Workshop
The Workshop consists of quiz questions and answers to help you solidify your understanding of the material covered in this hour. You should try to answer the questions before checking the answers.
Quiz
| 1: | What is the visual effect of a movie that has a keyframe in every frame?
It might have no visual effect.
| | 2: | If you set the frame rate to 2 fps, what is the visual result?
The animation looks jumpy. You see the blank (black) pauses between frames. You can see subliminal messages between the frames.
| | 3: | If a document's properties are set to a frame rate of 60 fps, how long will it take to reach Frame 90?

Quiz Answers| A1:
| C. Many factors besides how frequently keyframes appear affect how an animation looks. First, the nature of the content has more impact than how many keyframes you have. You could have very similar or very different content onscreen for each keyframe. Also, frame rate affects how an animation appears. | | A2:
| A. A frame rate of 2 fps is slow enough for you to notice the still frames, but the visual effect is jumpiness. (In fact if the contents of each frame is the same you won't see any changes.) The pauses between frames are just that—pauses—not black frames. | | A3:
| B. It's very unlikely that your computer can actually display 60 fps if the animation is particularly complex. It will probably take longer than 1.5 seconds to display all 90 frames. If your computer could keep up with the frame rate of 60 fps, it would take slightly less than 1.5 seconds because it has to travel only 59 frames from Frame 1. |
