What is Virtual blocking in virtual production?

Virtual blocking is an invaluable tool in virtual production, allowing filmmakers to design shots, plan action and create immersive environments with ease. It refers to the use of previs (a process of creating a 3D model or animation of a shot before filming) to create a virtual environment that the crew can block their scenes without ever having to leave their computers. 

By using previs software such as Unreal Engine and Unity, filmmakers are able to craft out exactly how they want each scene to look like in advance, creating a realistic and accurate visualization of what the shot will be on-set. This allows directors to direct actors more efficiently while also being able to make changes at any time during the shooting process if needed. In addition, it eliminates potential mistakes or risks associated with traditional physical blocking, meaning that scenes can be blocked much faster and with far fewer resources required.

Using virtual blocking, directors have access to many different tools including motion tracking, camera calibration, lighting simulation, depth of field control and even pre-made elements for rapid storyboarding. With these features, not only does it help directors get their vision down quicker but it also offers them greater flexibility to experiment with new ideas and techniques that would otherwise be impossible or incredibly difficult when working with physical sets.
