In animation or video production, what are keyframes used to record?

Keyframes are crucial elements in animation and video production, serving as markers that define specific points in time where particular changes occur. By placing a keyframe, you essentially record critical action points in transformations, such as position, scale, rotation, or any other property being animated. This allows the software to interpolate the changes between keyframes, creating smooth transitions and motion.

When animators set keyframes, they specify the starting and ending state of an object or effect at designated points in the timeline. The system then calculates the intermediate frames, which is how fluid motion is achieved. This is essential for creating dynamic and visually engaging animations, whether for character movement, transitions between scenes, or effects.

The other choices refer to elements that do not directly relate to the concept of keyframes. The minimum frame rate pertains to how often frames are displayed per second, color balance settings address the visual hues and tones of a video, and audio synchronization points focus on aligning audio with visual elements, none of which utilize keyframes in the same way as recording key action points in transformations does.
