From my hometown, there is a words: The tree trunk is more important than the leaves. The dense tree may look pretty, but without a tree trunk, it means nothing. The Lesson Plan is not definitely a tree trunk, but it is hard to prepare new knowledge without the lesson plan. You may forget some key points when you make a PPT. Also, making a lesson plan will encourage people to prepare early, not suddenly finished.
Thus, in my opinion, the lesson plan is essential to start new content.

For example, when we are writing an essay, it is best for us to prepare the outline first, clearly understand our subject, and relate to the writing subject.

This video is the lesson plan about Human Development Index (HDI). This is an economic index, and which is related to my major. This is the reason why I want to introduce it. Also, this index is important to all people who live in different countries.
The video content includes an interactive question. In my opinion, H5P is very effective and more interesting for multimedia learning. Students will focus on the content. At the same time, the creator can think more deeply about which question can be useful. This is a win-win result.
