Audio Components in Compound Clips

Audio Components in Compound Clips

Audio Components in Compound Clips Manipulate audio components in compound clips based on each clip’s role.

Overview

When you reference a compound clip in a timeline, you can manipulate its audio components based on the clip’s role. By default, Final Cut Pro merges components from the compound clip with the same main role into a single component. Override this behavior to see the individual subroles by setting the ref-clip element’s useAudioSubroles attribute to 1.

In the code listing below, the ref-clip element references a compound clip, created from the clip from the first clode listing in the Compound Clip Media page. Because the useAudioSubroles attribute is set to 1, all subroles are accessible. The example applies Rumble Reducer effect on the two components with the dialogue subroles. The volume on the component with the music.music-1 subrole is turned down by 6dB.

<ref-clip name="MyCompoundClip" ref="r1" duration="5s" useAudioSubroles="1">   <audio-role-source role="dialogue.dialogue-1">
      <filter-audio ref="r6" name="Rumble Reducer" />
   </audio-role-source>
   <audio-role-source role="dialogue.dialogue-2">
      <filter-audio ref="r6" name="Rumble Reducer" />
   </audio-role-source>
   <audio-role-source role="music.music-1">
      <adjust-volume amount="-6dB" />
   </audio-role-source>
</ref-clip>
