Adding transparency

Previewing the effects

It’s time to preview all of the effects together.

1 Click the Destinations tab in the Timeline panel to switch to the main composition. Press the Home key or drag the current-time indicator to make sure you’re at the beginning of the time ruler.

2 Make sure the Video switch () is selected for both layers of the Destinations Timeline panel.

3 Click the Play button () in the Preview panel, or press the spacebar, to watch the preview. Press the spacebar to stop playback at any time.

Many TV stations display logos semi-transparently in the corner of the frame to emphasize the brand. You’ll reduce the opacity of the ID so that it can be used this way.

1 Still in the Destinations Timeline panel, go to 2:24.

2 Select the destinations_logo layer, and press T to display its Opacity property. By default, the Opacity is 100%—fully opaque. Click the stopwatch icon () to set an Opacity keyframe at this location.

3 Press the End key or drag the current-time indicator to go to the end of the time ruler (2:29), and change the Opacity to 40%. After Effects adds a keyframe. The logo appears, the words travel Europe fly in, and it all fades to 40% opacity.

4 Watch a preview of your composition by clicking the Play button in the Preview panel, by pressing the spacebar, or by pressing 0 on your numeric keypad. Press the spacebar to stop playback when you’re done.

5 Choose File > Save to save your project.
