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

|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.|
