Chapter 11: Effects and transitions

You can correct, improve, and otherwise modify your assets with any of the dozens of effects provided in Premiere Pro.

Working with effects

Premiere Pro includes a variety of audio and video effects that you can apply to clips in your video program. An effect

can add a special visual or audio characteristic or provide an unusual feature attribute. For example, an effect can alter

the exposure or color of footage, manipulate sound, distort images, or add artistic effects. You can also use effects to

rotate and animate a clip or adjust its size and position within the frame. You control the intensity of an effect by the

values that you set for it. You can also animate the controls for most effects using keyframes in the Effect Controls

panel or in a Timeline panel.

Premiere Pro has Fixed effects and Standard effects. Standard effects generally affect clip image quality and

appearance, while Fixed effects adjust clip position, scale, movement, opacity, speed, and audio volume. By default,

Fixed effects are automatically applied to every clip in a sequence, but they do not change to the clip until they are

manipulated.

You can create and apply presets for all effects. You can animate effects using keyframes and view information about

individual keyframes directly in a Timeline panel.

Note: Premiere Pro can process all effects at an 8 bits per channel (bpc) color depth in the RGB color space. Some effects

can be processed at either 16-bpc or

32-bpc floating-point depth and some in the YUV color space. Choose File > New >

Sequence. Select the Video Rendering tab and then select the Maximum Bit Depth option to have Premiere Pro process

an effect at the highest possible quality. Keep in mind that this option uses lots of processing power.

About Fixed effects

Every clip you add to a Timeline panel has Fixed effects pre-applied, or built in. Fixed effects control the inherent

properties of a clip and appear in the Effect Controls panel whenever the clip is selected. You can adjust all of the Fixed

effects in the Effect Controls panel. However, the Program Monitor, Timeline panel, and Audio Mixer also provide

controls that are often easier to use. The Fixed effects include the following:

Motion Includes properties that allow you to animate, rotate, and scale your clips, adjust their anti-flicker property, or

composite them with other clips. (To adjust the Motion effect in the Program Monitor, see

“Adjust position, scale, and

rotation” on page 280 and “Animate motion in the Program Monitor” on page 282.)

Opacity Lets you reduce the opacity of a clip for use in such effects as overlays, fades, and dissolves. (To adjust the

Opacity effect in a Timeline panel, see

“Adjust the opacity of clips” on page 416.)
