I’m a little late to this, but Igor Pak has a list of combinatorics videos (of lectures and seminars) and an explanation of why you should watch them, why you should let people make videos of you, and so on.
(Posting this because I happened to Google something unrelated, found a paper that Pak wrote that was useless to my actual purpose, but then remembered that I’d come across this months ago…)
