Qube Cinema streams 4K 3D from single server


For the first time, Qube Cinema delivered a high-bit-rate 4K stereoscopic DCP through two Barco projectors in a demo at the Moody Gardens Digital Cinema Symposium in Galveston, Texas.

Exhibited on an 80’ by 60’ giant screen, the demo used a standard Qube XP-I server paired with Qube Xi 4K Integrated Media Blocks (IMBs) installed in two Barco DP4K-32B projectors. The Qube system played back an 800 Mbps DCP, more than three times the maximum DCI bit-rate specification of 250. The data speeds of the Qube XP-I server make it possible, for the first time, for a single server with one DCP to drive two projectors, each with their own IMB.

"Seeing the film in 4K 3D was a startling experience," said director Melissa Butts, speaking about her latest movie, Space Junk 3D, which was shown at the Symposium. "All the hard work we put into shading, lighting and textures was that much more brilliant and remarkable… With all the detail, everything just looks and feels more real."

Qube Cinema also demonstrated the high-frame-rate capabilities of the Qube XP-I server with 2K stereoscopic content on the giant screen. This demo compared 3D material at 24, 48 and 60 fps, including side-by-side split-screen comparisons. At 60 fps, motion blur disappears and rich detail is clearly visible in the moving images.
