What you can build
Real workflows powered by this model.
Animate a still with the Grok Imagine 1.0 Video API
Pass one reference image and a motion prompt. The Grok Imagine 1.0 Video API returns a 6 to 30 second clip from the same endpoint as your text-to-video calls — no model swap. The output aspect ratio matches the source image automatically.
Generate a clipCompose richer scenes from up to seven references
Send up to seven reference images alongside a prompt and the Grok Imagine 1.0 Video API fuses subject, style, and props into a brand-new motion shot — character reskins, product spots, multi-style social posts, all in one request.
Text-to-video with a flat per-second price
Describe the scene, pick an aspect ratio, and the Grok Imagine 1.0 Video API returns a clip with coherent motion and lighting. 480p and 720p share the same per-second rate, so quality choice never surprises you on the bill.

Why reAPI
One endpoint, two modes
The Grok Imagine 1.0 Video API picks its mode from the count of image_urls you send. Zero gives you text-to-video, 1 to 7 gives image-to-video — all on the same /api/v1/videos/generations call, with the same authentication and the same task polling pattern.
Flat per-second price across qualities
The Grok Imagine 1.0 Video API charges the same per-second rate at 480p and 720p — pick HD whenever you need it without re-doing the math. Bill scales linearly with duration, and failed jobs refund automatically.
Up to seven reference images
Supply between one and seven references on a single Grok Imagine 1.0 Video API request. Use the first as a starting frame, the rest as style and subject guidance — no separate stitching or fine-tune step required.
