Jerk is a free iMovie plug-in that will make motion in a clip 'jerky' (and yes, we wrote this plug simply because we could give it this silly name), giving the clip a distinctively surreal, nightmarish quality. The plug-in works by repeating the same frame a specified number of times, thus effectively reducing frames per second (fps) from 30 (DV) to anything around 1.8. One use is to give your clip a distinct 'super-8' feeling (especially in conjunction with our 'flicker' plug-in). Since you can apply this effect to only parts of the clip, this can also create some really strange shearing effects when the frames shortly get our of sync.
