There are several excellent reasons to support your decision to move from graphic design to motion design.
Why Move From Graphic Design to Motion Graphics Design?
More exciting work: motion design adds animation principles such as staging, anticipation, timing, easing, exaggeration, and overlapping action to your already powerful design principles mix.
Holistic understanding of graphics technology: by working with tools and software features you are already familiar with (pen tool, gradients, layer modes, etc.) and applying that knowledge to motion, you will develop a deeper understanding of these tools’ capabilities and how their features work.
Become a master of the design universe: you will be able to take any idea and make it real in any medium: print, digital (web and devices), video, 3D, and even gaming and mixed reality.
You will be a more attractive candidate to employers: if the choice came down to you and another creative to fill a spot, and both of you have comparable portfolios and experience, knowing motion design could shift the tide in your favor.
Your boss or client says you have to: as mentioned earlier, video and motion design is growing by leaps and bounds. It is likely the ask is forthcoming, so it’s better to be ahead of the curve.
