Coursera is excellent for it—any Coursera courses have playback speed options. I usually go x1.5 for sciences and x2 for humanities(since humanities tend to have lower information density), but you can vary that a little depending on the prof’s talking speed and the content of the lecture you’re watching.
I know Coursera isn’t the only source of informational video, but it’s a good starting point.
