Rewind and re-recors is what makes it different. But that's it.
Perhaps its just my high expectations and the fact I already own half a dozen screen recorders.
Ability to pause and go back and re-record last part of video is what makes it different from other screen recorders. Otherwise recorder is very basic and I would love to see more functionality. For example, annotation tool needs some work. It is unintuitive and I'd want it to be hidden until I need to use it. Also I'd want camera window to be more adjustable - not just resizable rectangle but other forms, too - circle, square etc. Also possibility to record just part of creen would be nice. And those are just basic things many other recorders have.
But I will keep the tool to see how it develops as it good priced.
