Final Cut Pro offers two ways to copy effects between clips:
Paste Attributes: This command lets you copy selected clip attributes to another clip and provides more control over individual effects, settings, and keyframes. For example, you can copy video crop settings, audio pan settings, or keyframe adjustments.
Paste Effects: This command copies all of a clip’s effects to another clip and is the fastest way to copy effects and attributes.
You can also copy and paste individual keyframes from one parameter to another. See Copy and paste keyframes.
Copy selected clip attributes to another clip
Select a clip in the timeline, then choose Edit > Copy (or press Command-C).
Select the clip or clips to which you want to apply the attributes, then choose Edit > Paste Attributes (or press Shift-Command-V).
Do any of the following:
Apply all video or all audio attributes from the source clip: Select the Video Attributes or Audio Attributes checkbox.
Apply individual attributes: Select the checkboxes for the attributes you want to apply.
If you made any keyframe adjustments to the source clip, select one of the following in the Keyframe Timing section:
Maintain: Leaves the duration between keyframes unchanged.
Stretch to Fit: Adjusts the keyframes in time to match the duration of the destination clip.
Click Paste.
