In this tutorial we will create a particle system for emitting specific particles based on a surface type. For example, when the emitter is on the ground we see dirt chunks and when it touches the water we see water splashes. This technique is easy to setup and can be used for motion graphics situations that require dynamic particles types that would be difficult to hand-animate.

The project files contains the expressions and some sample footage to start understanding the concept. For high-resolution footage elements, please check out Action Essentials 2 from our products page!

Side Note: If you use multiple elements from Action Essentials 2, you can create more random effects, like this.

Here is a test video that uses pre-keyed elements from our stock footage collection: Action Essentials 2 for machine gun hits. I used 3 random clips with Trapcode Particular’s custom sprite option. Using a particle system allows you do build complex effects without duplicating the clip hundreds of times, while maintaining precise control.

You could potentially duplicate the particle system and make dirt marks or holes underneath the main particles. I’m sure you guys and gals will think of really creative ways of using real footage elements as particles.

In this tutorial inject life into a still image by creating a 3d-looking camera movement and animate the movement of the smoke. We will also add realistic camera jitter and simulate a rack focus with dirt on the lens.

This tutorial was based on this recent test video that everyone seemed interested in so I put together this tutorial with all of my findings. Enjoy!
