Frames, keyframes, and inbetweens
Animation comes from the Latin word animātiō, which means the act of giving life. It is the simulation of movement created by the sequence of several drawings, one placed after the other, that when played all together, allows us to see the magic happening. However, this movement doesn't exist, and it's based on the persistence of vision we talked about earlier in this chapter.
Frames
In computer animation, these sequential drawings are called frames, so every single drawing needed to create the illusion of movement is a frame itself. And not only that, but frames will also determine the duration and the quality of our animation. So, imagine we want to move an object from point A to B in 1 second. We can choose the number of frames we want to use, but let's see the difference. Let's move a ball from point A to B in 1 second using the following number of frames:
- Option 1: 25 frames
- Option 2: 5 frames ...
