Animating a camera




Adding an adjustment layer

A simple reflection is pretty good, but a blur would make it look more realistic. You’ll use an adjustment layer to apply a blur effect. Effects applied to an adjustment layer affect all the layers beneath it.

1Choose Layer > New > Adjustment Layer. After Effects adds a new adjustment layer at the top of the layer stack.

2Move the Adjustment Layer 1 layer below the Ground layer in the Timeline panel. Moving the adjustment layer below the Ground layer ensures that it will affect only the reflection and Backdrop layers.

3With the Adjustment Layer 1 layer selected, choose Effect > Blur & Sharpen > Directional Blur.

4In the Effect Controls panel, change the Blur Length to 20. Leave the Direction setting at its default, as the reflections are perpendicular to the floor.

5Lock the Adjustment Layer 1 layer to prevent any accidental changes to it.

6Choose File > Save to save your work so far.

In Lesson 11, you created a camera layer, Camera 1. So far, that camera has been steady. Now, you’ll animate the camera, so that it begins far from the 3D objects and moves closer to them as the movie progresses.

1Go to 4:00 in the Timeline panel. This is the point where the camera will come to rest, after it’s moved closer to the subject.

2Select the Camera 1 layer in the Timeline panel, and press P to reveal its Position property.

3Press the Shift key as you press A to reveal the Point Of Interest property for the Camera 1 layer as well.

4Click the stopwatch icons for the Position and Point Of Interest properties to create keyframes for each.

You’ve set the keyframes for the end of the camera movement. Rather than starting the camera movement at the beginning of the time ruler, you’ll begin at 0:10, so that viewers have a moment to orient themselves before the camera begins to zoom in.

5Go to 0:10 in the Timeline panel.

6Change the Point Of Interest values to 360, 240, 0, and the Camera 1 Position values to -185, 132, -3000. Now the camera is much farther from the objects and the book is centered in its view.



7Shift-click the Point Of Interest and Position property names to select all the keyframes for the layer, and then choose Animation > Keyframe Assistant > Easy Ease.

8Press the spacebar to preview your work so far. Press the spacebar again to stop the preview.

9Hide the Camera 1 layer properties.
