After Effects Video Tutorial: Stamp or Icon Impact

Make your motion titles more impactful with this After Effects trick.

Adobe After Effects

One of the hardest things to do as a motion designer is to create realistic physics in Adobe After Effects. In the following video tutorial we will take a look at how to preserve and create realistic inertia in Adobe After Effects. The video covers:

  • Using the merge layers effect on shapes
  • Using inertia scripts
  • Using sliders to dictate expressions.

The inertia script is a great tool for any physics based projects. You can download it from GreyMachine.

Don’t want to watch the video? Follow along with the step-by-step tutorial below. Click any image for larger view. 

1 Create a new composition and add in circular shape. Add a merge paths effect and subtract a star from the circle.

2 Create a new background solid, any color will work. You also probably want to set your shape fill to white.

3 Make everything 3D and create a new null object.

4 Parent both the shape and the background to the 3D null object.

5 Set keyframes for where you want your stamp to end.

6 Set the start position to be off screen.

7 Add a slider control to the null object.

8 Set keyframes of 0 50 and 0 to coincide with the stamp landing on the background.

9 Go to the GrayMachine site and copy their inertia script.

10 Alt-click on the slider keyframe and paste in the script.

11 Add a wiggle expression to the position of the null object, 1 times per second with the second parameter of the null object being parented to the slider control.

12 Add the same wiggle expression to the rotation of the null object and multiply it by .1.

13 Add a noise HLS to the background to simulate texture.
