I remade this video. Link to my new and much improved video: https://youtu.be/-1LJfZglFy8
If you have learned the beginner method to solving the Rubik's cube and really want to improve your time significantly, the only way to do that is to learn the OLLs and PLLs. There are a lot of these and it can get overwhelming, so I've narrowed it down to the minimum possible algorithms to learn to begin solving the Rubik's cube in the 30-40 second range.
