The October 27, 2026 announcement describes a scene you start and steer, with keyboard or mouse, camera controls, and text that can change the weather or add a person or object. Music, noise, and dialogue are described in the same simulation. DeepMind says Gemini Omni anchors how it looks.
DeepMind presents Genie 4 as early research: a few minutes of interaction rather than a long production, with drift as a session runs, and with locations, legible text, and real-time audio still unfinished. Genie 4 video and audio are said to carry SynthID. That describes Google’s output, not a switch here. Movelume has not run a session, so this page does not add controls, export formats, or a walkthrough.
