What does a Keyframe represent in video editing?

A keyframe represents a specific point in animation within video editing. When animating a particular element, such as position, scale, or effects, keyframes are used to define the starting and ending points of that animation. By placing keyframes at important intervals, the software can interpolate the values in between, creating smooth transitions and movements over time. This concept is fundamental in both animation and video editing, as it allows editors to dictate changes at specific moments, effectively controlling the evolution of visual elements throughout the scene.

In contrast, a transition effect pertains to how one clip changes to another, such as cuts or fades, and does not specifically denote a point in time like a keyframe does. A color setting for the video title deals with text formatting rather than animation, and a tool for audio mixing involves manipulating sound levels, which is unrelated to the definition of keyframes in video editing contexts.
