Either way, it is extremely easy to produce a video like this from the program iMindMap. By all reports and predictions, similar automated presentations will be in other major mind map programs within a matter of months.
[I was making this type of animated map several years ago, first with Prezi and then my running a screen capture recording program in the back ground which I displayed a mind map. The integrated approach is far easier and quicker to implement.]
Once the professional providers of study materials for medical, legal, and nursing students get into the act (say in about 3 months) you will see these presentations everywhere. It costs almost nothing to produce these clips.
