Grok Imagine Video 1.5

Generate 1–15 second videos from text, one first frame, or up to seven image references at 480p, 720p, or 1080p. 1080p accepts at most one image. ### Supported modes | Mode | Required input | Rules | | --- | --- | --- | | Text to video | `model`, `prompt` | Omit `images` and `reference_images`. | | First frame | `model`, `prompt`, `images` | Provide one image URL and omit `aspect_ratio`. | | Reference images | `model`, `prompt`, `reference_images` | Provide 1–7 URLs; 1080p accepts at most one image. | **Async flow:** Create the task, save `data.id`, then [poll the Task](/quick-guide#get-task-status) with `GET /v1/tasks/{task_id}`. On `succeeded`, read `data.output.media`. On `failed`, read `data.error_code` and `data.error_message`, then follow the [error and retry policy](/quick-guide#errors-and-retry-policy). **Using a local file?** [upload a local input](/quick-guide#upload-an-input-file) first and pass the returned `data.url`.
