Chapter 4 Flashcards
How does Motion let you know that recording is enabled?
The Record button turns red and all keyframeable value fields in the Inspector turn red.
Which parameters of a layer or group are keyframed when recording is turned on and their values are changed?
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.
How many keyframes do you need to create animation?
To animate with keyframes, you need to have at least two keyframes with different values.
The position of a video is keyframed at 1:00 AND 5:00, but it does not move. Why?
Because the keyframes have the same value.
How do you open the Keyframe Editor?
Choose Window > Keyframe Editor or press Command 8.
How do you change the interpolation for a keyframe curve?
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.
How can you set the interpolation for a keyframe to Logarithmic?
In the Keyframe Editor, you can change the interpolation of the 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.
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?
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.
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?
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.
When setting keyframes manually, which do you do first-set the keyframe or change the value-and why?
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.
What parameters can be keyframed?
Any parameter of any layer, group or effect that has an Animation pop-up menu in the Inspector.
