Learn about expressions, keyframe animation, effects, and more in this detailed After Effects tutorial!
We’ll create a looping, bursting particle effect that animates along a path and reveals a sliding text logo in our video composition.

Tutorial Recording Notes:
Disclaimer: these are the actual notes I used to record this video and are written in a language you may or may not understand. Hopefully, you find them useful or cool.
- New composition at UHD size 3840×2160 w/ black background
- Type out the word “Particles” using Kenyan Coffee at 385pt with 225 tracking and set to all caps
- Align the text to the center and line up the anchor with the center as well
- Create a new Null object (make sure you select it in the Layer’s panel) and use the Pen tool to draw the path along which you want the particle burst to occur
- Hit the letter “M” and copy this mask path we just drew and then delete it
- Hit the letter “P” to pop open the position, select it in the layer’s panel and paste that path in here to create our animation-along-a-path
- Create a new Solid layer and drag out CC Particle World and shut off all the guides for it
- Set Velocity and Gravity to 0
- Set the shape to Tetrahedron with a birth size of 0.010 and death of 0.250
- Set the birth color to #00DBCB and death color to #5D00F1
- Size variation to 100% and opacity both at 50%
- Under Physics, set Animation to Viscouse and 0.50 velocity
- Birth rate 55 and Longevity 0.6
- Now we want to link the movement of the particle production to that Null object animation we just made
- Alt/Opt click the stopwatch for Position X and write this expression to link this to the movement of the Null object:
- (thisComp.layer(“Null Layer Name”).position[0]-(thisComp.width/2))/thisComp.width
- Alt/Opt click the stopwatch for Position Y and write this expression:
- (thisComp.layer(“Null Layer Name”).position[1]-(thisComp.height/2))/thisComp.width
- Select the Null object layer and adjust the speed of the animation to speed this thing up
- Animate a tracking bounce, linear wipe, and a 3D Y rotation to this text and work it in with the particle trails
- Add a gradient ramp to the text layer to blend the bottom of the text into the background
- Drag video in for the background, scale up using Cmd + Opt + F and then drag blue wash effect onto that video layer and reduce the overall opacity to 10%
- If the bottom of the text is visible, set the text layer to Screen to drop away the black
- BOOM!
