About Grok Imagine Video 1.5

Generate 6-15 second xAI Grok Imagine Video 1.5 clips from text or up to 7 reference images at 480p or 720p.

Why choose Grok Imagine Video 1.5?

Grok Imagine Video 1.5 is xAI's video generation model, released in June 2026. xAI calls it its best image-to-video model and says sound effects, ambience, and dialogue are generated in the same pass as the picture.

In Wizzx, you can start from a prompt alone or add up to seven reference images, and choose 480p for quick drafts or 720p for sharper output.

Best-fit workflows

  • Bring a still to life: animate a photo, illustration, or product shot with natural motion.
  • Consistent subjects: add several references of the same subject or setting to keep it recognizable.
  • Short social clips: 6-second 720p output fits looping and story formats.

Prompting approach

Describe what should move and how the camera behaves, then add atmosphere and sound cues. With references, describe how they relate instead of listing them. Keep a clip to one main action; longer durations work best when the action naturally unfolds over time.

Wizzx scope

Wizzx returns one video per request. Resolution selects the per-second rate and duration sets the total; reference images are free, and the live amounts come from the backend catalog. xAI also offers higher resolutions, audio and voice references, and video editing for its Imagine family; Wizzx currently exposes only the text and image-reference modes above at 480p and 720p.

Integrate the Grok Imagine API (Video 1.5)

Every request is asynchronous: submit the task, keep the task ID, then poll for the result. The body below uses the model's default settings.

  1. 1

    Get a Grok Imagine API (Video 1.5) key

    Sign in and create a key in the dashboard. Set WIZZX_API_KEY in your server environment; never expose it in browser code.

  2. 2

    Submit a task

    Send a POST request to the model endpoint. A successful submission returns data.task_id; keep that ID before polling. Submission is not generation completion.

  3. 3

    Retrieve the result

    Replace YOUR_TASK_ID with the returned ID and query /api/v1/task/status. Wait for SUCCEEDED and read the output URLs. Stop on FAILED or REVIEW_REQUIRED; do not automatically resubmit an uncertain task.
