Motion graphic design refers to the art and technique of creating animated visuals or graphics using motion and animation principles. It combines elements of graphic design, animation, and filmmaking to bring static designs to life and communicate messages effectively.

Motion graphics are often used in various mediums, including films, television, videos, websites, presentations, and advertisements, to enhance storytelling and engage viewers. 

The process of motion graphic design involves several key steps:

2. Storyboarding: Creating a visual plan or sequence of frames to outline the flow of the animation.

3. Graphic Design: Designing and creating the visual assets, including typography, illustrations, icons, and backgrounds.

4. Animation: Bringing the graphics to life by adding movement, transitions, and effects using keyframes and timelines.

5. Timing and Synchronization: Ensuring that the motion graphics are synchronized with any accompanying audio, such as sound effects or voiceovers.

6. Iteration and Feedback: Reviewing and refining the animation based on feedback and making necessary adjustments.

Motion graphic design allows designers to communicate complex ideas or concepts in a visually appealing and engaging way. It can incorporate various techniques, including kinetic typography, animated infographics, visual effects, and transitions, to create dynamic and impactful visuals that capture the viewer's attention.
