Adobe Premiere Pro CS5 features more than 140
video
eff ects. Most eff ects come with an array of parame-
ters, all of which you can
animate
—have them change
over time—by using precise keyframe controls.

LESSON 9
Adding
Video Effects
Getting started
Video effects let you add visual flair to your project or repair technical issues in
your source footage. Video effects can alter the exposure or color of footage, distort
images, or add artistic style. You can also use effects to rotate
and animate a clip or
adjust its size and position within the frame.
Adding video effects is easy: You can drag an effect to a clip, or you can select
the clip and drag the effect to the Effect Controls panel. You can combine as
many effects
as you want on a single clip, which can produce surprising results.
Moreover, you can use a nested sequence to add the same effects to a collection
of clips.
Virtually all the video effect parameters are accessible within the Effect Controls
panel, making it easy to set the behaviors and the intensity of those effects. You can
add keyframes independently to every attribute listed in the Effect
Controls panel
to make those behaviors change over time. In addition, you can use Bezier curves
to adjust the velocity and acceleration of those changes.
Adobe Premiere Pro has two types of effects: fixed and standard. 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
the clip until they are manipulated.
When one of the supported video adapters is installed in the host computer, the
Adobe Premiere Pro Mercury Playback Engine uses the graphics processing unit
(GPU) to play back sequences. GPU acceleration offers the following benefits:
