Depends on what you need. I was once able to fix my toilet watching an Indonesian video. I understood approximately zero, but I could still follow that guy's hands. It is a different story with programming or other abstract/text-based tasks, but when it comes to anything done with hands, I like a video better. 3blue1brown videos on maths are beautiful as well. I wish I had them when I was 18.
