NODOS

NODOS is the real-time compositing and processing engine of the Reality 5 platform. It handles video I/O, keying, camera tracking, lens profiles, clip playback, XR processing, and production logic separately from Unreal Engine rendering. This allows Unreal Engine to focus on creating and rendering real-time graphics while NODOS manages the live video, compositing, signal routing, and output processes around them.

NODOS connects Reality 5 productions with different broadcast and display infrastructures, supporting SDI, SMPTE ST 2110, and display or HDMI outputs for workflows such as videowalls. It can also use focus-distance data from the tracked camera lens to apply depth of field during compositing, helping live talent and virtual content respond more consistently to camera focus changes.

Through the visual nodegraph interface in Reality Hub, engineers can build, inspect, and configure the complete production pipeline, while operators can access the focused controls required for reliable live operation.

NODOS Editor

  • Node-based compositing Build video, keying, media playback, tracking, lens correction, compositing, and processing pipelines through a visual nodegraph.
  • Independent media processing Handle live video, compositing, and I/O outside the Unreal Engine rendering process, helping preserve rendering resources for graphics and virtual environments.
  • Image-based keying Combine live talent with virtual studios and AR environments using clean-plate keying, 3D Cyclorama workflows, and depth-aware compositing.
  • Professional Video I/O Connect Reality 5 with supported broadcast video hardware, global video formats, HDR, UHD, and Fill and Key workflows.
  • Camera tracking and lens correction Connect industry-standard tracking systems/protocols, load calibrated lens profiles, and apply lens distortion or undistortion in real time.
  • High-performance clip playback Decode, synchronize, and route media clips through NODOS without adding video playback load to the Unreal Engine scene.
  • XR and LED volume processing Configure LED stage geometry, inner and outer frustums, automated color profiling to match the colors of set extensions, and multi-camera XR workflows using frame interleaving or Ghostframe.

NODOS gives Reality 5 a dedicated processing layer for live video and compositing, creating a clearer and more scalable production pipeline for AR, virtual studios, XR, videowalls, and on-air graphics.
