Correcting Blurry or Distorted Video

Another problem that can occur when you record video is blurry images caused by quick movements of the camera while recording, which is called rolling shutter distortion. iMovie can reduce this distortion with its Rolling Shutter feature.

  1. In the Event Browser or the movie timeline, select a clip with blurry or distorted video by clicking it.

  2. Click the Adjust button.
  3. This displays the Adjustment bar above the Viewer. Click the Shaky Video button to display the Stabilization options.

  4. Select the Fix Rolling Shutter check box. The Fix Rolling Shutter check box displays with a red dash indicating that iMovie is applying this adjustment to the video. Based on the length of the video, this can take some time.

  5. When iMovie is done applying the Rolling Shutter adjustment, the Fix Rolling Shutter check box displays with a check mark.

  6. Preview the adjusted movie in the Viewer by moving your mouse into the Viewer, which causes the Playback options to display, and clicking the Play button to play the movie.

  7. To set the amount of Rolling Shutter adjustment to apply, click the Fix Rolling Shutter menu and choose the amount of adjustment you need. iMovie applies the new amount of Rolling Shutter adjustment to the video clip. Preview the movie in the Viewer to see the new setting applied for the Rolling Shutter adjustment.

  8. If you want to remove the Rolling Shutter adjustment, click the Remove Stabilization Adjustments button.
