Cinematic motion - the woman looks up out into the sunlight filtering into the room.
Low angle wide shot of a massive, monolithic dark gray brutalist pyramid temple sitting in an infinite desert storm. Dust blowing across the frame. Massive, sleek matte-black spherical space vessels descending slowly from the foggy sky. Cinematic lighting, dramatic shadows, minimal aesthetic, high contrast, atmospheric fog, Denis Villeneuve style, hyper-realistic, slow camera tilt up, 4k.
A premium cinematic product launch photo for a futuristic iPhone 17 Pro Max, floating in a dark glossy studio environment with soft reflections and dramatic rim lighting. Show a vibrant high-resolution wave wallpaper with slight movement on the display, with crisp glass reflections, thin bezels, and a polished titanium frame. The camera pushes in slightly as the phone turns, emphasizing the screen brightness and premium materials. Then make a clean, high-end editorial cut: the phone flips smoothly in slow motion, revealing the back. The lighting shifts to highlight the rear design, focusing on the large camera system with precision-machined lenses, subtle lens reflections, and realistic depth. End on a hero shot of the camera module, with elegant Apple-style launch energy, minimal background, cinematic lighting, ultra-realistic materials, shallow depth of field, 4K, luxury tech commercial, smooth motion, no text, no hands, no extra objects.
Give some motion to the space ship launching
The character turns toward the camera and looks up and behind him rain starts to fall. Crisp rainfall and fishing town ambience

Grok Imagine Video 1.5 API FAQ
What can Grok Imagine Video 1.5 do?
It generates 1 to 15 second videos from text or from a first-frame image, with synchronized audio (dialogue, lip-sync, sound effects and ambience) generated in the same pass.
Which resolutions and aspect ratios are supported?
480p, 720p and 1080p, with 16:9, 4:3, 3:2, 1:1, 2:3, 3:4 and 9:16. Image-to-video follows the source image's framing.
How should I write prompts?
Describe the motion, not just the picture: who moves, how the camera moves and what changes over time. Add an audio line for sounds. Clips of 5 to 8 seconds tend to be the most stable.
How long does a generation take?
Usually about a minute, longer at 1080p or under load. Requests are asynchronous: create a generation, then poll it until it succeeds.
How is it billed on 01router?
Text-to-video is billed per output second at the chosen resolution; image-to-video prices depend on the provider. See the pricing table. Failed generations are refunded.
