One of the most common motion graphics jobs is to create a flying logo: taking a client’s flat, two-dimensional print logo, turning it into a 3D object, and animating it onto the screen for a wide variety of video destinations (trade shows, press events, training videos, web and social media, etc.).
This process used to require buying and learning a 3D application, rendering your 3D footage, and bringing it into After Effects (and/or your non-linear editor of choice) to integrate it with your other footage.
