Creating effects in Adobe Premiere Pro

Adobe Premiere Pro comes bundled with several dozen effects that enable you to perform simple and complex tasks, such as color correction, blurring and sharpening, audio enhancement, texturing, chroma keying, and a variety of other effects to enhance your edit. Having the ability to apply effects to clips in Adobe Premiere Pro yields efficiency in your workflow, because you don’t always have to use another program, such as After Effects, to create visual effects for your edit.

The most relevant and most important use of effects by far, for most editors, is the ability to adjust contrast and exposure and make color-correction enhancements. The Three-Way Color Corrector effect in Adobe Premiere Pro will be covered in Chapter 8.

Let’s do a simple exercise that demonstrates some of the general rules about effects in Adobe Premiere Pro.

Applying an effect to a clip

The first effect we will apply to a clip is Posterize Time.

Posterize time

  1. In the Timeline, go to prod_monitor_dancer.m4v, at 00:01:21:16.
  2. Play the clip. Notice that there is a lot of quick motion in this clip, which shows one of the dancers on a video monitor. A cool effect on a clip that has a lot of quick motion is the Posterize Time effect, because it allows you to decrease the frame rate of a clip, making quick movements appear briefly frozen in time.

  3. Go to the Effects panel.
  4. In the search field, type posterize time.
  5. Double-click Posterize Time to apply it to prod_monitor_dancer.m4v in the Timeline.
  6. Select the clip in the Timeline. Go to its Effect Controls panel.
  7. Verify the presence of the Posterize Time effect.
  8. In the Effect Controls, select the Frame Rate value. Change it to 6 (fps) and press Return (Enter).

  9. Play the clip in the Timeline.

Gaussian Blur

Since there will be a motion graphic over the final RED clip in the edit, it would be a good idea to blur this clip so that what will be the background for the motion graphic doesn’t distract from it. The Gaussian Blur effect is now accelerated in Adobe Premiere Pro, meaning that render times are drastically reduced, even when you’re working with RED footage. Depending on the capabilities of your GPU, you should be able to edit the effect during playback with ease, unlike with non-accelerated effects.

  1. Adjust the Timeline playhead to the final RED clip, prod_musicvid_raw02.R3D, and select the clip.
  2. In the Effects panel, select the search field and type gaussian blur.
  3. Double-click Gaussian Blur to apply it to the RED clip in the Timeline.
  4. Go to the Effect Controls panel.
  5. Select the value for Blurriness. Change it to 30 and press Return (Enter).

Scrub the playhead over the edit point. Note that the blur effect abruptly comes on. This would look better if the blur gradually came on. Achieving that requires keyframe animation, covered in the next lesson.
