Chapter 7. Animating with Keyframes > Understanding Keyframes

Understanding Keyframes

The concept of keyframes is quite straightforward. A keyframe is a fixed value of a parameter at a specific point in time (Figures 7.1 and Figure 7.2). For example, you can set a keyframe so that an object’s Scale parameter is set to 50 percent at 10 seconds. Or a Gaussian Blur filter’s amount is set to 4 pixels of blur at 12 frames. Or an Oscillate parameter behavior’s amplitude is set to 10 pixels at 1 minute.

Figure 7.1. A keyframe represents a specific value for a parameter at a specific point in time. Here, values for the Position, Rotation and Scale of the leaf have been set at the first frame and at five seconds.
