Youtube! Go onto Youtube and pull up any After Effects or Cinema 4D tutorial, then go to town! That’s how I learned, I didn’t learn motion graphics in school, I studied film/tv production. Some of my favorite Youtube channels are: Grayscale Gorilla, Mt. MoGraph, and Eyedesign. These are just a few, there are many Youtube channels out there that can teach you what you need to know. I’m currently using Youtube to learn ZBrush, and Blender 2.8… as well as new things in After Effects and Cinema 4D!
