Create AI Visual Backgrounds in After Effects
Learn how to create AI visual backgrounds in After Effects to add dynamic overlay effects and atmospheric motion to your visuals — no plugins required.
In this tutorial, I show you how to generate an AI image and transform it into an animated background using glow, particles, and subtle motion effects. These simple techniques help turn static images into immersive visuals that feel energetic, modern, and cinematic.
This technique is perfect for visualizers, motion graphics backgrounds, social media edits, music visuals, cinematic content, YouTube videos, and creative digital projects that need engaging animated visuals.
Expression (used in video):
freq = 0.25; // flashes every 4 seconds
amp = 1.2;
base = 0.3;
flash = Math.pow(Math.sin(time*Math.PI*freq),20);
base + flash * amp
Create reality 🚀💫
