Similar to VideoScribe is PowToon. The main benefit of this product is that the desktop version is free. “PowToon is the best free animated presentation online software tool and PowerPoint alternative that supercharges your business presentations and animated video marketing!” Other benefits include the animations which allow you to create a storyboard / comic strip production which is useful.
Again you can subscribe to this product to produce videos without branding and of higher quality if required.
I have used this product to create introductory videos for particular topics/themes for lessons which can be then embedded within your VLE.
