I think in this special case, it's much faster to google and read instead of watching a relatively long video.
For example searching how to save a Vim-macro yields this very useful result: http://vim.wikia.com/wiki/Macros

On the other hand, watching a person do the task can be a nice "breakthrough" from the eyes of a noob.
For example, I've watched some https://www.destroyallsoftware.com/ videos. I could have read an article that says the same things, but you get a nice context for the reasoning. You see the thing happen. It's nice for the programming perspective, perhaps not for looking up certain macros.
Forcing myself to use Vim everyday for everything for a few weeks (and all the vim-related googling that ensued) sure helped me a lot more than these screencasts.
But again, those are very exciting and it sure helps to stay excited when you have a mountain to climb.
