Align audio to video
If you perform a split edit that extends the audio portion of a clip beyond the video portion,
you can quickly put the audio and video back into alignment so that the video and audio
start and end points match.
1. In the Final Cut Pro timeline, select the clips or components you want to align.
2. Choose Trim > Align Audio to Video.
If you select a component, the audio is aligned on both edges of that component. If you
select the edge of a component, only that edge is aligned.
Note: If you’re working on numerous split edits throughout your project, you might find
it convenient to show expanded audio by displaying audio roles in separate lanes. See
Organize the Final Cut Pro timeline with audio lanes.
Show trimming details in the Final Cut Pro viewer
For more accurate visual feedback on edits involving contiguous or connected clips, you
can see a “two-up” display in the viewer. For example, for a simple ripple edit, this two-up
display shows the end point of the left clip and the start point of the right clip.
This display is available for ripple edits, roll edits, slip edits, and slide edits, as well as for
trimming in the precision editor.
1. Choose Final Cut Pro > Preferences, or press Command-Comma (,).
2. Click Editing.
3. In the Timeline section, select the “Show detailed trimming feedback” checkbox.
The two-up display appears in the viewer whenever you use a supported edit type or
when trimming in the precision editor.
Tip: You can use the Option key to change the detailed trimming feedback display
on the fly. If detailed trimming feedback is enabled, press the Option key to disable
it. If detailed trimming feedback is disabled, press the Option key to switch the view
between the end point of the left clip and the start point of the right clip.
