Step 1: Create a New Composition
Set up a composition for your animated background.

Set the resolution, frame rate, and duration according to your project.

Step 2: Add a Gradient Layer
Create a gradient background to serve as the base.

Go to Layer > New > Solid and choose a base color.
Apply the Gradient Ramp effect from the Effects & Presets Panel.
Adjust the start and end colors for a smooth gradient.

Step 3: Add Shape Layers
Introduce shapes like circles, rectangles, or polygons for additional design elements.

Go to Layer > New > Shape Layer.
Use the Shape Tool to create the desired shapes.

Step 4: Animate the Shapes
Add motion to the shapes for a dynamic background.

Open the Transform properties of the shape layer.
Animate properties like Position, Scale, Rotation, and Opacity using keyframes.

Step 5: Add Wave or Ripple Effects
Create flowing movement with wave effects.

Apply the Wave Warp effect to the gradient or shape layers.
Adjust settings like Wave Height, Width, and Speed for subtle or dramatic movement.

Step 6: Use Repeater for Patterns
Duplicate shapes to create patterns.

Add the Repeater modifier to the shape layer.
Adjust the Copies, Offset, and Transform settings for evenly spaced designs.

Step 7: Add Motion Blur
Enhance the background’s realism with motion blur.

Activate the Motion Blur Switch for the animated layers.

Step 8: Use Blending Modes and Opacity
Blend layers for a cohesive look.

Experiment with blending modes like Overlay, Multiply, or Screen.
Adjust layer opacity to soften the appearance.

Step 9: Export Your Animated Background
Render the background for use in your projects.

Go to File > Export > Add to Render Queue.
Export in a format like MP4 or MOV.

Conclusion
Animated backgrounds in Adobe After Effects elevate the visual appeal of your videos. By combining gradients, shapes, and motion effects, you can create engaging designs that enhance your projects’ overall aesthetic.
