zLense Demonstrates Breakthrough zKey™ 3D Keying System at NAB 2017

New Depth-Measuring System Creates Alpha Channel Without Chroma Keying


Las Vegas, NV (April 24, 2017) – zLense, a global broadcast and production technology innovator, is demonstrating its new innovative zKey™ 3D Keying System here at NAB 2017 (booth SL15713). Unlike traditional keying systems, zKey uses depth information to separate the foreground talent from the background, creating an alpha channel in real time without the need for green screens, special lighting or other limitations. This unique new capability is available to select customers through development partnerships or a revenue-sharing model with the company.


“With the introduction of the zKey 3D Keying System, we are opening new possibilities for maximizing creative flexibility in live broadcasting,” said Bruno György, CEO of zLense. “The zKey system allows for adding CGI layers in front of the talent, or between the foreground and background in real time – a process that has been impossible without a green screen until now. Because no special backgrounds or lighting are required, this capability can revolutionize the creative potential of live productions while also speeding up and simplifying content creation.”

The zKey™ 3D Greenless Keying System enhances an existing studio camera with the system’s depth camera attachment. Both content streams (full HD video and depth image) are transmitted to the zKey appliance that outputs the alpha channel and mask with a delay of only 4 frames. The system is ideal for a wide range of augmented reality (AR) applications.
