Everything You Need to Know About Chess is a set of 5 videos prepared by chess.com. They are short videos that will give you the basic ideas and principles of the chess games. You should be able to start playing chess with these videos if you are a beginner.
If think you know about the game, they will still be valuable as a ‘refresher’ for you to know about chess. In this case you should start watching the video about opening.
I use these videos in my coaching as they are good video and I don’t believe in re-inventing the wheel.
Happy viewing and Good Chess.
