Changing the Position of a Keyframe on the Timeline
After a keyframe is created, you can easily move it backward or forward in time on the keyframe track.

To Move A KEYFRAME ON THE TIMELINE:

		Select a filter in the Obsolete folder in the Video Effects palette.
		From the pop-up menu in the palette, select Show Selected. This will enable you to see and apply the selected filter, as shown in the illustration.

Not only can you move new keyframes, you can also reposition the first and last keyframes on the keyframe track of a clip. If you move the first keyframe on a clip forward in time, the effect won’t begin until the frame with that keyframe is played. Concurrently, if you move the last keyframe backward in time, when the clip is played, the effect will end when that keyframe is played, even if it’s shorter than the duration of the clip.

FIGURE 10-9

In Figure 10-9, the first and last keyframes were moved on the timeline. When the first keyframe is moved forward or the last keyframe is moved backward, the gray keyframe line turns black before and after the first and last keyframe. Additionally, the diamond turns into a half-black/half-white icon. The black line indicates the absence of an effect. The two-toned diamond alerts you to the fact that the first or last keyframe begins or ends before the natural duration of the clip.

To Delete A KEYFRAME:

		Navigate to the keyframe either with the previous/next arrows on the track or position the Edit line over the keyframe.
		Click the Add/Delete Keyframe box in the track. When the box is empty, no keyframe appears. When the box is checked, it indicates a keyframe where the Edit line is positioned.

As you can see, you can create thousands of incredible animated effects in Premiere on a single clip. Things become even more interesting when you animate more than one effect on a clip.[an error occurred while processing this directive]

Adding and Animating Multiple Keyframes on a Clip with Multiple Effects

Earlier in this chapter, we set more than one effect on a clip. Now that you’ve become familiar with keyframes and how they work, you’re probably curious to know if you could animate keyframes on multiple effects. The answer is an unequivocal yes.

FIGURE 10-10
Two effects and multiple keyframes have been added to a clip

In Figure 10-10, two effects are on the clip named artbeatsGlide.mov. The effects used are Bend and Color Balance. In addition, four keyframes are on the Bend effect and three keyframes are on the Color Balance effect. On each keyframe in each effect, the parameters of the effect are changed in the Effect Control palette.

The Bend effect as you can see, distorts the clip and creates a wave-like effect by altering the horizontal and vertical pixels. The Color Balance effect adds or sub-tracts red, green, and blue from the clip, enabling you to create a custom-colored image. Both effects can be adjusted with various slider controls.

To Add MULTIPLE KEYFRAMES WITH MULTIPLE EFFECTS TO A CLIP:

		Select a clip-and-drag effect on to the clip from the Effects palette.
		Set keyframes on the clip and change the parameters of the effect on selected keyframes.represents the numerical value of the slider.
		Repeat this process for another effect on the same clip.
		Toggle back and fourth from one effect to another on the same keyframe track by clicking the pop-up arrow in the left corner. The currently displayed effect is the one on which you can set and modify the keyframes (see the illustration).


	NOTE If you’ve worked in Photoshop, many of the Premiere effects should appear familiar to you, like the Noise, Distort, and Blur effects. In Photoshop, they’re called filters and they can be applied to still images. Equivalent filters in Photoshop, and Effects in Premiere will, for the most part, yield the same visual outcome. So, familiarity with one application can boost your learning curve of the other

To Disable AN ANIMATION EFFECT ON A CLIP:

Click the Stopwatch icon in the Effect Controls palette for that particular effect.

Adding and Animating an Effect on a Still Image
So far, you’ve been looking at animating effects on video clips. You can also animate still images in the same way. Figure 10-11 shows a still image on Video Track 1 and another on Track 2. Both these images have animation effects applied.

The clip on Video Track 1 has a Bevel Edges effect applied to it and the clip’s keyframes change over time. The effect doesn’t begin until about one quarter of the way into the clip, as indicated by the black line on the keyframe track. The Bevel Edges effect creates a three-dimensional raised image. In the Effect Controls palette, you can control the thickness, angle, and intensity of the bevel.

FIGURE 10-11
Two Photoshop files have been animated on Video Track 1 and 2

The clip on Video Track 2 has a Polar Coordinates effect applied for the duration of four keyframes. This effect creates interesting distortions by moving the X and Y coordinates of each pixel to its polar opposite X and Y coordinate. You can adjust the percentage of distortion from a slider in the Effect Controls palette. The Clip on Video Track 2 also has a fade applied to it. This enables you to see through the end of the first clip on Video Track 1 and the beginning of the last clip on Video Track 2. You can see the fade handles if you click the Opacity Rubberband icon to the left of the track.

So you can create some truly dynamic effects with still images as well as video clips in Premiere.

QuickTime Effects

You might have noticed that one of the folders in the Effects palette is a QuickTime folder. QuickTime effects are available to those systems that have versions of QuickTime 4.0 and later installed. A great number of QuickTime effects are already available as Premiere Effects, but they are certainly worth a look because you never know what you may find in here that may be of interest to you.

QuickTime Effects are applied from a dialog box. The Sepia tint selected in the Select Effect dialog box in Figure 10-12 casts a Sepia tone over the entire clip, using Sienna, White, and Black tonal values. You can also select another tint from the Tint Type pop-up, such as Black and White, X-ray, and Cobalt.

You can add more than one QuickTime effect the same way you would add multi-ple effects. To do so, simply drag another copy of the QuickTime effect on to a clip. You’ll see the additional QuickTime effect appear in the Effect Controls palette. On the Mac, you’ll also see the specific name of the QuickTime effect in the palette.

As you can see, effects are tremendously easy to apply, animate, and manipu-late. Often, the name of the effect indicates what it looks like. Picking an effect sometimes is like shopping for wallpaper. You bring one up, try it out, and either toss it or love it, and it helps jazz up your production. After you experiment with effects, you’ll become familiar with their different categories and outcomes.

In the next chapter, we dive in to sound in Premiere to learn how it works. As you will see, there’s a lot you can do with sound in Premiere to enhance a production.
