To herald the European launch of Call of Duty: Black Ops 4 in 2019, video game company Activision enlisted Gamereactor to produce and deliver a special e-sports event whose workflow was based around NDI video connectivity technology and BirdDog’s encoder/decoders.Â

Challenge
It was inevitable that expectations would be high surrounding the 15th instalment in the Call of Duty series when Call of Duty: Black Ops 4 was scheduled for 2019. But those expectations extended far beyond the game itself and meant, for example, that the online launch event had to be seamlessly well-produced and professional.Â
Â
To deliver this event, Call of Duty developer Activision engaged the services of Gamereactor, a Scandinavian online media network covering video games in multiple languages. The primary challenge facing the Gamereactor team was to deliver ten Playstation 4 console feeds into a live production computer enabled with vMix live video streaming software, as well as a live camera from the stage that was to be used for interviews throughout the event.

Solution
Gamereactor’s technical team faced a choice: traditional routing with SDI converters and a beefy machine, or a sleek, modern, all-IP solution.Â
With time tight and expectations high, they opted to leap ahead. For the production and live-stream, the Gamereactor team opted to base its workflow around NDI technology and a total of 11 BirdDog Mini encoder/decoders, which were designed around BirdDog’s custom NDI silicon chip.

The Play-by-Play Solution
Â
- 11× BirdDog Mini units—one for each of the 10 PS4s plus one for the stage camera.
- All HDMI signals went into BirdDog Minis, then encoded over full-bitrate NDI onto a central Ethernet switch.
- A single Cat‑6 cable brought all streams into a vMix live-production PC.
- vMix handled live switching, picture‑in‑picture, overlays, and streaming—all with sub-frames of latency.
Dóri Halldórsson, who at the time of the project was a Video Editor & Content Creator for Gamereactor, explained the thought process behind the decision:
We had the option of going old school and buying a bunch of SDI converters, converting all those HDMI signals to SDI, and then getting up a more powerful computer to handle it. But clearly the best option was to embrace the future and go with NDI, which is what we did. And this approach saved a lot of headaches.
Outcome
This wasn’t just a press event—it was a case study in IP-first live production, showing the gaming world that broadcast-grade streams don’t require broadcast-grade hardware. It highlighted how NDI simplifies multi-source workflows, fosters adaptability, and provides high-quality output without technical debt.
Â
Rock-solid broadcast: Zero-major dropouts.
Rapid setup: Plug-and-play with no extra processing load.
Scalable architecture: Simple to add more sources or re-route.
Mega impact: Call of Duty: Black Ops 4 set the record for Activision’s best-selling digital debut—beating even WWII
