I'm making an instructional video and I'd like to do a cut away to a very simple diagram, one step up in a hand drawing on a white board. What software should I look at? I want it to be simple with short learning curve. The subject is high school level science, so it's the kind of diagrams a teacher might draw on a white board but I want movement and a step up in quality. Otherwise I've simply shoot a white board (I may still do that.) I guess there is a lower limit on how simple animation can be, you would need to know how to keyframe and so on. I can adapt the diagram to the software. I just need simple shapes that move. I did this decades ago using film on a copy stand and hand drawn art but I don't have that much time any more.
