I’m not sure I would try earning a degree online. You should really check to see if there is an art institute or something in your area if you really want a degree. If you are just interested in learning After Effects or something, then you might want to just pick up a video training series like Total Training. And from what I understand, having a degree in this industry doesnt really mean much. Your demo reel is much more important.
But you probably shouldn’t listen to much to me. I’ve never been to art school, so I dont even know what they teach, I’ve also never had a job with motion graphics. I’m just a motion graphics hobbiest for about 2 years now (video editing in general for about 4 years). But some of my friends who have gone to school for it often ask me how I manage to pull off certain tricks in my work 🙂
