Now, I want to shift gears a little bit and talk about a different type of interpolation. We talked about spatial interpolation, in other words, where an object physically is, interpolating that. And now we're talk about temporal interpolation, interpolation in time. This concept is both harder to understand and harder to get After Effects to do. But the payoff is typically much greater. We have here our arrows again and we have this top arrow and it just goes from point A to point B. I am not going to render that. That's just boring. It goes across the screen.
And then I have this other arrow, the bottom arrow. And if I select these layers and press U to see their keyframes, we will see that they both only have two keyframes. And they both start at the same place at the same time. They both end at the same place at the same time. What's different is the speed in which they get there. And you'll notice the difference here once this renders and plays back. Actually, let me go ahead and just deselect these layers and do a RAM preview so we could see the difference in speed of what's going on here.
So, we have one on top that's been animating or animates in the same way that we have been animating in a very linear, simple way. It just goes from point A to point B at a constant rate of speed. And this one, it takes a while to rev up, goes very quickly, and then slowly decrescendos. It slowly slows down until it gets to its resting spot. And you could see which one has more life, which one has more personality. Obviously the one on the bottom. The one on the bottom tells a story.
The one on the top is very utilitarian. It just gets from point A to point B. But this one, there is movement. There is life to it. And so, what we are going to talk about for this movie and in a couple to follow is this temporal interpolation, basically interpolation in time. So, we know that it starts at one point and ends at one point, but how does it get there? That's what we going to talk about.
