A recent process used by many prominent directors is the use of 3D visualization. I was a CG Supervisor at Electronic Arts for many years and can bring years of 3d CG experience to the project. We can work out camera angles, animation, lenses and realistically block entire scenes on the computer. The benefits are enormous both creatively and budget wise.
Pre-vis allows you to block out and experiment effortlessly with any of your scenes. It can illuminate exactly what needs to be shot for action scenes, or to help with lens and rig decisions in specific environments. Will a 18mm lens get the top of the roof and the floor in at the Yankee Stadium? What does a 35mm lens look like on X car with a hood mount? We can figure that out without getting either the camera or the vehicle, or the stadium.
Not only can you figure out camera / lens / editing decisions beforehand, but it can drastically help reduce set decoration since you know exactly what’s in frame.
