I'd like to know how to create a video tutorial like:
Is there any 'easy to use software' to achieve such effects? I've tried AVS4YOU and other beginner animation software packages, but I don't get it.
I really appreciate any help.
Personally, I don't think those videos look very good. I certainly wouldn't take their message seriously given their poor quality.
But that point aside, many people use either Apple Motion or Adobe After Effects to create motion graphics. Motion offers "behaviors" that make moving objects around a little easier if you aren't familiar with keyframing.
