Correct excessive shake and rolling shutter issues
You can smooth a clip’s shaky footage by correcting the stabilization, rolling shutter, or both.
The stabilization feature in Final Cut Pro reduces the camera motion in your video so that shaky
parts can be played back more smoothly. At any time, you can turn off stabilization for any clip so
that it plays as originally recorded.
Many camcorders and still cameras include CMOS image sensors that expose the picture they’re
recording progressively, instead of all at once. As a result, if the camera moves a lot during recording,
or if the camera is recording fast motion, image distortion can occur. This causes the picture to appear
wobbly or skewed. Final Cut Pro has a rolling shutter feature that can reduce this motion distortion.
Fix a clip with excessive shake or rolling shutter distortion
1 If the clip is not already in your project, add it to the Timeline and select it.
Note: These operations act on whole clip selections, not on range selections. To get the highest-
quality and fastest results, isolate the problem section by cutting the clip with the Blade tool in
the Timeline. Then apply the correction to just the video footage that needs correcting.
2 To open the Video inspector, click the Inspector button in the toolbar (shown below), and click
the Video button at the top of the pane that appears.
3 In the Video inspector, do any of the following:
•
To reduce the shake: Select the Stabilization checkbox.
•
To reduce rolling shutter distortion: Select the Rolling Shutter checkbox.
When you turn on Stabilization or Rolling Shutter, its checkbox turns blue.
4 To view the fix, play the clip in the Timeline.
To turn off stabilization or rolling shutter corrections for a clip, deselect the Stabilization or
Rolling Shutter checkbox.
You can refine the corrections by adjusting the stabilization settings or the Rolling Shutter
Amount setting.

You can adjust how much of a correction is applied by the stabilization feature.
The stabilization feature has two independent phases:
•
When you apply the stabilization feature to a clip, Final Cut Pro analyzes the pixels in
successive frames to determine the direction of camera movement.
