It doesn’t do much for their credibility that whoever made that video can’t tell a crow from a raven.
never more ...
They both have very unpleasant calls, and are probably related in some way. I only know from Jerusalem ravens, which have two colors, dark brown and grey, not those all-black European ravens.
From what I’ve been told the primary way to differentiate a crow from a raven is by their flight feathers.
Crows have 12 flight feathers and ravens have 13.
So, when it comes down to it, the difference between a crow and a raven is a matter of a pinion.
