Alright, before we move on, what I want to do is just make sure you know how to change the length of your composition. So we've picked 10 seconds, you might get to a point where you want it to be longer or your animation needs to be shorter, its stuck at 10 seconds at the moment, you can kind of see it down here, one, two, three, four, five, six, seven, eight, nine, ten. Yours might have slightly different numbering along here, don’t sweat it, were going to look at that later on.
So to change the length, you click on your comp, right click it and go down to comp settings, in here, you can go through and change the duration, I want it to be 5 seconds now. Click okay and it’s going to be only five seconds long.
Alright, easy, that’s how you change the length of your composition in after effects.
