Showing off vacation highlights or making a music video with a professional touch is just a few keystrokes away with Premiere Elements 7. In Premiere Elements 7 Essential Training, Jeff Sengstack, Adobe Certified Expert in Premiere Pro, breaks down the editing workflow into bite–sized pieces, about everything from setting up a project to exporting the final video to any format. In between, Jeff covers the basics of editing as well as advanced features like picture–in–picture overlays and dazzling visual effects. Exercise files accompany the course.
In this tutorial, I want to give you a basic demonstration of how keyframes work. How you can animate effects over time using something called keyframes. If you want to follow along, open up 08 -overview. What I have here are three clips on the Timeline, two of them have effects applied with keyframes and one does not. I'm going to show you the whole process of applying an effect and then adding keyframes just to give you a sense for how it all works. So to do that, I select this clip and go to Edit, click on Effects and I'm going to add, let's say, the Pastel Sketch effect. I can do that by dragging it to the Monitor, dragging it to the clip or clicking Apply. So I'll just click Apply. That's what Pastel Sketch looks like when you have applied it to the clip, and if I play it, it looks like it's animated.
That's because the video is moving and has action in it, but in fact, nothing is changing in Pastel Sketch. None of the parameters are changing over time but you can make those parameters change over time using something called keyframes. So to see that in action, click on that, click on Edit Effects and there is Pastel Sketch. If I open it up, there are two parameters and that's the default setting. If you want to change the default setting you can change to that to suit your purposes. But then that won't change over time either. That will just be static. If you want those parameters to change over time, you need to do what are called keyframes. I'm going to start the clip at the beginning, we're at the beginning, and click this little stopwatch to say apply keyframes. When you do that, these little guys pop on the screen. Every parameter can be animated; every parameter can have keyframes applied to it.
To see the keyframes, I open up this little Show Keyframes view, this Timeline view. I'm going to say, I want this thing to start looking normal. So I've told Premiere Elements that this keyframe right there indicates the start of this change, and the start is that it looks normal. Now if I go into the clip a little ways, couple of seconds, there are no keyframes here yet, but when I change this keyframe, it will look like that. I'm going to change the Density like that. Now as I said, when you go from here to there, I want you to make this change gradually over time from that location in the clip to this location. Let's see how that works.
There you go. This keyframe marks the start of a change; this keyframe marks the end of that change. But in fact, this keyframe can also mark the beginning of the next change. If I want to go from there and go back to normal, for example, I have now said, okay you went from normal to fully applied effect, back to normal, let's just see how that works. Starts normal, goes into the effect, and then goes back to normal. So you could have effects change over time using keyframes. The keyframes mark the beginning and end of the change, and the change happens linearly, it's called interpolation as it goes form point A to point B.
You can actually make the effects start faster or start slower or end faster end slower, and that's something we'll talk about in another tutorial, doesn't have to be a linear change. Let me go to this next thing where we have an effect applied to a title. Now, here I applied two effects, and you can have those effects behave independently which all are using keyframes. So Alpha Glow, for example, causes this thing to glow like that. This effect down below, the Pastel Sketch as you've seen before, it causes it to kind of look like something is being written on it. I have each of those things behaving independently of each other. You can have the timing and that would be completely different from one effect to the next.
Let's see how that works. Starts to those points, changes to that and then changes back to something else. Each keyframe marks the beginning and end of a change. Finally, you can have keyframes follow motion. This particular clip, as you noticed earlier when I explained this in another tutorial, the effect can follow action. If you look over here, you see lots and lots of keyframes. What I did was I went along and followed the motion of the ray's eye, and have the Flare Center move with the ray. Now watch the numbers there, 156.3 and 267.3, as I move along, those numbers are going to change as the location changes. Those numbers indicate a location on the screen by coordinates. To do that, you just follow the action and then keep on adding keyframes as the action moves and to drag the Lens Flare to the center.
So what I tried to show you here is that you can use these things called keyframes to mark the beginning and end of a transition in an effect. That way an effect can be animated over time and you can apply many, many keyframes and have that effect change independently of other effects and even follow action like this. I'm going to explain all this in some other tutorials and show you the hands-on way to do this later.
