Creating Fog with Fractal Noise
COW Library : Adobe After Effects : Andy Ford : Creating Fog with Fractal Noise
Fractal Noise is a loaded effect within After Effects that creates grayscale noise. This effect can be used for numerous things, such as creating patterns and textures, transitions and effects, and displacement maps. I’m talking amazing textures ranging from rocks to wood to fire to water. It can create light wipes or energy waves. The best way to learn more about this effect is to play around with it yourself.
In this 3-minute video tutorial, I will quickly review some key settings within Fractal Noise while we work to simulate some ground fog over a video clip.
We will add the effect to a solid and look at settings such as Fractal Type, Noise Type, Contrast, Brightness, Transform, Complexity, Sub Settings, Evolution, and Offset Turbulence. We will then change the layer to a 3D layer to create depth, add a mask for realistic fog drop-off, and keyframe to follow the movement of the video clip.
This is just one quick example of many on how to use Fractal Noise to create fog.
