The expression I used is: timeoffset = thisComp.layer("top card").effect("Slider Control")("Slider"); thisComp.layer("top card").transform.rotation.valueAtTime(time - ((index - 1) * timeoffset)). Work with Motion Graphics templates in After Effects Use expressions to create drop-down lists in Motion Graphics templates Work with Master Properties to create Motion Graphics templates Last week, we posted a short tutorial on using expressions to measure the distance between two points.This was triggered by playing around with the new Face Tracker in After Effects CC 2015, which in Detailed Features mode generated a number of point controls that track different facial features including the eyes, corners of the mouth, and so on.

Adobe After Effects Expressions. can be applied to: 1D properties. Plus you can add expression controllers to control the speed. Probably not. The easiest thing to do is set one keyframe for rotation at 0 seconds then a second keyframe at 4 seconds. One thing I can’t understand is why the rotation duration is .25 and not .75? Hi there, i’m hoping someone can help me with this, i’m thinking a simple expression should work it out. When an object bounces, it loses energy on each bounce, which affects both the amplitude and the frequency.
