  Accesing 1st and 2nd keyframe of a mask from selected layer

  Posted by Tom Pinnes on December 31, 2020 at 7:01 am

  Hello everyone i just started scripting with ExtendScript ToolKit and i’m in need of some direction.

  I’m trying to write a script that collects the vertices of a mask from the 1st keyframe and 2nd keyframe.

  *Assume the layer is selected and a layer holds at least 2 keyframes and is a rectangle.

  Here is my code so far, it’s lacking the most important part and this is where i need your help 🙂

  var project = app.project

  var currentComp = project.activeItem

  var selectedLayers = currentComp.selectedLayers

  var myLayer = selectedLayers[0]

  var layerIn = myLayer.inPoint

  var layerOut = myLayer.outPoint

  var selectedMask = myLayer.Masks(“Mask”)

  var newMaskShape = selectedMask.property(“maskShape”)

  var newShape = newMaskShape.value

  var shapeVert = newShape.vertices

  /// Find a way to select 2nd keyframe vertices

  Thanks in advance !

  I think what you want instead of newMaskShape.value is newMaskShape.keyValue(1) and newMaskShape.keyValue(2). Also, don’t forget the semi colons at the end of your statements.
