jongranskog · x · 2026-11-02

The author pushed Runway's App Studio further, asking it to build "Stagecraft" — a 3D editor with path tracing, agentic scene building, and Seedance 2.5 rendering. The screenshots show an object-by-object table-and-chair scene editor with keyframe animation and prompt-driven camera moves ("slow cinematic push-in"), used to render a silly frog video. A glimpse of AI app builders extending into generative 3D scene-to-video pipelines.
