Skills and points for attention in shooting public service advertisements

In my opinion, the public welfare film, as its name implies, is an advertising film serving the public, with publicity as the main tone.

Therefore, the public welfare film must first have a theme, what to promote, what to advocate, what to promote, and so on.

Then use pictures and language to express the theme. Since it's an advertisement, it won't take long. This should make the pictures and language concise and easy to understand. Of course, it is best to be creative and unforgettable.

Public welfare films should be emotional (this sentence seems to be nonsense), the theme should be arguments, the content should be arguments, and the arguments should be convincing. Choosing controversial phenomena in society as arguments will naturally lead to no results. If you choose a good subject, you'd better find some practical news to expand your imagination in order to avoid vulgarity.

And most importantly, don't destroy the environment just because of making public welfare films.
