add a transition effect

Our final step in creating the intro animation is to have its last frame move the Playhead in the main Timeline to the frame with the static background.

Add a keyframe in Frame 25 of the actions layer.

Click Scene 1 in the Edit Bar to exit symbol-editing mode. Save your file.

That's it. Our intro animation is complete. Press (Windows) or (Mac) to preview your work in the Flash Player window.
