After Effects Script - loop through selected items
by Stephen Kennedy on Jan 21, 2012 at 9:15:26 am

Hi,

I've just started trying to write my first script for AE. Have managed to cobble together a script that executes fine for a single selected item, but I can't seem to find a way to build a for loop to execute the script for every selected item. The script simply takes the item (which will be an image sequence), places it in a new 1920x1080 comp, adds a Transform effect and rescales to 150%. Can anyone help me build a loop for this?
Here is the code:

var mySelection = app.project.activeItem

var myComp = app.project.items.addComp(mySelection.name, 1920, 1080, 1, mySelection.duration, 24)

var myLayer = myComp.layers.add(mySelection)

var myTransform = myLayer.Effects.addProperty("Transform")

myTransform.property(4).setValue(150)

This should work:



var mySelectedItems = [];

for (var i = 1; i <= app.project.numItems; i++){

  if (app.project.item(i).selected)

    mySelectedItems[mySelectedItems.length] = app.project.item(i);

}

for (var i = 0; i < mySelectedItems.length; i++){

  var mySelection = mySelectedItems[i];

  var myComp = app.project.items.addComp(mySelection.name, 1920, 1080, 1, mySelection.duration, 24);

  var myLayer = myComp.layers.add(mySelection);

  var myTransform = myLayer.Effects.addProperty("Transform");

  myTransform.property(4).setValue(150);

}
