Many clients, and maybe some video companies too, like to see the script & storyboard (words & pictures) developed side-by-side, at the same time.

I don’t agree. It’s too easy to make mistakes this way.

Let me explain why:

Scriptwriting and storyboarding at the same time is too confusing, there’s too much to consider to complete it all in one session.

I find when the words and pictures are developed at the same time, it’s easy to get 80% of it right. But to get 100% right is too plain difficult.

So divide your pre production into 2 parts:

1: Scripting, ie, agreeing the right words

2: Storyboarding, ie, agreeing the right visuals.

Do them in 2 separate stages and there won't be any confusion.

Remember - there’s no hiding place in a video.

Everything is seen and everything must be perfect.

So take your time, and approach it in an orderly manner, as a sequence, and not a dubious shortcut.
