What term describes the point of which something changes, including speed or color?

The term that accurately describes the point at which something changes, such as speed or color, is "Keyframe." In digital animation and video editing, keyframes are specific points in time where certain parameters are set, like position, opacity, or color. By defining these points within a timeline, the software automatically generates the in-between frames, creating smooth transitions between different states or values.

For instance, if you want to change the color of an object from red to blue over a period of time, you would set a keyframe at the start with the red color and another keyframe at the end with blue. The software will interpolate the colors in between, resulting in a gradient effect. Keyframes are essential for controlling motion and other effects, facilitating dynamic visual changes throughout a timeline.
