It's fine to make a video, but if your work is serious at all, it should also be in written text. It's much quicker to read than listen to someone talk. I'm sure there are exceptions where video format makes more sense, but, as a rule, it's incredibly stupid.
When I use should like this, I mean that it's the only sensible thing. They can do what they want. I don't view their content anyway, so it's no skin off my teeth.
