Adding transparency
The logo should appear semitransparently in the corner of the frame during the presentation. You’ll reduce the opacity of the logo, scale it, and shift its position so that it can be used this way.
Still in the Explore Hawaii Timeline panel, go to 2:10.
Select the BlueCrabLogo 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 point in time.
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 Explore Hawaii show up, and it all fades to 40% opacity.
Go to 2:10, and press P to display the Position property and then Shift+S to display the Scale property, too. Click the stopwatch icons () to set initial keyframes for both properties.
Go to 2:25, and change the Scale to 25% and the Positon to 620, 410.
Click the Play button () in the Preview panel, press the spacebar, or press 0 on your numeric keypad to preview your composition.
Press the spacebar to stop playback when you’re done.
