Chapter 18 - Elements of Motion
Formal design relationships we have created in still compositions are also active in animations. Repetition, symmetry, asymmetry, balance, and rhythm become enveloped in a new formal element: time. In the visual examples, forms are reused to create unity between different moments in the animation. At the same time, transformations of scale, color, and value create contrast, which helps differentiate moments in the animation. Early experimental animation kept time visually with abstract shapes. Pacing is key to Hans Richter’s film, Rhytmus 21 (1921). With the most simple forms Richter was able to explore the transformations of shapes over time through size. Everything is understood through an even, consistent pace, which leads to a contemplation of the purity of form.
In the 1970s, Lillian Schwartz made cutting edge experimental computer animations at Bell Labs. Her work may look like the earlier Richter animation, but the video was programmed using a computer. Her process was similar to our exercises. In her 1971 animation UFO’s the introduction of the computer results in faster edits and elemental shapes. The psychedelic aesthetics fit the topic.
Exercise 1: Understanding After Effects Interface and Creating Solid Shapes
2. Select “New Composition.” Name the Composition “ElementsofMotion.” Make sure the width is set to 1920 px and the height is set to 1080 px. The frame rate should be set to 29.97. For the Duration, set it to 1 second which is 0;00;01;00. Press OK.
4. With the Ellipse Tool, create a circle on the left side of the composition by clicking and dragging while holding SHFT, to keep the circle uniform, and CMD,to keep the circle centered. Name this circle, “Left Circle.”
Exercise 2: Scale, Effects and Keyframes
1. Click on the pull-down menu next to Transform in the bottom left panel.
2. Click and drag, to the left and right, on the blue number value next to “Anchor Point” to move the anchor point to the right of the circle. Alternatively, you can use the Anchor Point Tool (Y) to move the anchor point.
3. Make sure you are in the first frame in the Timeline. The blue slider should be all the way to the left. If not, click and drag the slider to the left.
7. To preview the composition, press SPACE. Keep in mind that the slider will stop at the frame where you pause the preview.
9. Click on the pull-down menu for “Right Circle” and click the pull-down menu for “Transform.” Change the value of the Rotation to 0x+180.0, which will rotate the circle to the right side of the composition. You can either type in the value or click and drag from the blue value.
10. Press SPACE to preview. You should now have two circles that increase in size.
Exercise 3: Opacity
3. Do the same for right circle.
4. Press SPACE to preview. You should have two circles that grow in size and fade out.
