Immersive Design Studios unifies live event broadcast looks with AJA ColorBox

Immersive Design Studios’ Canvas platform combines real-time game engine and cloud technology with video capture, playback tools, and artificial intelligence (AI) neural networks to ensure immersive live event activations. Immersive Design Studios works closely with clients to support every production and broadcast or stream it live. To achieve a uniform look for broadcasts that comprise footage shot on different cameras, the team deploys AJA ColorBox with Assimilate Live Looks for live grading, most recently for Worre Studios.

“We’re constantly brainstorming ideas and testing them across client projects”, says Immersive Design Studios Co-Founder and CEO Thomas Soetens. “When we started thinking about Worre Studios and began LUT (lookup table) work, we realized we could use our cinema cameras with AJA ColorBox and Assimilate Live Looks to push the loads. We ordered multiple ColorBoxes and were using them with Live Looks in under a week.”

Worre Studios - a Canvas-powered facility that’s been tapped by Fortune 500 companies, celebrities, and more for live hybrid in-person and virtual events - features a circular LED stage. The venue comprises four LED walls - each 60 feet wide and 14.5 feet high - totaling a combined resolution of 38K. It accommodates an in-person audience of up to 350 people, as well as the capacity to reach 500,000 virtual attendees. Canvas outputs the experiences onto the LED walls, but most often, everything that happens in-studio is also broadcast or live streamed to remote audiences.

Ensuring a Hollywood-caliber viewing experience on a production like this meant that anywhere there was an interaction between the LED wall, speaker, and virtual production background, the look had to be uniform. Soetens and team leaned on LUTs as a solution because they support camera calibrations that move beyond adjusting the white point and an even balance between the colors. They output feeds from ten different cameras through a video mixer and into AJA ColorBox units, which helped them unify the look and feel of the color to a prespecified LUT the team wanted applied to the broadcast.

“Our ColorBoxes sat between every camera and the switcher in a very simple way, introducing essentially zero latency and making them quite handy kit”, says Soetens. “We just had to configure the devices and talk to them over the network, and we got powerful outcomes; they’re small and portable, so we could place them anywhere and access them remotely via the browser-based web UI. This approach gave us far greater control over the outcome.”

Establishing a uniform look when working with a broad range of cameras, however, can be challenging as each camera has unique attributes. Recognizing that learning multiple camera models and brands, and their different LUTs and calibration approaches, just wouldn’t be efficient, Soetens and team saw ColorBox and Assimilate Live Looks as a centralized solution that would allow them to unify and color grade footage from multiple different camera types with low latency. “We were able to swap the look and feel between shots and make every camera source ultimately look the same”, he says. “It allowed us to deploy multiple LUTs on multiple ColorBoxes, test them, and bring them together seamlessly for a cohesive program output.”

In addition to using AJA ColorBox, Immersive Design Studios leverages many other AJA solutions across projects from Kona I/O cards to FS frame synchronizers, Mini-Converters, and, more recently, Bridge NDI 3G. “Bridge NDI 3G is a symbiotic fit for a lot of our clients”, says Soetens. “Especially considering Canvas can ingest hundreds of NDI streams; most of our clients are using it as a set-and-forget solution for SDI to NDI encoding/decoding needs.”
