Adobe Premiere Pro 2.0 [Electronic resources] نسخه متنی

Adobe Certified Expert exam objective

Describe the options and process required when working with Lesson 9. Fixed Effects are Motion, Opacity and Volume. Motion and Opacity are automatically available for all clips including still images and graphics. Volume is available for all clips with audio. I cover Opacity and Volume later in the book.

1.

Open Premiere Pro 2.0 to the Lesson 10 project and open the Lesson 10 Practice sequence.

2.

Switch to the Effects workspace (Window > Workspace > Effects).

3.

Click the Program Monitor, View Zoom Level drop-down list (highlighted in the next figure) and change the Program Monitor zoom level to 25%.

This is to help you see and work with the Motion effect's bounding box.

4.

Expand the Lesson 10 preset in turn (there are five in all).

6.

Drag the Lesson 10 Practice sequence and play that clip.

This is how the Motion effect you'll work on should look by the end of this mini-lesson.

7.

Twirl down the Motion disclosure triangle in the Effect Controls panel.

8.

Click the Position Toggle Animation stopwatch to turn off its keyframes.

9.

Click OK when prompted that the action will delete all keyframes.

10.

Click the Reset button (to the right of Motion in the Effect Controls panel). These two actions return Motion to its default settings.

1.

Drag the CTI anywhere in the clip so you can see the video in the Program Monitor.

2.

Click inside the Program Monitor screen.

That puts a bounding box with a crosshair and handles around the clip (as shown in the next figure) and activates the Motion Effect in the Effect Controls panel. Clicking on Motion or its Transform button () in the Effect Controls panel will also activate the clip bounding box in the Program Monitor.

3.

Click anywhere in the clip bounding box in the Program Monitor, drag this clip around and note how the Position values in the Effect Controls panel change.

4.

Drag the clip so its center is directly over the upper left corner of the screen and note the Position values in the Effect Controls panel are 0, 0 (or close to that depending on where you placed the center of the clip).

The lower right corner of the screen is 720, 480, the standard NTSC DV screen size.

6.

Drag the clip completely off the screen to the left as shown in the next figure.

7.

Fine-tune that adjustment by changing the Position values in the Effect Controls panel to -360, 240.

Since 360 is half of 720, this puts the right edge of the clip at the left edge of the screen frame.

8.

Put the CTI at the beginning of the clip (press Page Up or Home) and apply a Position keyframe there by clicking Position's Toggle Animation stopwatch.

9.

Drag the CTI to the center of the clip and change the Position values to 360, 240 (the center of the screen).

Changing the Position parameters adds a keyframe there.

10.

Put the CTI at the end of the clip (press Page Down, then the left arrow key).

11.

Change the Position values to 360, -240.

That puts the clip completely above the screen and adds a keyframe.

12.

Play the clip.

It moves smoothly on-screen, then slides off the top. You have created a path (if you don't see the path, click on

Motion in the Effect Controls panel to switch on its display). Make note of a few things (highlighted in different colors in the next figure):

• It's a curved path. Premiere Pro automatically uses Bezier curves for motion.

• The little dots describe both the path and velocity. Dots close together represent a slower speed, dots more spread out represent a faster speed.

• The little four-point stars are keyframes.

A Clip Motion Path (color added for emphasis): Red dots represent the Path (their spacing indicates relative Velocity), cyan dots are keyframes, yellow dots are Bezier handles and the magenta lines are the clip's bounding box.

13.

Drag the center keyframe in the Program Monitor (the four-point star/square) down and to the left.

Notice that the dots get closer together to the left of the keyframe and farther apart to the right.

14.

Play the clip and note that it moves slowly until the first keyframe then speeds up.

15.

Drag the center keyframe again, this time down and to the right (use the next figure as a reference).

That creates a parabola with evenly spaced dots on both sides, meaning the velocity will be the same on both arms of the parabola.

16.

Drag the center keyframe in the Effect Controls timeline first to the left, and then most of the way to the right.

17.

Play this clip and note how much slower it goes at the beginning and how much faster at the end.

It should behave the same way it did when you applied the Lesson 10-1 preset.
