Welcome to episode 8 of the After Effects ExtendScript Training series. Using a lot of what we've already learned, we are going to combine some of the past code and make a decent sized script to create multiple comps of different sizes. We will also use Undo groups to package our code into one easy undo action. We'll start to use the writeln() method as well to give us unobtrusive feedback and we'll use a try catch statement to help us catch scripting syntax errors. In the second half of the video we will modify our script to create a solid layer of a specific color and place it into all of our comps. We will also make the solid match each of the custom comp settings.
