3D videos: a 3D world for your topic

A 3D video is a short clip (30–60 seconds) in a real three-dimensional world: a city with cars, a kitchen, a room, a forest camp. A host character walks around the scene, objects appear and move, coloured zones show “right / dangerous”, 3D captions and numbers hover above the scene. The camera automatically shows the place where the action happens. How to make one: “Create video” → “3D video” (or the “3D videos” section in the menu). Choose a world, write a topic — for example “who goes first at an uncontrolled intersection” or “how to put out a campfire safely” — the language, duration (≈30, 45, 60 or 90 seconds — the AI writes a script of matching length), format (vertical 9:16 or horizontal 16:9), voice and music. The rest is automatic: the AI director writes a voice-over for the chosen duration and stages the scene using what exists in the world; a voice narrates it; a GPU is rented for your video and Blender renders the 3D world; then sound effects (engine, brakes, a whoosh on captions), music and subtitles are added. Usually 15–20 minutes. Cost: GPU rendering is charged to the AI balance at actual cost — about 1–3 kr per video, plus the voice-over. A balance of at least 5 kr is required. A finished video can be downloaded, “Repeated with the same settings” (new text and scene on the same topic) or “Redone” with another topic. With the same topic only the video is rebuilt, and the voice-over is not charged again.
