Control Expressions with Sliders in AE | - YouTubeĪCtually my example is overly complicated. The example is slightly different as it is using a wiggle expression on the position rather than a time multiplier on rotation but hopefully in combination with my above explanation you should be able to work out to get it done. So now here is video going over the general principle. When the slider value reaches 0, 13 will be mu tiplied by zero resulting in a rotation speed of zero. This will multiply 13 * 1 resulting in a rotation speed of 13, Now you key frame the sliders value down from 1 to 0 which will gradually slow the rotation down. Now your expression should look like this (time*13)*thisComp.layer("Black Solid 1").effect("Slider Control")("Slider") Then edit your expression to (time*13)* Place the cursor right after the final multiplication symbol use the expression pickwhip to connect to the slider value. Then you create a null or solid and apply the Effect>Expression Controls>Slider Control. I am just using 13 for the sake of an example. So you would create an expression on the Y rotation something like time*13 You can play with the value to get the rotation speed you want. You could rotate the characters via time expressions and then connect the multiplier to a slider control which you animate one to zero.
