There are about 1 billion videos on Youtube. But it's unbelievably hard to find the right ESL videos. (ESL, English as a second language, EFL, English as a foreign language. )
Videos on Youtube are not well categorized/classified for ESL searching. They are not reviewed by ESL teachers either. I did it and share it. All videos are free. It saves ESL teachers a lot of time and makes ESL teaching easy.

Most of the videos are for "scanning". Students only need to see and have an impression of what language used under what circumstance. Students can also try to imitate/copy if they want.
The more videos about the same topic they see, the better they may grasp the language.
It's better for ESL students to focus on learning what search engines, translations, dictionaries, articles, news videos, or lectures are unable to provide, e.g. actions, descriptions, feelings, the ways that native speakers express under certain circumstance, listeners' possible interpretations and reactions, social acceptability, etc.. ESL students have to see, hear or even experience or practice the way of life native speakers live and feel to learn them. All ESL students may face the obstacle or interference from their own native language, social norms and values, more words simply don't work.
