Grok Imagine Video 1.5 Preview
Grok Imagine Video 1.5 Preview is xAI's newer preview image-to-video model. It is positioned above the earlier Grok Imagine Video release with higher per-second pricing, supports durations up to 15 seconds, and generates 480p or 720p video from a single still-image starting frame for cinematic clips, animated visuals, and prompt-guided short-form video creation.

"positivePrompt": "Animate the initial still into a refined macro science-film shot: the amber mantis slowly flexes its forelegs and turns its faceted head by a few degrees, inner inclusions refracting pale blue UV light. The camera glides forward with gentle parallax across catalog tags and stainless pins, focus breathing from the nearest claw to the eyes, dust particles drifting through the light beams. Keep the sealed specimen chamber stable, realistic, and highly detailed, with subtle reflections and no sudden cuts.",

"positivePrompt": "Cinematic 15-second image-to-video from the supplied first frame: the monumental white origami whale begins to glide through the sunlit railway concourse as if buoyant in air, paper seams gently flexing and catching golden light. Folded paper birds swirl upward in coordinated spirals, travelers below shift their gaze and step back with subtle awe, dust motes drift through bright beams, reflections slide across the polished stone floor. Slow forward dolly with slight upward tilt, natural parallax, elegant motion, crisp paper texture, warm nostalgic color grade, realistic depth of field, smooth filmic pacing.",

"positivePrompt": "Animate the giant enamel-and-brass fox automaton from the first frame as it slowly lifts one paw and steps forward across the reflective ice. Its segmented tail plates articulate in a smooth wave, small gears turning under translucent enamel panels. Tiny expedition figures look up and scatter gently for scale. Frost crystals drift past the lens, aurora ribbons ripple subtly across the sky, and reflections stretch across the frozen surface. Cinematic slow dolly-in with slight left-to-right parallax, stable composition, realistic physics, refined mechanical motion, epic polar atmosphere.",
