  Controling time between keyframes

  Posted by Nihad Spahic on March 17, 2022 at 3:28 pm

  Hello everyone, I wonder if it’s possible to control the time between keyframes or to achieve the same effects without keyframes.

  I have a camera and I am trying to control the x position, the situation is, I have two keyframes, and the expression is connected to sliders where I control the first and the second value of keyframes. Is it possible to control the time between keyframes with slider?

  This is expression:

  var a = thisComp.layer(“Camera Settings”).effect(“Camera In Animation X”)(1);

  var b = thisComp.layer(“Camera Settings”).effect(“Camera Out Animation X”)(1);

  if (numKeys > 1){

  t1 = key(1).time;

  t2 = key(2).time;

  v1 = [a];

  v2 = [b];

  ease(time, t1, t2, v1, v2);

  } else {

  value

  }

  I guess you wouldn’t really need the keyframes if they aren’t providing timing or value info, so this should work:

  x1 = thisComp.layer("Camera Settings").effect("Camera In Animation X")(1);
  x2 = thisComp.layer("Camera Settings").effect("Camera Out Animation X")(1);
  t1 = thisComp.layer("Camera Settings").effect("Camera In Animation Time")(1);
  t2 = thisComp.layer("Camera Settings").effect("Camera Out Animation Time")(1);
  ease(time, t1, t2, x1, x2);

  Thanks Dan! This is exactly what I need.
