What is the Grok Imagine Video 1.5 API?

The Grok Imagine Video 1.5 API is the video side of xAI's Grok Imagine API, available through APIMart. It supports text-to-video from a prompt and Grok image to video from reference images, generating high-quality videos with remarkable visual fidelity.

What parameters does Grok Imagine Video 1.5 accept?

Standard generation requests need model and prompt. The official grok-imagine-video-1.5 supports 1–15 seconds, 480p/720p/1080p and seven aspect_ratio values. The Ext model grok-imagine-1.5-video-ext supports 6–15 seconds, 480p/720p and five size values. Optional settings differ by model; check the docs for supported values.

How does Grok image to video work with the Grok Imagine Video 1.5 API?

Send your prompt together with one or more public HTTPS image URLs in the image_urls field. The Grok Imagine Video 1.5 API animates the still image according to your prompt. Like text-to-video, the request runs as an asynchronous task: you receive a task ID and poll it until the video is ready. Ext accepts 1–7 reference image URLs for standard generation. It also animates Grok image assets using image_id with quick_animate, spicy or add_prompt. Only add_prompt requires a prompt. Asset mode supports 6–15 seconds at 480p/720p, follows the source image ratio and does not use image_urls or aspect-ratio fields.

How long does video generation take?

Depending on server load and content complexity, video generation typically takes 30-120 seconds to complete.
