When it comes to Video Production.
Where, When, what and the Hows and whether the output will look good, is always a question.
That's where Storyboard comes into play.
Creating Illustrations in sequence with reference to light, camera and action thereby giving your production a sense of direction by cutting off whats not required and Enhancing what is required.
Going further and creating Animated storyboards called Animatics which can also be infused with Voice overs making your path even more clearer.
