Input

Prompt*

Reference Image 1 as identity lock. Create a gritty, ultrarealistic live-action 16:9 film montage, 9 shots, 0.2 seconds each, shot on Arri Alexa with 35mm anamorphic lenses. Use the exact same real photographed woman in every shot (mid-20s, focused eyes, short asymmetrical hair, identical face, body and silhouette throughout). Real skin texture, natural imperfections, realistic hair movement. No CGI, no AI look, no clones, no doubles, no morphing, no face changes. Practical stunts and practical effects only. Each shot is a different movie genre with different locations, costumes, lighting and framing, but always the same actress. Action highway chase in a sports car: "Let's go!" Documentary thriller pushing through a rainy protest crowd: "Keep filming." Romantic thriller close-up in blue emergency light: "Trust me." Spy film ballroom dance stealing a keycard: "Got it!" Sports drama sprinting onto a stadium field: "We're going all the way!" Horror film backing through a flashlight-lit farmhouse hallway: "Creepy." Biopic music performance singing into a microphone: "Baby, I'm yours!" Love film under fireworks reassuring a male guitarist: "Happy Fourth!" Adventure film on a city observation deck, wind in her hair: "I'm ready for my next role!" One continuous fast heroic montage score, hard cuts only, every shot looking like a different real movie while clearly featuring the exact same actress.

What is the Grok Imagine Video 1.5 API?

Grok Imagine Video 1.5 is xAI's image-to-video model: send exactly one reference image and it animates that frame into a clip with natively generated, synchronized audio. Clips run 1 to 15 seconds at 480p or 720p, and an optional prompt of up to 4,096 characters directs the motion, camera, dialogue and sound. reAPI serves two channels — Official (prompt required, 6 to 15 seconds, three aspect ratios, audio toggle) and Beta (optional prompt, auto plus seven ratios) — each billed per second at its own 480p / 720p rate.
