This generally looks great!
I hadn’t been expecting a professional narrator (at least, I assume that’s not your voice, unless you were born to narrate YouTube videos). He does sound a little bit matter-of-fact in some places (like he’s trying to sell me a product instead of expounding on the wonders of scientific development), but I think his presence is still a strong net positive.
A few notes -- I’m avoiding tiny notes for things not worth editing, but thinking about ways to improve future videos:
When you mention the drop in extreme poverty being reversed, I think it comes on pretty suddenly. Many or most people don’t actually know that poverty was quickly falling. When you have good news to share (even in the context of bad news), I think it’s important to make that clear—a big part of EA’s appeal is that we’ve actually been seeing things get better.
The “Al Qaeda pursuing bioterrorism” point had no real detail and no clear external source. If you don’t have time to get into something like that, consider making sure it shows up in a “sources” document you include alongside the video.
Things I really liked:
The graph lines moving around when you were comparing an engineered to a natural pandemic—very simple, very clear visual!
Same goes for the graphic showing how bioweapons can easily backfire.
The really high proportion of the video dedicated to solutions—that’s not typical of this genre, but it really feeds into the EA spirit of the project.
