I believe a great Explainer video starts with a great script. While it’s true you definitely need strong visuals, the script needs to be equally compelling. I love recording scripts which are funny. However, while humor is great, and a touch of humor is probably necessary, the purpose is to explain something, not solely entertain. I believe it’s the job of the narrator to complement the visuals and fit right in. Being natural, heartfelt, and conversational is key.
