Editor’s note: The following tip on changing keyframe interpolation in Motion 3 is excerpted from Apple Pro Training Series: Motion 3 by Damian Allen, Mark Spencer, Bryce Button, Tony Huet. published by Peachpit Press. Changing Keyframe Interpolation From: Designing and Animating Motion Graphics in Final Cut Studio 2; pgs. 382-385 To make the motion more dynamic, you want the mountains to move very quickly into the frame and slowly recede into the distance. Modifying the keyframe interpolation will allow you to achieve this effect. 1. Go to Frame 1. 2. Click the Animation menu for the X Position parameter and choose Show in Keyframe Editor. Motion opens the Keyframe Editor, and the selected parameter is automatically loaded with its keyframes, ready to be edited. This is a great feature, and it saves you a lot of time searching through dozens of parameters for the one parameter you want to edit. Rather than repeat the process for the Y and Z parameters, you'll have Motion display them automatically. 3. Just below the Keyframe Editor tab, click the Show pop-up menu. You'll see a list of options. In Motion, you can customize sets of curves for quick access by dragging parameters from the Inspector into a curve set. For example, if you're continually adjusting the blur and color of an object at the same time, you might want to create a curve set with just these two parameters modified. In this case, you'll use a predefined curve set. 4. Choose animated. When animated is chosen, only parameters of the currently selected object that already have keyframes will appear. Notice that the Keyframe Editor also has a keyframe diamond to the right of each parameter's label. Clicking the diamond will open an Animation menu similar to the one found in the Inspector. Tip: Several commonly used parameters and curve sets are listed and have single-letter shortcuts. For example, if the Keyframe Editor window is active and you press U, all of the animated properties of the selected layer(s) will be displayed. You can also create your own curve sets. For more information, see "Show Pop-Up Menu" in the Motion manual. 5. Click the Animation menu for Transform Position X. The Animation menu that appears is similar to the one found in the Inspector, but it has a few extra features. Here you can choose how Motion repeats the pattern laid out by your keyframes before the first keyframe in your curve (Before First Keyframe) and after the final keyframe (After Last Keyframe). You can also "thin" your keyframes using the Reduce Keyframes option. This resamples the number of keyframes to create a smoother curve. 6. Click outside the Animation menu to exit it. After that brief detour, let's get back to modifying the layer's motion. 7. Click the Fit Curves button in lower left corner of the Keyframe Editor. 8. Drag the zoom slider slightly toward the right to zoom out so that you can see the keyframes at frame 15 and 151. 9. Drag the scroll bar at the base of the Keyframe Editor to center the keyframes, if necessary. 10. Drag a marquee around all of the keyframes. 11. Control-click any one of the keyframes and choose Interpolation > Linear 12. Resume playback. The Mountains-far layer animates at a constant speed. This is OK for the start of the animation, but not for the editing. You'll adjust that in the next exercise. 13. Stop playback. (Note: You may need to repeat steps 7 through 9 to re-center the keyframes after playback.) Excerpted from Apple Pro Training Series: Motion 3 by Damian Allen, Mark Spencer, Bryce Button, Tony Huet.
