Creating chapter links
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.
To create a chapter link:
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.
Nesting compositions containing layer-time markers
If you add one composition to another, the original composition becomes a layer in the
parent composition. All the nested composition's composition-time markers become
layer-time markers in the Timeline window of the parent composition. These markers are
not linked to the original composition-time markers: Changes you make to the compo-
sition-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 composition remains in
place. For more information about nesting, see "Organizing a project using nesting" on
page 265.
Adding markers synchronized 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.
To synchronize markers to dialogue:
1 In the Time Controls window, select 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 asterisk key (*) on the
numeric keypad to create a layer 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.
About After Effects Audio/Video switches
The Timeline window contains the Audio/Video Features and the Switches panels. By
default, these panels appear to the left (A/V Features) and right (Switches) sides of each
layer name, but you can hide a panel or arrange panels in a different order. For general
information about using panels, see "Default controls and panels" on page 66 and
"Optional panels" on page 66.
Use the switches to adjust the balance between display performance and display quality
during your work session, clicking switch icons for individual layers to turn them off or on.
You can also control them for selected layers by choosing Layer > Switches > command.
Check marks next to commands indicate that those switches are currently turned on.
