Effects can help you clean up your video or add special touches that amaze and astound your audience. What's really cool about effects is that you can add them to (or remove them from) any clip that you want. Effects don't permanently change your clips, so if you aren't happy with a result, you can simply delete the offending effect.
Adobe Premiere Pro comes with more than 50 effects built right in. Some of these effects may not seem immediately useful, but you may be surprised in a future project when what seems like the most obscure effect comes in handy. You can get a look at Premiere's effects by choosing Window --> Effects, or just click the Effects tab in the Project window. Expand the Video Effects folder to reveal the following 14 categories:
- Adjust: These seven effects let you tweak levels of color and light. You may find them useful for fixing color- and light-related problems in your video clips.
- Blur & Sharpen: These 11 effects run the gamut from blur to sharpen. The blur effects allow you to soften the outlines of things to simulate disorientation or suggest speed by unfocusing parts of the video image. The sharpen effects perform a variety of sharpening enhancements to an image. Use these effects to sharpen images that appear too soft.
- Channel: This category includes two effects. The Invert effect inverts colors in a clip. The Blend effect enables you to blend the colors of superimposed clips.
- Distort: This folder contains 13 effects that bend, twist, or exaggerate the shape and view of your video.
- Image Control: These ten effects change the way you view color in your clips. They can remove a color (or range of colors) from a clip, convert a color image to black and white, or adjust the overall tint of the image (useful if, for example, you want to transform an ordinary outdoor scene into an alien landscape).
- Keying: These effects let you control transparency in clips and perform compositing effects, such as bluescreening.
- Noise: You can use the Median effect — the only effect in the Noise category —to reduce noise in the video image. If you apply the more extreme settings, the image begins to look like a painting.
- Perspective: These four effects add a three-dimensional feel to your clips — for example, when you bevel the edges of the video image or create shadows.
- Pixelate: These three effects modify the pixels that make up your video image to create some unusual visual coloration and appearances. (Textures, anyone?)
- Render: The three Render effects let you simulate various properties of real light. One of the effects simulates lens flares — momentary bright circles that often occur in video footage when the sun reflects or glares on the lens. Well-placed simulated flares can be dramatic if you're depicting a sunrise or sunset.
- Stylize: These 12 effects create a variety of image modifications. With the Stylize effects, you can simulate video noise (on-screen "snow"), create clip mosaics, add texturized or windswept appearances to the image, and more.
- Time: The Echo effect creates visual echoes (or double-image) of a picture. The Posterize Time effect modifies the apparent frame rate of a clip. Use this effect to make it look like you dropped frames during capture or output even if you really didn't.
- Transform: These nine effects transform the view of your clip in a variety of ways. You can rotate the image in three dimensions, you can simulate a panning effect, or you can simulate a vertical-hold problem on a TV.
- Video: These three effects help correct video problems or prepare video for output to tape. You can apply the Broadcast Colors effect to clips when you want to filter out colors that aren't broadcast-legal, or you can use the Field Interpolate effect to replace missing fields knocked off the screen by interlacing. If you have a clip with many thin lines, the lines may flicker when viewed on a regular TV. Use the Reduce Interlace Flicker effect to soften the image and reduce the flickering problem.
