I think text is better when you already know what you're looking for and video is better when you are still trying to develop an intuition for the subject.
Like everything in life, YMMV, and everyone learns differently.
Its simply the same stuff you would put in an article communicated at a fraction of the speed with less editing for brevity and prose because it's much harder to reorder video or reshoot instead of swapping a few words.
It is probably worthwhile primarily because it makes a stronger emotional connection which is to say its a more effective vehicle to deceive and manipulate you.
If you think videos are better for learning value obtained per minute I would be interested in reading the proof and can certainly keep an open mind but I'm not inclined to value an anecdote.
I used to think so too. Then I saw how my child learns stuff with far greater command of underlying concepts and connections through video and realized it's probably just a function of how I learned to learn or am used to growing up without essentially videos on any topic available on demand.
I have observed that the learning my child acquires through video is actually not "book learning" (the term exists for a reason) but much more nuanced, vicarious and realistic in a way text simply isn't. If fact, my child's goto for understanding something "let us search for a video on YouTube that will teach us how to do X". From an information theory standpoint this also makes sense.
So let's allow for the possibility that our opinions are simply shaped by our experiences of growing up without readily accessible video and reality for our children may be different.
