It's important as we start Motion that we go over a couple of different terms. Now, I'll cover two sets of terms, terms that are specific to the application Motion, as well as terms that are commonly used throughout the Motion Graphics industry. So let's start with Motion specific terms. An object. Whenever you add something to your project, whether it's text or an image or footage, that's an object, and that object resides on a layer. Layers reside in a group. Then behaviors are tool specific to Motion that allow you to create organic animations without the use of keyframes.
The Replicator is a tool that replicates objects into a pattern. You can replicate things in two dimensions or even three dimensions. Parameters are units of control for a layer or a group within your Motion project. So to go over some more common terms, we'll start with a Particle System. This is a system made up of sprites, little tiny reference objects. Those sprites create particles, and those particles are part of an emitter, and the emitter has emitter cells.
And trust me, we'll cover this a little bit more in the Particle section. Filters, also known as effects, generally alter both images and audio in someway. Now in Motion, we're only dealing with video filters. Cameras. These are virtual representations of real cameras built into the software. Lights. These are obviously lights built to simulate real world lighting. Composite. This is a combination of layers and groups. It's a technique commonly used in motion graphics. Blend mode.
These are mathematical calculations for how the pixels of different layers or groups interact with each other. It's a great way to blend all the different elements in your project. Luma. This is the black or white value of an image. Often used when referring to the brightness of the video signal on a monitor. Chroma is the color value within a video signal. So Chroma and Luma actually combine to create your video signal you watch on your television. Key. This is a method to remove part of an image based on Chroma keys and Luma keys, and there is even one specific to pulling green or blue screen keying called Primatte RT. Matte.
This is a black and white image. Whatever is white remains, whatever is black becomes transparent. This is typically what's generated after you pull a key. Alpha Channel, the 4th channel of an image. This determines the transparency of an object, layer, or group. Mask. A tool used to hide or reveal parts of an object, layer, or group. In Motion, there are two kinds of masks. There are Bezier masks and B-Spline masks. And also there are object masks, which function just a little bit different, where you can change anything in your composition into a mask.
So now that we've covered some of the common terms in video and in Motion, let's get started learning the application.
- Understanding the toolbar and setting the essential preferences to get started
- Adding .mov files, still images, and Photoshop and Illustrator assets to a project
- Animating with behaviors and keyframes
- Creating 3D animations with lighting accents, shadows, and reflections
- Creating simple and complex particle systems
- Creating real viewer interest with Focus Behavior and the 3D Camera Framing behavior
