Please understand the difference between narrating what you do and doing something to show your idea or opinion, or reason, or purpose. We need narration or description. The language in videos should be copyable or imitable. Artists should explain less but give more examples so that students could copy or imitate without first learning the meaning of the language. When producers make ESL English videos, it's better to teach students to do something. It makes it easy to remember the whole thing and the related languages.
