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 (the Audio button) and then click the RAM preview button (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.
