Keyframes are often used for things like animation, fades, and effects. But most users don’t understand them. Here we’ll explore a couple of the major methods keyframes interpolate (or blend) from one to another.
The Hold Interpolation style is an additional interpolation method that is available only for temporal (time-based) properties. This style of keyframe allows a keyframe to hold its value across time without a gradual transition. This is useful if you want to create staccato-type movements or make an object suddenly disappear. When used, the value of the first keyframe will hold until the next hold keyframe is encountered, and then the value will instantly change.
