The use of Singular proved to be a game-changer for the PCL, with Mike Buetsch, Director of Broadcast Engineering & Production at, expressing that their experience using Singular was ‘excellent’. “The amount of control apps we could deploy gave us incredible flexibility, and supported a multi control room workflow". 

PCL operated 2 shows near simultaneously, transitioning seamlessly between the two control rooms. The team were able to deploy as many channels as they felt necessary, and integrating API control for automation streamlined the production process making it incredibly efficient.

One of the standout aspects of this project was its fully remote nature. Operating within a fully virtualized, cloud-based production environment, the PCL found Singular to be an exceptional companion, seamlessly supporting their setup while also providing the robust capabilities of a traditional CG engine.

Singular's cloud based infrastructure proved to be remarkably scalable, accommodating the growing scope of the show with ease while allowing flexibility as the production staff worked collaboratively to support the show.
