I have a few short film projects that I finished originally at 2K. All were shot in 5k and now I would like to go back and finish these at 4K. I am looking to rent a facility somewhere in the Midwest (Chicago?) that is capable of rendering 4K or UHD. My options are to upgrade my current system or rent studio time and render these out. Curious if anyone has had first hand experience? Thanks in advance for any suggestions.
