Introduction

This is the result we will create, a spreading circular line explosion above a night lights display, made from just one shape duplicated by the repeater. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. The repeater duplicates the contents of a shape group multiple times, each with increasing transformations. With the repeater, we can create line patterns, concentric circles, and radial explosions from just one shape.

Step 1: One Line

Create a composition from the night lights footage. Press F2, select the rectangle tool, then create a thin orange rectangle 140 pixels long above the center of the screen. Center the layer's anchor point in the middle of the composition.

Step 2: Adding Repeater

Click add in the content row, always select repeater. By default, the repeater creates three sequential copies, because the repeater's transform position is set to 100. Copies determine the number of duplicates. Open the transform repeater 1.

Step 3: Radial Pattern

Change position to 0 and rotation to 3,0 degrees. Each copy now rotates 30 degrees from the previous one, surrounding the group's anchor point. Increase copies to 12, so 12 lines form a perfect circle.

Step 4: Nested Opacity

In the transform repeater, there is start opacity and end opacity. Fill end opacity with 30%. The first copy is dense and the last copy is more transparent, creating a dynamic gradient along the circle. Animate the scale layer from 30% at second 0 to 120 at second 1, then animate the opacity layer from 100 to 0 between seconds 0.7 and 1.2.

Step 5: Explosion Animation

Press F9 on the scale keyframe. The lines spread out and fade away like a fireworks explosion. Add a layer rotation from 0 to 45 degrees so the explosion slightly spins.

Step 6: Rotation and Preview

Change the layer mode to edge so the lines glow and blend with the lights. Rotate the preview.

Done!

Done. We've created one line, added a repeater, adjusted the copies and transform repeater for a radial pattern, created a gradient opacity, and animated the burst with scale, opacity, and rotation. In the next episode, we'll learn about wiggle pads and zigzag. Need a promotional video, logo animation, motion graphics for social media, or visual effects for short films?
