Rich: One of the advantages of After Effects is time remapping. Now, you might be thinking, didn't we already change the speed of the clip. Absolutely, but After Effects gives you the ability to variably change the speed of the clip. So, maybe you want one speed of time lapse and ramp into another. Here's how. I've got my composition here and I'm just going to extend that by a few seconds. Now, my comp is longer than my clip. What I can do is choose Layer > Time > Enable Time Remapping. And you'll notice that we have different frames here. The frame at the beginning is frame zero.
The frame at the end is frame 123. Remember, we stretched this out 300%, so, that frame got re-timed a bit. If you took 123 times 3, it would be approximately 521. What we're going to do is extend this out. I'll press the Caps Lock key to temporarily disable the preview window, and I'll drag that out to the end. What's going to happen right now is it's going to go from this first frame to the last frame, and then freeze.
Well, maybe you don't want that. How about we drag this out a bit and then come into the middle here, and assign a higher frame value. So, essentially, I just told it to go from zero to one a lot faster, and then gradually get around to 123. The clip is going to play back at two different speeds. What we'll do here is tell it to Ease In to that and come to a gradual stop. We'll tell this to Ease Out.
And for the middle one here, I could tell this to have Easy Ease. If you look at the velocity graph there, you see what's happening. And you can adjust these handles to get a smooth animation. Let's drop this down to quarter quality, and we'll do a preview. Now, the ran preview with the Raw file is going to take longer, but what you're going to see is a variable speed effect. The time remapping effect gives you a lot of flexibility of controlling how it moves from one part of the shot to the next.
I like to use this effect to go ahead and get some interesting moves, on a particular shot. Sometimes I like the action to freeze or actually come to a complete stop. This is a fun way to really take control over the shot. So, here it is on the example we just did. You'll notice that the shots are moving very quickly, and then it slows down to a more staggered movement. So, fast to slow. You can use timer mapping as a great creative control, including the ability to essentially freeze action in the shot itself.
