Stabilize shaky clips

The stabilization feature in iMovie reduces camera motion in your video so that shaky parts can be played back more smoothly.

Many camcorders record video in a way that can cause image distortion if the camera moves a lot during recording (especially quick panning movements), or if the camera is recording fast motion. A video clip may appear wobbly or skewed in these instances. iMovie has a Fix Rolling Shutter feature to reduce this kind of motion distortion.

You can smooth a clip’s shaky motion by adding stabilization, fixing rolling shutter distortion, or both.
