  Animate from zero to slider value

  Posted by Rob Jennings on July 1, 2019 at 7:45 pm

  Hi everyone,

  Is is possible to add a layer expression to keyframe from a given value to another value dictated by a slider control over time t?

  For example, I would like to create a radial wipe using an expression that starts at 0% completion (value 1) at time 1, then animates to an endpoint controlled by a slider (value 2) at time 2. Is there any such expression?

  Thanks!

  linear(time,t1,t2,value1,value2)

  t1 – initial time
  t2 – final time
  value1 – initial value
  value2 – final value

  Instead of writing value2 you should pick-whip your slider.
