Storyboard the shots, movements, and interactions
A storyboard is a graphic organizer that plans a narrative. This is where you can take your written story outline and translate it into the specific shots, movements, and interactions of your characters. This is a visual outline of every scene you plan to capture.
This is also a good place to ensure your video will make sense. If someone doesn't understand your storyboard right now, people may not understand your finished video once it is complete. Use as many frames as you need. Be thorough.
