@lelek yesterday I fought 2 hours against a couple of pieces of software, just to obtain a low-quality video without audio 
Sorry but gaining the needed expertise requires much time that I don’t have
Consider that I work hard, and my scarce spare-time must be shared between nature photography, music composition to relax my mind, and cartoon drawings
For example this Mad DJ…
Animals…
Or the Yeti
So I will not make a video, but I’ll certainly try to make better written/photographic explanations
