Spiral Background Animation in After Effects

Step-by-Step Guide to Creating a Spiral Background Animation:

Step 1: Setting Up the Composition

• Open Adobe After Effects and create a new composition named “Spiral Background Animation.”
• Use the same resolutions, set 30 frames per second, and a duration of 10 seconds.

Step 2: Creating the Background

1. Right-click on a space, choose “New,” and select “Solid.” Rename the solid layer to “Background.”
2. In the Effects and Presets panel, apply the Gradient Ramp effect to the background. Adjust start and end colors to your preference.

Step 3: Adding the Spiral Element

1. Right-click again, choose “New,” and select “Solid.” Name it “Spiral” and change the color to white.
2. Apply the Venetian Blinds effect. Set transition completion to 50%, and width to 148.
3. Apply the Polar Coordinates effect. Change the type to Rect to Polar and set interpolation to 100%.

Step 4: Scaling and Rotating the Spiral

1. Select the Spiral layer and press ‘S’ to open the scale properties. Change the scale from 100% to 250%.
2. Keep the Spiral layer selected, and press ‘R’ to open rotation properties. Hold ‘Alt’ and click the stopwatch icon, and add the expression “time * 15.”

Step 5: Adjustments and Preview

1. Preview the animation. Adjust opacity or decrease the spiral width by changing the transition completion value.
2. Optionally, reduce opacity or customize spiral width to your liking.

Step 6: Adding Twirl Effect

1. Duplicate the composition by selecting it in the projects section and pressing ‘Ctrl + D.’
2. Double-click on the duplicated composition, and disable the Gradient Ramp effect on the background layer.
3. Apply the Twirl effect to the Spiral layer in the Effects and Presets panel.
4. Set the angle to -90 degrees and the twirl radius to 26.
