In After Effects CS5 Essential Training, author Chad Perkins discusses the basic tools, effects, and need-to-know techniques in Adobe After Effects CS5, the professional standard for motion graphics, compositing, and visual effects for video. The course provides an overview of the entire workflow, from import to export, as well as detailed coverage of each stage, including animating text and artwork, adding effects to compositions, working in 3D, and rendering and compressing footage. Exercise files are included with the course.
In the last movie, we saw how to trim footage in the Timeline panel. There are lot of times, such as the last movie, as a matter of fact, where we had a 54 second long clip, and this one we have 19 second long clip. But these clips are just way too long to put in the average After Effects Timeline. In it's entirely, usually you just want one little snippet from that clip. So, what we can do is actually double -click a clip in the project panel. This won't add it to a composition. This will open it up in what we call the Footage panel. You can tell the difference between the Composition panel and the Footage panel by the colors of these swatches here, and also because of the name.
It will say, Composition here, showing us our composition. And this will say Footage, showing us just this footage. Now what we can do is skim this clip. And there is a lot going on here in this clip, if I were to scrub it. There is this initial jump that's really cool, and then it turns into like the equivalent of a skateboarding real slide. And then there is almost like a 720-degree flip here, and let's say that's what we want. So, I am going to back up right before this, and it's good to get a little extra, a little buffer on both sides, just in case you decide to use some of that layer.
I want to click this left little button here. That's going to click and set the In point of this clip, and I'm going to go out until the snowboarder lands the clip right about there. And I'll go ahead an click an Out point for it. And we'll click this button there to do that. And as you could see, that's almost like trimming in the Timeline, where we have cropped this to - this is the In point, and this is the Out point. And again, just like in the Timeline panel, as we saw in the last movie, you can extend this if we want to after the fact. We haven't destroyed anything.
So, it's still there. And then we want to add it to our Timeline. We can click this button here to perform an overlay edit, or click this button here to perform the ripple insert edit. Now let me go back to the Footage panel here and show you those buttons, again, a little bit more closely. The one here on the right is the Overlay button. That's going to replace whatever layer is selected. And if you select this button, the Ripple Insert Edit, what that's going to do is it's going to move a space, or create a space for this clip, and then move everything else to the right. I should also point out that once you have created your In point of your footage that where it actually starts from, any Out point of your footage.
You'll see that here. You'll see the In point, the Out point, and then the clip duration as it stands. Let's see where we take the Out point, and make the Out point longer. You can see that the Out point is extending here, and it's also increasing the duration of the clip. Notice that as I go back to the Footage panel, it's not adjusting what we've already added to the Timeline panel. But now if we go back to the Composition panel, you'll see that, in our composition, we have this clip, and we don't have anything else before it. So, if we go to the beginning of our composition, we'll see the beginning of the snowboarding clip, and the Out point will be when the snowboarder lands, and nothing else from the video.
Now again, we have this faded area here. So, if we wanted to extend it, we could. So, it would match what is in the Project panel. But that is a good way to make sure that you don't have these huge 20-second, 50- second long clips in your Timeline panel trying to trim them here. It's usually best to get what you need in the Footage panel and then bring that to your composition, so you have a small amount to work with. Now, let's see that you do add a really long clip to your Timeline. I'll just go ahead and drag this clip into our Timeline panel here.
So, we're seeing now the shortened clip, and then we're also seeing the full-length clip on top. What I can do is double-click that clip, and it will open in yet another window, which also looks like the Composition panel, and the Footage panel. It's called the Layer panel. And this Layer panel will allow you to preview just this layer without any of the effects you might have applied to it. And then you could go ahead and set an In point, set an Out point, if you wanted to. And you could see that the clip in the Timeline panel changes accordingly. So, it's just kind of like the Footage panel, but for layers that are already in your composition.
And this is why it's good to remember that when you want to rename a layer, you press the Return key, and you don't double-click the layer, which is a tendency for a lot of people. Also, know that once you make edits in the Layer panel, or the Footage panel, you don't need to keep it open. You can click the little X to the right of the name and get back to the Composition panel if you want to. So, just a couple of extra places to trim video.
