Transcription: Now we're just about ready to make a movie, and we're not actually going to create the entire Civil War movie, but just the portion where the soldier is writing in his journal. And we can control the duration or the portion of the movie that gets made using a slider across the top of the construction window. Right now you'll see in the upper left-hand corner of the construction window what looks like a little yellow line with an arrow on the side. Now if we double-click on that, that will extend the duration all the way across the construction window.
