The primary goal of previsualization is to help filmmakers, directors, and other key crew members plan and visualize the intended outcome of a film or scene before committing extensive resources to actual production. Animatics are a step beyond storyboards. They involve adding basic movement and timing to the storyboard panels.
In complex productions involving heavy visual effects, I create a 3D animatic in Maya or Unreal. This allows for a virtual environment where cameras can simulate shots with high accuracy.
During previsualization, I consider the movement of actors, camera positions, and blocking. This choreography ensures that actions and interactions are well-coordinated with editorial and stunt departments.
On "Wicked" and "Wicked: For Good," I helped create the monkey transformation and other sequences.
