About
A joint audio-video model that accurately follows complex instructions.
Example Output
"A young astronaut in a worn spacesuit sits in the dim cockpit of a spacecraft. The helmet visor is covered with fog and scratches, and the control panel flickers with orange-yellow lights, creating a tense and lonely atmosphere. The video begins with this static opening frame. The camera then rapidly zooms into the astronaut’s face before cutting to the exterior, revealing the spacecraft racing through a blizzard-like storm of cosmic debris. Sci-fi thriller style. Background music: low electronic synthesizers paired with rapidly swelling strings to build suspense. Sound effects: urgent engine hums and howling space-storm noise. Dialogue: "In the void of space, one wrong move..." followed by a brief silence, ending with: "Mayday... systems failing.""
