Transcription: Animation, Part 1

Hi, welcome back to educator.com. 0000

This next lesson is on animation, part one. Basic transformation. 0003

In After Effects we are really just creating the illusion of scaling in, scaling out.0010

Like when you see a scene in a movie where you are zooming in or zooming out. 0017

In After Effects we are not using a 3D camera. You have to do that with scaling.0021

And it is a real basic simple technique. 0028

So, for instance, let us take this clip here of our Six gun Sally character.0031

And let us just do a quick RAM preview of her shooting her gun here.0038

So, I am just going to hit B for begin, N for end. Let us zoom in a bit. 0045

We do not need to show this. Let us hide this, our modes here.0052

So, we are just focusing this one render queue area. 0060

So, we are going to press zero. So, it is kind of fast. 0064

So, let us say that we just wanted to create the illusion of moving in really fast, trucking in, and panning in, zooming in.0072

We are just going to open up our key frames here and we are going to set position, scale.0081

Let us say we want to zoom closer into her face, for instance, or the gun. It is a focal point.0093

Set some key frames here. Now, all we are really going to do is just, sort of, scale in.0100

So, we can grab our scale. Pull it to the right a bit, scale in. 0106

Just try to imagine what the camera would be doing.0116

And we are going to move this down a bit and we are going to hit RAM preview.0119

So, you, kind of, see like we are just kind of creating the illusion of camera moving in.0127

It is real basic technique and you can play with that. 0132

I want to zoom in fast. You can go even tighter here. 0139

You can grab your values here or you can hold down shift to hold, to keep your proportions locked. You can do it this way.0146

So, let us say we want to go even tighter. We are just, kind of, scaling out.0159

In some cases you cannot scale out to far because your image might get pixelated. 0165

So, I think the general rule is around 30 percent. Let us go give it a shot.0169

Sometimes it do kind of move your key frames and tighter.0179

Zoom in and you kind of pull out slowly.0184

So, I just gave you, kind of, the basic idea with basic transformation. 0193

Now, we are just using the position and scale key frames.0196

If we want to add in rotation we can create key frame here. 0200

Go back to your beginning position.0208

We can even do a little bit of a rotate on that if we wanted to. Open this back up.0210

I think I have mentioned before, if you hold on P or you are on the layer you just get position or scale or rotation.0217

So, position key frames are for rotation key frames and as for scale.0226

You can also hold down shift R. So, you just want those two values to show up.0233

Keep pulling on shift. You get all 3.0239

So, let us add another key frame here. Let us rotate this actually.0242

Turn it here. We have to move this up a bit.0251

We are going to have toggling between my move tool and my rotation tool VWVW. So let us play that.0256

So, as you can see it is just a basic way to zoom in or zoom out of an image.0268

We use this, a lot in text, shapes. It is very basic.0273

Until we get to the 3D cameras this works pretty well.0278

OK, thank you for watching educator.com. I look forward to our next lesson.0281
