Create animations using the Timeline
Last updated 6/15/2014
5 Drag each of the rectangles across the stage until the tail end of the skewed rectangle is visible.
At this point, most of the stage is covered by the color bars, with white triangles of the stage showing through at the
edges. Remem
ber to press the Shift key as you drag if you want to steady the bars’ vertical position.
6 With all the rectangles selected, in Properties click the Add Key Keyframe for Opacity button. Drag the playhead
back and forth to preview the animation. The opacity for each color bar is set to 100 percent at the 2 second point.
Scrubbing the playhead gives you a quick look at the action.
7 Drag the playhead to the 0:03 marker. This position represents the point 3 seconds into your animation.
8 Select each rectangle and then change the height (H property) to 300 px and the opacity to 50 percent. This has the
effect of making the rectangles grow, slicing vertically into one another, and at the same time start to blur. See Figure
25. Keep in mind, you may need to delink the W and H properties to change them independently.
9 Drag the playhead to the 0:04 marker. Then change each rectangle’s height to 500 px and the opacity to 0 percent.
The effect is that the rectangles keep growing and blur out of view.
