A Tour of Adobe Premiere > Adding special effects to a video clip

Adding special effects to a video clip

Premiere 5.0 lets you create many different kinds of special effects using video filters. For the last clip in the video program, you'll add the Camera Blur effect, which blurs a clip as if it were leaving the focal range of the camera.

Select the Finale.mov clip in the Timeline window.

Choose Clip > Filters.

Move the Filters window so that you can see both it and the Monitor window.

In the Filters window, select Camera Blur from the Available column, and then click the Add button.

The Camera Blur control window appears, displaying the first frame of the Finale.mov clip.

Drag the slider bar to zero, and then click OK.

The Camera Blur filter appears in the Current column of the Filters window. Filters listed in this column are applied to the currently selected clip.

To create an effect of changing focus, you can vary the Camera Blur effect over time. To do this, you set keyframes. A keyframe specifies a control value at a specific point in time.

The lower portion of the Filters window now displays a timeline, representing the duration ofthe Finale.mov clip. The triangular keyframes at each end of the timeline control when the effect begins and ends, and with what amount of blurring. Since you'd like the blurring to start about midway through the Finale.mov clip, you move the first keyframe. Moving a keyframe scrubs the clip in the Program view of the Monitor window.

Arrange the Filters window so that the program view in the Monitor window is visible. Then drag the first keyframe (the triangle on the left) to the right until you reach the point in the clip where the bikes are perpendicular to the camera.

Click the Edit button.

Make sure the slider is set at zero. Click OK.

Now you'll create a new keyframe and increase the amount of blurring.

In the Filters window, click in the middle of the two keyframes.

The Camera Blur Settings edit box appears.

Drag the slider bar until the Blur is at 80%, and then click OK.

In the Filters window, you can now see the triangle indicating the new keyframe you just created. Now you'll position this keyframe at an exact time.

Drag the keyframe you just created until the timecode reads 00:00:25:00 (25 seconds).

Now select the last keyframe (the triangle at the far right) and click Edit.

Once again, drag the slider bar until the Blur is at 80%. Click OK.

In the Filters window, click OK.

Let's briefly review what you've just done. By setting three keyframes—the first at 0%, the second at 80%, and the third at 80%—you have specified that the Camera Blur effect begins at 0% at the point in time you specified, increases to 80% at 25 seconds, and then remains at 80% for the duration of the clip.

Why not just use two keyframes—the first at 0% and the last at 80%? Premiere always creates a linear change between keyframes. Therefore, if you used only two keyframes, the blurring would gradually increase over the duration of the clip. This is not the effect you want; rather, you want the blur to happen fairly quickly, and then remain at that level for its duration.

Preview your work again.

Drag the right end of the work area bar so that it aligns with the end of the Finale.mov clip. Press Enter (Windows) or Return (Mac OS).

It's starting to look like something now!

Save the project.
