Sophisticated and workflow-oriented multichannel recording in one flexible, expandable and enterprise-grade client-server capture solution. Support for SDI, HDMI, NDI®, SRT and UDP source formats to be recorded independently or concurrently, including proxy file creation and growing file support. Please consult the NLE vendor’s notes about codec/container compatibility.
