Provide one external image URL as a reference for video generation (only one image is supported). This is one of two image input options — you can either upload an external image or specify a task_id + index from a Grok-generated image below. Do not provide both image_urls and task_id at the same time.In your prompt, reference an uploaded image by typing @image(n) followed by a space (for example: @image1 a sunset over the ocean).
Enter the task_id of an image previously generated with the Grok model on Kie. Use it together with the index below to select a specific image from that generation. When using this method, do not provide image_urls. Unlike external images, this method supports Spicy mode.
When using a task_id, specify which image to use (Grok generates 6 images per task). This parameter only works with task_id and is ignored if image_urls is used(0-based).
The text prompt describing the desired video motion
Note: When generating videos using external image inputs, Spicy mode is not supported and will automatically switch to Normal.
