.
