Sometimes the best way to say something is by showing it. How best to do that. It is my opinion that you should treat your audience with a degree of intelligence. Don’t show them, tell them and put the words on the screen for the same message. You can use visual and sound counterpoint to be showing one thing and saying another thereby your message combines the two and actually says a third thing. To employ this method it is important to have a good script. Even if you are doing a documentary style video you can write (or extract from the footage) a story that makes sense and treats the audience with respect and intelligence.
