Reviewing iMovie’s effects

For a free program, Apple’s iMovie sure comes with a lot of great features, including some special effects that can quickly transform the look and feel of your video clips. Besides the effects that come with iMovie, you can add effects by installing plug-ins from Apple and third-party software vendors. To view a list of iMovie’s effects, click the Effects button. The Effects pane appears. To preview an effect, just click it in the list of effects. A small preview of the effect appears at the top of the Effects pane, using whatever video is located at the current position of the play head in the timeline.

• Earthquake: As the name implies, this effect shakes the video image as if an earthquake were happening. Use a short earthquake effect combined with the sound of a large thud when someone falls down in your video.
• Electricity: This one has a shocking effect on your video by creating a continuous lightning bolt in your video. Use this effect in conjunction with the Electricity sound effect in the Audio pane
  
• Fairy Dust: This effect looks more like a burning fuse to me, but the folks at Apple call it “Fairy Dust,” so who am I to argue?
• Flash: The Flash effect makes the video image flash periodically. Combine the Flash effect with the Earthquake effect to create a more disorienting scene, or combine it with the Aged Film effect to make your video look really old and deteriorated.
• Fog: Add some mystery to your scene with the Fog effect. This effect is a classic example of an image that is often easier to edit into your video via software than to actually photograph. Use the Fog and Black & White effects together for a film noir look.
• Ghost Trails: Slight ghost trails are added to moving objects in the video image. Here’s another effect that can be used to make a scene look disorienting.
• Lens Flare: Lens flares are bright spots or streaks that occur when the sun or another bright light source reflects on the camera lens. You need to avoid lens flares when shooting video, but sometimes you may want to add a lens flare to make a mostly-imaginary scene look “photographed.” Professional moviemakers often add “fake” lens flares to animated or computer-generated images to make the scene look more realistic.
• Letterbox: Simulate that Hollywood movie “widescreen” look with this effect, which puts a black bar across the top and bottom of the video image. Just keep in mind that the top and bottom of your video image will be cut off.
• Mirror: iMovie actually offers two Mirror effects that turn half your video picture into a mirror image of the other half. One Mirror effect reflects only horizontally; the other can reflect both horizontally and vertically.
• N-Square: Ever wonder how a housefly would see your video? The N-Square effect may show just that. This effect divides the screen into squares and copies the video clip to each square. You can adjust the number of squares from four up to 64 as shown in Figure.
• Rain: Add some fake weather to your scene with this effect. The fake rain drops added to a video clip by this effect show up much better onscreen than real rain, yet the scene still looks realistic. Use this effect in conjunction with the Rain sound effect in the Audio pane.
• Soft Focus: Simulate a soft filter on the camera with this effect. The Soft Focus effect works well in dream sequences, or to cover up blemishes on a video subject.
