I can't really bring myself to watch recordings of speeches. I feel like, when you're making an actual speech or lecture, you benefit from slower pace because the audience can't rewind in case they miss something, probably they have lots of distractions, not to mention being physically uncomfortable in a slight but annoying manner for one reason or another. Meanwhile when making video content or even a podcast, it's better to be fast-paced, because there's a decent chance you have the audience's full undivided attention in a place where they feel most comfortable with zero distractions (sofa at night with maximum brightness TV), and even if they miss something, they can rewind, or pause, or whatever.
