Computer generated motion graphics


The term motion graphics originated with video editing in computing, perhaps to keep pace with newer technology. Before computers were widely available, motion graphics were costly and time consuming, limiting their use to only high budget film and TV projects. With the reduced cost of producing motion graphics on a computer, the discipline has seen more widespread use. With the availability of desktop programs such as Adobe After Effects, Discreet Combustion, and Apple Motion, motion graphics have become increasingly accessible.

The term "Motion Graphics" was popularized by Trish and Chris Meyer's book about the use of Adobe After Effects, titled "Creating Motion Graphics". This was the beginning of desktop applications which specialized in video production, but were not editing or 3D programs. These new programs collected together special effects, compositing, and color correction toolsets, and primarily came between edit and 3D in the production process. This "in-between" notion of motion graphics and the resulting style of animation is why sometimes it is referred to as 2.5D

Motion graphics continue to evolve as an art form with the incorporation of sweeping camera paths and 3D elements. Maxon's CINEMA 4D is known for its ease of use, plugins such as MoGraph and integration with Adobe After Effects. Despite their relative complexity, Autodesk's Maya and 3D Studio Max are also widely used for the animation and design of motion graphics. Maya — traditionally used for high-end special effects and character animation — has the advantage of including an extremely robust feature set and wide-ranging user base. 3D Studio Max has many of the advanced features of Maya and uses a node-based particle system generator similar to Cinema 4D's Thinking Particles plugin. There are also some other packages in Open Source panorama, which are gaining more features and adepts in order to use in a motion graphics workflow. Blender and its node-editor is becoming more and more powerful.

Many motion graphics animators learn several 3D graphics packages for use according to each programs' strengths. Although many trends in motion graphics tend to be based on a specific software's capabilities, the software is only a tool the designer uses while bringing the vision to life.

Lending heavily from techniques such as the Collage or the Pastiche, motion graphics has begun to integrate many traditional animation techniques as well, including stop-motion animation, cell animation or a combination of both
