In this video tutorial, you will learn how to create atmospheric smoke effects in Adobe After Effects without using any external plugins or stock footage. This effect will add dynamic elements to the background of your motion graphics.

Start by creating a new full HD composition and a solid layer. Search for "Fractal Noise" presets from the effects and presets panel. You can create different variations by adjusting the speed and size of the fractal noise.

In this tutorial, we will be using the "Noise" and "Fractal Noise" effects. Apply your chosen fractal noise effect to the solid layer. Experiment with the contrast to manipulate the intensity of your smoke. Additionally, you can scale your clouds to make them wider or narrower.
