Chapter 19 - Pacing

Rhythm is an essential consideration in the production of motion graphics. One of the most common and simple time signatures is 4/4, where four beats are evenly heard over one bar of music and each note is one beat. House Music has a 4/4 beat. This method of counting time can be applied to animation. In House music, the beat is counted in cycles of eight. The rhythm is established and peaks at the fourth beat. It reduces in the next four beats, in preparation for the next set of eight beats. One of the key concepts in understanding animation is visualizing time. Whether you are keeping track of the musical score or graphic frames on a timeline, counting time is important and "seeing" the count is a necessity.

Early experimental animation can be drawn upon as an example of seeing time kept with abstract, basic shapes. The work we will be doing is more like Oscar Fischinger's later work, "Early Abstractions" (1946 - 57). Harry Smith's homage to Fischinger remains abstract, though it is even more layered and complicated. Balance changes over time, shapes change in size and transparency. Rhythm is used to create a sense of predictability within the abstraction.

Exercise 1: Adding Sound Clip and Define Length of Clip

1. Open Adobe After Effects. Select “New Project…” in the startup menu.

Fig19 Ex1 01 CC2018.png


2. Select “New Composition.” Name the Composition “Pacing.” Make sure the width is set to 1920 px and the height is set to 1080 px. Set the frame rate by selecting 29.97 from the pull-down menu. Set the Duration to 2.12 seconds which is 0;00;02;12. This is because we will be using an audio file that is 2.12 seconds long. Press OK.

Fig19 Ex1 02 CC2018.png


3. Import the sound clip and AI file using File > Import > Multiple Files…

Fig19 Ex1 03 CC2018.png


4. Drag the sound clip from the Project Panel to the Layers panel to insert it to the composition.

Fig19 Ex1 04 CC2018.png

Exercise 2: Placing AI File, Draw Out Solid, Add Letter “O”

1. Move the AI File to the composition by dragging it to the layers. Move the Circle to the bottom left of the composition.

Fig19 Ex2 01 CC2018.png


2. Draw a Solid Circle using the Ellipse Tool and move it to the right side of the composition, centered vertically. You can change the fill and stroke from the toolbar.

Fig19 Ex2 02 CC2018.png


3. Select the Type Tool and add the letter “O.” Move it to the center of the composition and make sure its anchor point is in the center using the Anchor Point Tool (Y). Adjust the circles so that all three are roughly the same size.

Fig19 Ex2 03 CC2018.png

Exercise 3: Changing Position of AI File, Change Hue of Solid

1. Create an initial keyframe so that you can change the position of the circle. In the layers panel, click the arrow next to the “Circle.ai” layer to expand the twirl down menu. Do the same for the Transform menu, and then click the stop-watch next to Position while the playhead is at the first frame.

Fig19 Ex3 01 CC2018.png


2. Move the playhead halfway through the composition so that it is exactly at 1:06 seconds. You can find the time at the bottom of the composition panel. Change the position of the circle so that it is higher than its previous position.

Fig19 Ex3 02 CC2018.png


3. Move the playhead to the last frame. Click on the first Keyframe we made in step 1, copy it, and paste it to the last frame.

Fig19 Ex3 03 CC2018.png


4. Press SPACE to preview.

5. Select the solid shape and make a keyframe for Color (Contents > Ellipse 1 > Fill 1) at the first frame.

Fig19 Ex3 05 CC2018.png


6. Move the playhead halfway (1:06) and change the Color.

Fig19 Ex3 06 CC2018.png


7. Go to the last frame and duplicate the first keyframe.

Fig19 Ex3 07 CC2018.png


8. Press SPACE to preview.

Exercise 4: Change Opacity and Scale of “O”

1. For the “O”, make a keyframe for scale and opacity at the first frame.

Fig19 Ex4 01 CC2018.png


2. Move the playhead halfway so that it is at 1:06 seconds. Change the scale so it is larger but not touching the other circles. Then change the Opacity to 0%.

Fig19 Ex4 02 CC2018.png


3. Go to the last frame and copy the key frames from the first frame to the last frame.

Fig19 Ex4 03 CC2018.png


4. Press SPACE to preview.

Exercise 5: Exporting and Rendering

1. Save the composition by selecting File > Save As > Save As… and name the project “Pacing.”

Fig19 Ex5 01 CC2018.png


2. Then Export by selecting File > Export > Add to Render Queue.

Fig19 Ex5 02 CC2018.png


3. Change the value of “Output To:” by selecting the blue value and choosing where the composition will be exported to. Click save.

Fig19 Ex5 03 CC2018.png


4. Click on Render on the right. This will export and render the video to an MOV file.

Fig19 Ex5 04 CC2018.png

Exercise 6: Looping

1. Make a new project by selecting Composition > New Composition or by using the shortcut, CMD + N.

Fig19 Ex6 01 CC2018.png


2. In the Composition Settings Window, name the new composition “PacingLoop” and make the duration 10 seconds (0:00:10:00). Click OK

Fig19 Ex6 02 CC2018.png


3. Select File > Import > File… and select the Pacing.mov file that we created earlier.

Fig19 Ex6 03 CC2018.png


4. Click and drag Pacing.mov to the layers panel and press SPACE to preview. As you can see, the Pacing file only lasts for 2 seconds of our 10 seconds.

5. Right click the Pacing.mov layer and select Time > Enable Time Remapping. This will create a property with a keyframe under the layer.

Fig19 Ex6 05 CC2018.png


6. Option + Click the keyframe icon to create an expression. Expressions are bits of code that tell After Effects details about the property, in this case Time Remap.

Fig19 Ex6 06 CC2018.png


7. Click on the Expression Language Menu, which is the circle with the triangle within the expression layer.

Fig19 Ex6 07 CC2018.png


8. From the Expression Language Menu. Select Property > loopOut(type = “cycle”, numKeyframes = 0)

Fig19 Ex6 08 CC2018.png


9. Now drag the end of the Pacing.mov layer to the end of the composition. This will tell After Effects to loop until the end of the composition.

Fig19 Ex6 09 CC2018.png


10. Press SPACE to make check that Pacing.mov is looping for the 10 seconds. If it is, continue exporting and rendering the composition like in Exercise 5.
