Previsualization (aka “previs” or “previz”) is a crucial step in the filmmaking process that enables directors, producers, and technical crew members to plan and visualize their projects before filming or animation. Using software like Unreal Engine, previs allows filmmakers to create a rough draft version of their media project, saving time and money while improving the final quality. With previs, filmmakers can preview their film and make necessary adjustments before shooting starts, ensuring that the final product meets their vision. Previs provides filmmakers a valuable opportunity to refine their ideas and make informed decisions before production.
