This presentation and demo will show you how to set up your Vcam app on your iPhone to be used as a simple virtual production setup. The goal here is to create a setup to teach Virtual Production concepts to students in a classroom or simple green screen environment. This is also helpful to schools with limited budgets and no access to LED video walls and professional level equipment.
