  Set a keyframe on every frame between 2 keyframes

  Posted by Isa Dimpfl on January 24, 2023 at 8:16 am

  hi,

  i made a curved animation path which a shape should follow. but when i am exporting it as an svg animation via bodymovin (lottie) the shape moves on a straight line.

  i assume that i can fix this problem by generating keyframes between those two keyframes, so the shape has a specific position on each frame.

  is there an easy solution to set a keyframe on every frame between 2 keyframes?

  thanks in advance!

  You could run a little script like this:

  var comp = app.project.activeItem;
  var layer = comp.selectedLayers[0];
  var props = layer.selectedProperties;
  for (var i = 0; i < props.length; i++){
  	if (props[i].canVaryOverTime && props[i].numKeys >= 2){
  		var t1 = props[i].keyTime(1) + comp.frameDuration;
  		var t2 = props[i].keyTime(2) - comp.frameDuration/2;
  		var t = t1;
  		while (t < t2){
  				props[i].addKey(t);
  				t+= comp.frameDuration;
  		}
  	}
  }

  thank you so much, i will give it a try.

  its surprising that there is not a built-in option in AE which does this for you – i don`t think that this is such an exotic demand..
