Controlling changes between keyframes

From: Premiere Elements 9 Essential Training

Video: Controlling changes between keyframes

When you put clips in motion using the default settings, the motion starts and stops abruptly. The rate of change, the velocity between keyframes, is constant. There is no acceleration or deceleration. That will look better as for the motion to start and stop gradually. Well, you can fix that by using commands called Ease In and Ease Out. In addition, when you put objects in motion along a curved path. You can use something called Bezier curve handles to customize that path. Let me show you here with a few clips on this Timeline. We'll start with a rose. I set the rose up just to go from left to right.

Controlling changes between keyframes

When you put clips in motion using the default settings, the motion starts and stops abruptly. The rate of change, the velocity between keyframes, is constant. There is no acceleration or deceleration. That will look better as for the motion to start and stop gradually. Well, you can fix that by using commands called Ease In and Ease Out. In addition, when you put objects in motion along a curved path. You can use something called Bezier curve handles to customize that path. Let me show you here with a few clips on this Timeline. We'll start with a rose. I set the rose up just to go from left to right.

If I click this, it just kind of starts abruptly and sort of stops abruptly. Now with the resolution that you might be looking at it in your monitor, and also the compression that we use, it might kind of jump around. But basically, it's just kind of boom started, instant acceleration, boom stopped, and instant stop. It's nice to smooth that out. The way you smooth that out is here in keyframes. There is the Position changing. Only one set of keyframes really. The rest of these guys are starting points with no ending points. This is only one we're talking about. That's Position and the Position changes from there to there. I can navigate using these guys from there to there.

What I want to do is I want to make that sort of gradually increase in speed as it moves from left to right, and gradually decrease in speed as it get to this keyframes. It's very simple to do that. Just right-click on the keyframe here and there is something called Temporal Interpolation and Spatial Interpolation. Spatial just in terms of how it moves through space and Temporal is how it moves through time. So time is what we're talking about here. We're talking about acceleration. That's something over time. Click on Temporal Interpolation and it's all these various options. But the easiest ones to use, the ones we'll use for this course, are Ease In and Ease Out.

So we'll Ease Out of this keyframe. You get a little hourglass saying we're going to ease out. So now when you get out of there, it won't suddenly accelerate. It's going to gradually accelerate out. It's much smoother and then it gets rolling and gets up the speed. Then it still kind of, boom, bumps into that next keyframe. Oh, I think you obviously know what the next step is. That's to Ease In. So we right-click on this keyframe, Temporal > Ease In. Now when it goes from left to right, it's a much more gradual process. Again, the view of your monitor and ours might be not smooth, just because of all of various technology issues.

But it's still, in the end, when you actually send this video some placeand share it, it'll be smooth. Gradually goes out, gets up to speed, and gradually slows down. Much nicer way to go. Well not only can you do this with movement; you can do this with scales. Let me go back to the first keyframe. I navigate to it using this little triangle. I'm going to work with Scale now. So I am going to take the Scale down a little bit like that, here we go. I'm going to go to the next keyframe over here. I want to navigate to that keyframe. I'm going to apply Scale at that location. So I'll just navigate to the keyframe by clicking up here.

Now I'm going to just scale this. down here. By adjusting Scale that will automatically add a keyframe there, make the Scale much larger now. So when we go from small to large, what's going to happen is that it's going to instantly start getting larger, instantly stop getting larger. Let's just show how that works. Just suddenly gets running and boom! and it stops getting large. But what I want to do is change that too. I can also change that because that's changing over time. Something changing over time we'll use the Temporal view. So I'm going to right-click. Say Ease Out of that keyframe over here.

Since this is not a motion, it doesn't have that extra little drop-down menu. Right-click and say Ease In. Much nicer motion now. It's going to ease out of that little motion as it grows up and that's going to slowly stop growing. Much more natural. So, you almost always want to use the Ease In and Ease Out to make your transitions a little bit smoother. One more thing. I want to show you the motion path. I am going to click on this and you can see there is the motion path. So with Motion is selected, you can see your motion path that goes from over there to over here. As I go to this keyframe in the left right there, there is that little beginning point right there, and then here is the ending point over here. If I go to that keyframe, it will pop over to that little ending point right there.

I want to add something in the middle. So I'm going to drag this over here like that. I'm going to change the position here inside the Monitor panel by grabbing this little target, dragging up like that. So now the motion path is going to go up and down. I want also to change the endpoints position. So I am going to navigate to them by clicking over to the left first to that one, drag that one down, navigate over to the right one, and drag that one down. So what I want you to notice in particular here is that a motion path that's not just a straight line, by default in Premiere Elements is a Curve, which is a good thing.

That's more natural. Some of products always make these things straight lines, like a triangle, boom, boom. But by default, Premiere Elements create a motion curve when you have something other than a straight line, be it diagonal or just straight across the screen. Notice that when you have this little curve, you have what are called handles on it. I'm going to click on the center keyframe by navigating to it, make that active. When you make it active, it's hard to see, but little handles appear here. When you hover your cursor over it, you get a little zero down there in the lower right-hand corner, little O. See a little O there, below the cursor? The cursor changes to a black triangle when it gets that little O.

That means you can grab the handle and adjust the shape of your curve. You can either move it up or down. If you drag it to the right or the left, you kind of change the shape on the right-hand side here. You are making the sort of a steeper slope as it goes down the right. Or a different kind of slope like that, almost straight there. You can adjust the length. Whichever keyframe you could click on here, handles will be available to the ones next to it. So since it's the center one, there is a handle down here. It's like I adjust the curve down there. Since the center is selected here, there is a handle here as well. So I can adjust the shape of your curve, which is a really cool thing.

So now it's a nice way to fine-tune how Motion works inside your project. So, let me show you what we ended up with here. Gradually leaves that one, gradually grows, and then gradually ends up like that, it follows that curve, which is only natural motion for it. Let me show you how this works when you're working with zoom, let's say, in a photograph. Here is this big photograph we've got. We're going to zoom in on that. So I'm going to pick this photograph. Select it to make it active. No keyframes yet. I am going to set a Position keyframe, so we just click on the keyframes stopwatch. Now everything is set. We'll go little bit into the clip and I want to zoom in now.

So just click on the Motion, and I can pull this in back like this. Ebventually it's going to kind of go off the page. This is one way to zoom, manual one. Even I could drag it like it or I just take the Scale and Scale up. Now I need to click and move it around to find this guy in the porch, there they are. So now, all those little machinations around them, sliding here, sliding left, sliding right, Premiere Elements is not recording that. It's just looking at the ending point. It's like okay, this is where I ended up. Okay. That's where we're going from and to. So we're going to go from this wide view and to this tight view.

Now along the way we change the Scale and we change the Position. Now if I do that just straight without having done any Ease In or Ease Out, it's just going to be abrupt. It's going to go bunk-bunk, which is the not really what we want to do. We want to Ease In and Ease Out. So I'm going to select all of these keyframes by marquee selecting them, three at once now. Then I am going to right-click, go to Temporal, we'll say Ease Out. All right, so you can select all at once, make them all Ease Out. I'm going to select the three that we go into, right-click on those guys, Temporal, and Ease In.

I noticed that there was kind of a short time between the two motions, those starts and stops. So I'm going to grab these three, slide them later into the five-second clip. So it'll take a little longer to get from point A to B, here we go. Now it's going to Ease In. Again, it's because of the process we're working really hard here. I'll just sort of manually show you, but trust me by using these little Ease In and Ease Out guys, when you finally share your clip this will be very smooth. It'll leave the wide shot gradually, and zoom in relatively steadily, and then slowdown as it gets to the end of the zoom.

Let me show you one more thing that you can do. Not only you can use the sort of Ease In an Ease Out approach when talking about motion or having objects change shape and size. You can use them with regular old effects. So I'm going to take the Effects here. I'm going to go find a preset, Fast Blur In let's say. I'll drag this preset down to underwater-wide. So what's going to happen now is we are going to zoom in on that. So it's going to go whirr, and then basically it goes from being blur to being sharp. If I look at the keyframes for that, click on this guy, Edit Effects, you see the keyframes are these two diamonds, which means there is no easing in or easing out.

But you can Ease In and Ease Out even just a visual effect like this. I am going to right-click on this guy and there we go. We can Ease Out of that keyframe and Ease In to this keyframe. When you do the Blur then, the blur will slowly start getting sharper and it'll gradually get sharper, then it kind of down settle down at the end. So you can use this whole Ease In/ Ease Out concept for things other than objects in motion. So when you use effects that you want to gradually start or gradually stop, apply Ease Out or Ease In to them.

When putting clips in motion, you can adjust the motion path using Bezier curve handles.
