Nesting compositions containing layer-time markers
If you add one composition to another, the original composition becomes a layer in the composition. All the nested
composition’s composition-time markers become layer-time markers in the timeline of the parent composition.
These markers are not linked to the original composition-time markers. Changes you make to the composition-time
markers in the original composition do not affect layer-time markers in the nested composition. For example, if you
remove one of the original composition-time markers, the corresponding layer-time marker for the nested compo-
sition remains in place.

To create a web link from a marker
When you create a marker, you can type a Uniform Resource Locator (URL) under Web Links in the Marker dialog
box to create an automatic link to that site. After Effects embeds this information within movies. When these movies
are included in web pages created by programs such as Adobe GoLive
®
, the embedded URL is recognized at playback,
initiating a jump to the specified URL. You can even target a specific frame within the site.
Web link markers work only with layer-time markers and supported output formats, such as QuickTime,
Macromedia Flash (SWF), and others.
1
Create a layer-time marker and then double-click it to open the Marker dialog box.
2
For web links, type the URL for the site.
3
To activate a specific frame in a site, type the file name of the frame for Frame Target and click OK.
To create a chapter link
You can also create a layer-time marker as a chapter reference point, 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 movies.
1
Create a layer-time marker and then double-click it to open the Marker dialog box.
2
For Chapter Links, type the chapter name and number (if available), and click OK.
To synchronize markers to audio
After Effects provides a quick way to add and label markers for significant points in a layer’s audio track, such as a
rhythmic beat in music or spoken words in dialogue. Once markers are created, you can use them to synchronize
video or other effects.
1
In the Time Controls panel, click the Audio button
and then click the RAM preview button
.
2
At the points in time where you want to add a marker, press the multiply key (*) on the numeric keypad to create
a layer-time marker.
3
When previewing is complete, double-click a marker you just created, type a descriptive label in the Comment
box (such as a word being spoken at that time), and click OK. Repeat for any other markers you added.
