Usually after a music video treatment is approved by either the artist or the record label, the next step is to create the storyboards. Storyboards are a great medium to help everyone involved in the production get a visual understanding of the treatment.
Storyboards allow the director to try different approaches to a scene. Storyboards also serve as a communication tool between the production company and the artist where either party can provide input or feedback in a more contextual way than if it was only based on a narrative treatment.
Another advantage of using storyboards during production is that they are a great time saving tool. Storyboards help keep the process of filming stay focused on pre-planned and pre-determined angles and takes.
Furthermore, everyone involved in the pre-production, production and post-production process can benefit from storyboards. From actors to camera operators from lighting technicians to producers, from editors to wardrobe, makeup and hair stylists. Having a visual reference of what is being filmed and how it will flow when cut helps everyone work towards a common, organized goal.
