  Add keyframe on current Time

  Posted by Sebastian Moreno on June 7, 2016 at 6:58 pm

  Simple but weird. I can’t get to use addKey where the Current time indicator stands. I just want to add a key frame to the shape layer:

  opaCity = shapeLayer.property(“Transform”).property(“Opacity”).setValue(0);

  btn6.onClick = function(){

  shapeLayer.property(“Transform”).property(“Opacity”).addKey(KeyframeTime);

  }

  ////I tried this and other couple of things for this” KeyframeTime”:

  KeyframeTime = app.project.items.testComp.layers.shapeLayer.keyTime(1). — and isnt working

  You need to identify where the timeline indicator is currently positioned in time
  activeComp = app.project.activeItem; // Collect the active composition
keyTime = activeComp.time; // Identify the current position of the timeline indicator

  opaCity = shapeLayer.property("Transform").property("Opacity"); // Identify your opacity parameter
opaCity.addKey(keyTime); // Add keyframe
opaCity.setValueAtTime(keyTime, 50); // Set the keyframe's value to 50

  Ohhh Mike thank you
  I didn’t know about this active syntax and the combination of addKey and setValue.

  Brilliant.
  Thanks again
