  replace source – How to replace layer with a comp – Scripting

  Posted by Inna Bunmi on January 2, 2013 at 7:33 am

  Hi,

  I edit a video in Adobe Premiere using several clips. I import the project in After Effects as a composition with several layers edited accordingly.

  I am trying to write a script that will do the following:
  – Create Comps for every piece of footage in the project window.
  – Replace the instances of the footage in the edited composition with the Comped versions of the footage.
  So basically if I open a footage comp and add color correction it affects all instances of the footage in the edited composition.

  Here is what I have so far:

  { var mySelection = app.project.selection;
  // Identify the Sequnce in which the footage will be replaced

  for (var i = 1; i <= app.project.numItems; i++){
  //var myComp = app.project.item(‘Sequence 01’);
  if (app.project.item(i).name == “Sequence 01”){
  var myComp = app.project.item(i);
  }
  }

  for (var i = 0; i < mySelection.length; i++){
  var aStr = mySelection[i].name;
  var aWidth = mySelection[i].width;
  var aHeight = mySelection[i].height;
  var aPX = mySelection[i].pixelAspect;
  var aDur = mySelection[i].duration;
  var aFrm = mySelection[i].frameRate;
  var movComp = app.project.items.addComp(aStr + “_Comp”, aWidth, aHeight, aPX, aDur, aFrm);
  movComp.layers.add(mySelection[i]);

  for (var j = 1; j <= app.project.numItems; j++){
  if (app.project.item(j).name == aStr + “_Comp”){
  var currentComp = app.project.item(j);
  }
  }
  //movComp.layers.addText(mySelection[i].name);
  myComp.layer(mySelection[i]).replaceSource(app.project.item(1));
  }
  }

  I get stuck on the replace Source bit.

  Help is greatly appreciated.

  Thank You
