  Script for scale animation with custom interpolation.

  Posted by Smet Kira on August 24, 2022 at 1:23 pm

  Hi all. I’m trying to make a script so that when I press a button, 2 keys with such interpolation are created on the Scale parameter of the selected layer. I have such code, but I stumbled on setTemporalEaseAtKey. Help me please. Where am I wrong?

   

  var myScaleProperty = app.project.activeItem.selectedLayers[0].property(“Scale”);

  var tStartIn = 0;

  var tStartOut = 1;

  myScaleProperty.setValuesAtTimes([tStartIn,tStartOut],[[0,0],[100,100]]);

  myScaleProperty.setTemporalEaseAtKey(1, [0.5]);

  myScaleProperty.setTemporalEaseAtKey(2, [0.8]);

  Maybe something like this:

  var myScaleProperty = app.project.activeItem.selectedLayers[0].property(“Scale”);
  var tStartIn = 0;
  var tStartOut = 1;
  myScaleProperty.setValuesAtTimes([tStartIn, tStartOut], [[0, 0], [100, 100]]);
  var ease1 = new KeyframeEase(0, 50);
  var ease2 = new KeyframeEase(0, 80);
  myScaleProperty.setTemporalEaseAtKey(1, [ease1]);
  myScaleProperty.setTemporalEaseAtKey(2, [ease2]);

  thanks for the answer! Keys are generated, but they are still linearly interpolated. and same error:

  Sorry, forgot that scale is a 3D property. Try this

  var myScaleProperty = app.project.activeItem.selectedLayers[0].property("Scale");
  var tStartIn = 0;
  var tStartOut = 1;
  myScaleProperty.setValuesAtTimes([tStartIn, tStartOut], [[0, 0], [100, 100]]);
  var ease1 = new KeyframeEase(0, 50);
  var ease2 = new KeyframeEase(0, 80);
  myScaleProperty.setTemporalEaseAtKey(1, [ease1, ease1, ease1]);
  myScaleProperty.setTemporalEaseAtKey(2, [ease2, ease2, ease2]);
