  trim paths velocity

  Posted by Peter Zeet on January 12, 2017 at 12:26 am

  Hi!
  I’m trying to achieve this kind of trim lenght via expressions.

  

  I’d usually link the start trim to a slider like this:
  sl=effect("Slider Control")("Slider");
content("Group 1").content("Trim Paths 1").end-sl
  and then animate the slider according to my needs manually, but I was wondering if there is a way to make it work via expressions? I guess it should be something related to the end trim’s velocity and make the slider value go from 0 to lets say 1 depending on the max amount of the keyframe velocity?

  assuming you animated the offset, applying this to the ‘end’ property should start to get you there:

  content("Trim Paths 1").offset.speed * thisComp.frameDuration
