Let me introduce myself. My name is David Cassidy and in my role as the Green Screen Guru I would like to share my over thirty years of experience of Virtual Studios and Green/Blue screen keying and compositing. This website will introduce you to my background, projects past and future, services I offer, clients, and a contact form to build a database of users to enable the sharing of expertise, operational tips and content you are proud to share.


After the uncertainty of IBC 2016, Blackmagic Design presented us with a product in the great tradition of Ultimatte.
A 4K capable device that offers the usual faultless keying plus a range of tools to allow the creation of the completely convincing composites Ultimatte is renowned for.
All at a price that means every level of producion can benefit.
