"Pre Visualization is is a collaborative process that generates preliminary versions of shots or sequences, predominantly using 3D animation tools and a virtual environment. It enables filmmakers to visually explore creative ideas, plan technical solutions, and communicate a shared vision for efficient production" This is the definition phrased by the VES (Visual Effects Society)
This field is primarily been the concern of the VFX directors and supervisors, until now. As time and money are key factors in film production, it behooves you, as a director, to become familiar with this process. Pre Vis is an excellent way to plan your production before you even set foot on a set. The documentry has a great segment that promote the use of pre vis outside of action sequences and heavy vfx. Watch and share your thoughts. - Eve.
