Lesson Review

  1. How does Motion let you know that recording is enabled?
  2. Which parameters of a layer or group are keyframed when recording is turned on and their values are changed?
  3. How many keyframes do you need to create animation?
  4. The position of a video is keyframed at 1:00 and 5:00, but it does not move. Why?
  5. How do you open the Keyframe Editor?
  6. How do you change the interpolation for a keyframe curve?
  7. How can you set the interpolation for a keyframe to Logarithmic?
  8. You want to set a keyframe at 3:15 for the scale of three layers that are each in different groups. How can you set it for all of them at once?
  9. When you set a keyframe with recording enabled at a frame that is not at the beginning of a layer, what does Motion do automatically?
  10. When setting keyframes manually, which do you do first—set the keyframe or change the value—and why?
  11. What parameters can be keyframed?


  1. The Record button turns red, and all keyframeable value fields in the Inspector turn red.
  2. All keyframeable parameters will be keyframed by default if you change their values with recording enabled. You can change the recording options by double-clicking the Record button and selecting the checkbox to record keyframes on animated parameters only.
  3. To animate with keyframes, you need to have at least two keyframes with different values.
  4. Because the keyframes have the same value.
  5. Choose Window > Keyframe Editor or press Command-8.
  6. In the Keyframe Editor, from the Animation pop-up menu, choose Interpolation. The submenu includes four interpolation options: Constant, Linear, Bezier, and Continuous. You can also Control-click a keyframe or a curve in the Keyframe Editor.
  7. In the Keyframe Editor, you can change the interpolation of individual keyframes along a curve by Control-clicking a keyframe and choosing an interpolation type. This technique provides access to five additional interpolation options: Ease In, Ease Out, Ease Both, Exponential, and Bezier.
  8. Command-click each of the layers to select them. Then click the Animation pop-up menu in the Properties Inspector for Scale and choose Add Keyframe, or click the keyframe icon.
  9. Motion automatically sets a keyframe at the beginning of a layer if recording is enabled when you change the value of a parameter at any other point in time.
  10. Always set the keyframe first and then change the value when setting keyframes manually; otherwise, the value will change for the entire duration of the layer, not just at the keyframe.
  11. Any parameter of any layer, group, or effect that has an Animation pop-up menu in the Inspector.
