Adobe Premiere Pro 2.0 [Electronic resources] نسخه متنی

1.

Select Window > Workspace > P Pro 2.0 CIB Workspace (or any other workspace) to get your workspace back in order.

2.

Delete the audio clips in the Timeline by marquee selecting them and pressing delete.

3.

Delete all the added audio tracks by right-clicking an audio track header, selecting Delete Tracks, checking Delete Audio Track(s) in the Delete Tracks window (shown in the next figure), and clicking OK.

Your sequence now has only two audio tracks: Audio 1 and Master (both are stereo).

4.

Drag Music 11 Stereo.wav from the Project panel to the Audio 1 track.

5.

Expand the track view by clicking the Collapse/Expand Track disclosure button.

6.

Click the Show Keyframes button () and select Show Clip Keyframes.

This lets you edit a clip's volume in the Timeline rather than using the Volume effect in the Effect Controls panel.

7.

Hover your cursor over the Volume Level Graphthe thin, horizontal yellow line between the left and right channelsuntil it turns into the Vertical Adjustment Tool () cursor and then drag that yellow line up and down.

8.

Ctrl+click the Volume Level Graph in four places evenly spaced along the yellow line. That places four keyframes on the volume line.

9.

Drag the first and last keyframes all the way to the left and right respectively to place those keyframes on the first and last frames of the clip.

10.

Drag the second and third keyframes left and right respectively to about two seconds from the beginning and two seconds from the end.

11.

Drag the start and end keyframes all the way to the bottom of the clip view to create a fade up and a fade out.

12.

Play the beginning and end of the clip to see how this works.

13.

Right-click on the second and third keyframes and select Ease In and Ease Out respectively.

1.

Make sure the Music 11 Stereo clip is selected on the Audio 1 track and open the Effect Controls panel. Twirl down the Volume disclosure triangles and widen the Effect Controls panel so you can see its timeline.

If the timeline is not open, click the Show/Hide Timeline View chevron button. Make note of a few things:

• Bypass This is something you haven't seen up to this point because only audio effects have this option. For the Volume effect, turning on Bypass at any point in the clip (Bypass is keyframeable) switches back to the clip's original volume level. You can use Bypass to switch any audio effect off and on any number of times within a clip.

• Level The only adjustable parameter.

• Keyframes All the keyframes and Keyframe Interpolation methods (hourglass icons) you applied to the clip in the Timeline show up in the Effect Controls timeline.

  
  

Adobe Certified Expert exam objective

Describe the options and process required when working with fixed effects. Author's note: Volume is the second of the three fixed effects. You worked with Motion earlier in the book and you will work with Opacity later.

2.

Adjust some keyframes and their parameters. Click Bypass and experiment with that.

3.

Marquee select all the keyframes in the Effect Controls timeline and press Delete.

4.

Drag the Constant Power audio transition (Audio Transitions > Crossfade) to the beginning of the clip on the Timeline.

5.

Click the transition rectangle on the clip to select it and view its parameters in the Effect Controls panel.

6.

Change the duration to three seconds.

That gives you a nice fade in.

7.

Do the same for the end of the clip and you have a fade out.

Replace the clip on the sequence with Audio 4a.aif and Audio 4b.mp3.

8.

Trim the end and beginning of the clips respectively to give them tail and head frames for a smooth transition.

9.

Drag Constant Power to that edit point and listen to how that works.

10.

Replace Constant Power with Constant Gain and listen to it.

Constant Gain changes audio at a constant rate in and out as it transitions between clips. This can sometimes sound abrupt. Constant Power creates a smooth, gradual transition, like a video cross dissolve. It decreases audio for the first clip slowly at first and then quickly falls off at the end of the transition. For the second clip, this audio crossfade increases audio quickly at first and then more slowly as it reaches the end of the transition. Constant Power is the default audio transition. Rely on it for most transitions. But your ears are the best judge. In this particular case, you might prefer Constant Gain.
