You can associate a Uniform Resource Locator (URL) with a marker to create an automatic link to that site. After Effects embeds this information within certain kinds of movies, including Flash (SWF), Windows Media, and QuickTime movies. When these movies are played in a web browser, the embedded URL is recognized, initiating a jump to the specified URL. You can target a specific frame in the site.

You can also associate a chapter reference point with a marker. Chapter links are similar to chapters used in CD‑ROM and DVD discs. Like the chapters of a book, a chapter link divides a movie into segments. Chapter links are supported in QuickTime and Windows Media movies.

Adobe Encore can read chapter references in After Effects layer-time markers when you export to the AVI or MPEG-2 file format. To be compatible with DVD format, make sure that markers are at least 15 frames apart.

Flash Video cue points can each have any number of parameters, each with a name and a value. You can only add three parameters using the marker dialog box. To work with more than three parameters, use the scripting interface.

To convert selected properties to Flash Video cue point parameters in layer-time markers, choose File > Scripts > Convert Selected Properties To Markers.jsx. This script adds a layer-time marker on the layer at the same time as each keyframe for each selected property. The markers’ cue point parameters indicate the name of the property and its value at that time. If the selected property has an expression, a marker is created for each frame, with the values sampled at each frame.
