Immersive Virtual Concerts: XR, LED Realistic Virtual Production, and Cloud Streaming Technologies

Last April, Grammy‑winning artist Travis Scott held a virtual concert called “Astronomical” inside the game world of Fortnite. The event attracted 12.3 million concurrent players, setting a record for live music streams in the game.

Driven by advances in film technology and the pandemic, online concerts have become a major trend. Artists such as Billie Eilish, Blackpink, and TFboys have all performed virtual shows, which offer dazzling effects, strong immersion, and low participation barriers.

Internet platforms are rapidly investing in this market. On March 8 2021, iQIYI launched its “Cloud Concert” product, debuting with the idol group THE9’s immersive virtual performance “City of Illusion”.

The concert relied on XR (extended reality) technology, which blends real‑world LED screens with engine‑driven real‑time rendering to create a seamless virtual stage. AR effects were added to the foreground, and multiple XR virtual camera positions along with film‑grade equipment raised the production quality.

Key technical highlights of the “Cloud Concert” include:

LED realistic virtual production: high‑resolution LED panels (pixel pitch 2.6 mm) replace traditional green screens, delivering photorealistic lighting and depth.

Digital scene capture: centimeter‑level 3D scanning, multi‑camera depth acquisition, and algorithmic reconstruction enable precise virtual environments.

StageCraft‑style real‑time rendering: the virtual set is rendered live, leaving no room for post‑production, which raises the challenge for latency and synchronization.

High‑concurrency streaming: an AI‑assisted monitoring system, intelligent scheduling, and a nationwide CDN covering all operators support massive simultaneous viewers.

Interactive features: live audience screens, real‑time video links for up to 300 participants, and AI‑driven content safety checks.

Hardware requirements are stringent; the LED panels used have a smaller pixel gap than typical displays, and the system’s refresh rate minimizes visible seams. iQIYI has been building a virtual production base since 2020, testing hardware reliability such as screen manufacturers, steel structures, and floor rigs.

Beyond the current capabilities, the article notes that achieving millimeter‑level digital assets would further narrow the gap between virtual and on‑set filming, making virtual production comparable to shooting on a physical set like Hengdian.

The piece concludes that virtual production will reshape content creation, linking diverse topics through a shared virtual world and spawning new IP opportunities.
