  Offset effect then stop

  Posted by Martin Jean-sébastien on December 11, 2020 at 6:06 pm

  Hello,

  Im using the offset effect to animate multiple background compositions, at different speed. It loops ok but I need to stop the offset smoothly at the end of the animation. And I dont know how to do that!

  My expression is :

  speed=thisComp.layer(“control”).effect(“speed”)(1);

  [value[0]+(time*speed),value[1]];

  The problem is when I create 2 keyframes on the speed slider, from 100 to 0, my “value[0]” return to 0, and it creates an awful animation!

  Sorry for my English, i am a french motion designer!

  Thank you in advance
