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.
