Valve’s 10-day long tournament for their smash hit Dota 2 game was held in Bucharest’s largest stadium, the 50,000 capacity ‘Arena Națională’, and assembled the world’s top-ranking teams to battle it out on screen for a world record-breaking prize pool of over $40M. The virtual part of the event was produced by virtual production company Myreze, who turned to Pixotope to help leverage the power of Unreal Engine in a live and complex broadcast environment. 
In a true test of Pixotope’s stability and reliability, the 10-day live production saw 18 teams and their in-game triumphs and tragedies across 22 matches, generating a huge 125 hours of live content, and more than 2000 hours of content overall.
The production featured a main AR stage and four analyst green screen studios (for English and Russian language) in Bucharest, one remote studio in Brazil (Portuguese) and another in Peru (Spanish). An LED screen with a virtual set was also in play for the tournament’s largest audience, China. The set also had functionality to show off the players’ chosen game characters as 3D AR elements, seemingly present in the same environment. This lineup of heroes was also mirrored on the main physical stage in Bucharest in front of the players, and was also visible to viewers watching from home.
Underpinned by 19 live and back-up Pixotope engines and bolstered by their on-site and remote support, presenters were landed into a multi-level virtual environment that provided a seamless viewing experience between game and commentary through virtual monitors, which included Pixotope’s data visualization tools for supporting data integration. This production had to reach an expected global viewership in the hundreds of millions with graphics from Myreze transporting those viewers straight into the action.
In total, 15 tracked cameras were used in the analyst sets and main stage. A proprietary data recording solution allowed the Myreze team to replay video and tracking data in real time, greatly aiding the fine-tuning of their creative delivery on the main stage.
“One of the trickier aspects of virtual production is that rehearsing with unfinished graphics is hard and time-sensitive. Missing a rehearsal due to technical issues when on a tight schedule, is often catastrophic. Utilizing Pixotope’s robust compositing pipeline together with our data recording racks, we were, for the first time, able to replay a rehearsal over and over again, as if we were live, iterating on the creative delivery without keeping the rest of the production hostage. This was crucial for our ability to deliver polished content on a production of this size,” said Myreze creative director Frank Vedvik.
Because Pixotope doesn’t require pre-rendering, Myreze could make immediate last-minute changes to data-driven tournament graphics, motion capture and camera tracking with ease. This unique flexibility of Pixotope enabled panelists to have featurettes constructed on the fly, with virtual segments taken from idea to on-air, within the hour.
The 2021 Dota2 International broke all previous viewing records with the grand final watched live or replayed by 100 million unique viewers across all platforms (excluding China, its largest single market) making it the most-watched Dota 2 event ever. The figure represented a 37 per cent increase over its peak in 2019 and according to the Esports Charts, the tournament finished its run with the third-most viewers ever for an esports event.
“With esports developing into a global entertainment phenomenon, we are thrilled that Pixotope was able to support virtual production of the world’s largest esports event. The collaboration between Myreze and DOTA 2 heralds a new era of innovative virtual experiences that truly enhance fan viewership and participation, and we look forward to seeing how they take esports broadcasting to new levels in the future,” Pixotope CEO Marcus Brodersen.
“We have done a lot of exciting productions in recent years, but there is no doubt that esport takes TV productions to a whole new innovative level,” Myreze CEO and founder Björn Myreze.
