What it does
Generates persistent 3D worlds from text, images, video, 360° panoramas or blocked-out 3D layouts. Exports Gaussian splats and GLB meshes, and records camera flythrough videos.
AI video, image and audio generation (Runway Gen-4.5 plus third-party models), usable for trailer shots, teasers and marketing material.
Verdict
For blocking out explorable environments or flythrough shots; exports go to Unity/Unreal via Gaussian-splat plugins, and commercial rights are listed on Pro.
For generating trailer and teaser shots; the terms don't restrict commercial use of outputs, but Runway may train on your inputs and outputs.
