4DV.ai
Volumetric video built on 4D Gaussian Splatting: capture with a camera array, then orbit, zoom, and change angle in a browser during playback, with splats tracked continuously across time rather than reconstructed per frame. The NAB 2026 demo cut a 60-camera OBSBOT rig's ~8.4Gbps raw input to a 30–60Mbps stream. Capture-then-process; no live streaming yet.
