How do people who make short videos come up with various ideas or plot lines?

At school, the film and television teacher told us a sentence: "Imitation is the only shortcut to success". Who said the exact words and forgot them? Then this sentence is very meaningful, and the creative thinking is basically based on this principle. Of course, it's not just copying. Increase reading, including wonderful copywriting, creative advertising videos, etc. , will give you some inspiration at some point. After all, everyone's experience is limited. For example, when you receive a case about outdoor, you don't even know the equipment you need. How can you make an accurate, creative and hot video? It can only be obtained through various information channels, such as basic knowledge, basic industry overview, etc. During this period, you will see related ideas and so on, and the basic expression will take shape. Of course, this is only my way, but it is necessary to increase the knowledge reserve.
