How to write a narration for a promotional video

The main expression methods of commentary are narration and explanation, sometimes a combination of narration, explanation, description, lyricism and discussion. Excellent commentaries are often prose or prose poems that combine narrative, discussion and lyricism.

How to write a good commentary?

1. Grasp the main characteristics of the object being introduced, and pay attention to the use of typical and contrasting techniques to give people a sense of reality. Highlight typical examples, use contrast, combine points and surfaces, and reveal the essential characteristics of things from the outside to the inside. They are widely used in commentary.

2. Be clear-minded and explain things in a simple way. Explanations are mostly meant for people who don’t understand a certain thing, so they must be clear-eyed. What should be said first, what should be said later, and how to say it so that it is easy to understand, all should be considered. Generally, there are arrangements from general to divided, from top to bottom, from bottom to top, from far to near, from shallow to deep, from outside to inside. When explaining something in detail, you can proceed through steps such as object, concept, classification and comparison, analysis, and summary. That is, first explain what the thing to be introduced is (conception, definition, category, ownership relationship, classification status, inherent characteristics, etc.), and then explain what it needs to be and what it should be. Some also need to be introduced according to the production process. In the commentary of the documentary, due to the need for "montage" processing, it is allowed to jump as the camera "dissolves" and "disintegrates", but this jump is still intrinsically linked.

3. There must be strong feelings and the language must be vivid.

The commentary not only has the function of introduction and explanation, but also has a certain appeal and arouses strong excitement. The commentary should express strong emotions. In addition to figurative language, it can also use rhetorical devices such as parallelism, parallelism, and repetition, and pay attention to the phonology and rhythm of the language.
