Align audio to video
At any time, you can align audio to video for clips or components in your project to make
the video and audio start and end points match. This clears any split edits you made.
You can select multiple clips or components.
1. In the Final Cut Pro timeline, select the clips or components you want to align.
2. Choose Trim > Align Audio to Video.
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.
Make roll edits in Final Cut Pro
A roll edit adjusts the start point and the end point of two adjacent clips simultaneously. If
you like where two clips are placed in the timeline but want to change when the cut point
happens, you can use the Trim tool to roll the edit point between the two clips. No clips
move in the timeline as a result; only the edit point between the two clips moves. No other
clips in the project are affected.
When you perform a roll edit, the overall duration of the project stays the same, but both
clips change duration. One gets longer, and the other gets shorter to compensate.
In the example above, clip B gets shorter while clip C becomes longer, but the combined
duration of the two clips stays the same.
You can see a “two-up” display in the viewer as you trim edit points in the timeline. This
display shows a more detailed view of each side of an edit point. See Show trimming
details in the Final Cut Pro viewer.
1. In Final Cut Pro, click the Tools pop-up menu in the top-left corner of the timeline and
choose Trim (or press T).
The pointer changes to the Trim tool
.
Tip: To switch to the Trim tool temporarily, hold down the T key. When you release
the T key, the tool reverts to the previously active tool.
