Sudden Motion Sensor and video editing performance

Beginning with the PowerBook G4 (12-inch 1.5GHz), PowerBook G4 (15-inch 1.67/1.5GHz), and PowerBook G4 (17-inch 1.67GHz), PowerBook G4 computers feature a Sudden Motion Sensor.

If you have a computer with the Sudden Motion Sensor and you have video editing applications, such as Final Cut Pro, Final Cut Express, or iMovie that exhibit performance issues (like dropped frames), then temporarily turn off the Sudden Motion Sensor while working in those applications.
