What is Previs?

Just read this definition formulated by the ASC-ADG-VES Joint Technology Subcommittee on previsualization.

” It is a collaborative process that generates preliminary versions of shots or sequences, predominantly using 3D animation tools and virtual environment.It enables filmmakers to visually explore creative ideas, plan technical solutions, and communicate a shared vision for efficient production.”

and i like to add “It will also help vfx artist to have some sleep.”
