Pre-production work is important to plan out every detail of a media production so nothing needs to be changed during the actual production that could increase costs or timeline. It is essential during pre-production to continually revise and improve ideas, storyboards, scripts, and other pre-production elements until they are as strong as possible, as these elements cannot be changed once production begins. Effective pre-planning through visualization of the end goal and organized scheduling and equipment preparation helps ensure a smooth and cost-effective production process.
