Video presentations for Academic Journals

Yesterday a colleague sent me an email from the Journal of Number Theory explaining that, for the future, the authors of all accepted papers will be invited to submit a video presentation of a "talk" of their paper for the Journal's YouTube channel. To me, this makes so much sense I am sort of surprised that no one has thought of it before. We're all so busy, and watching a simple video presentation of a paper seems as if it would really provide a nice cognitive organizer for the paper, providing another "type" of learning opportunity that could deepen understanding of the paper when you read it. I like it. But will it just make reading of papers obsolete? Will the talks become like Cliffs Notes, actually replacing the reading of papers altogether? Possibly, but I think the risk is worth it. Personally, I never have time to read all of the papers that I should be reading; this would give me the opportunity to actually connect with a much wider body of research than I am able to currently.
