About Kling v3 Omni

Combine up to 7 reference images, or first and last frames, into one Kling VIDEO 3.0 Omni clip at 720p or 1080p.

Why choose Kling v3 Omni?

Kling v3 Omni is Kuaishou's Kling VIDEO 3.0 Omni model. Kling positions Omni around references: its guide describes combining up to 7 images or elements, building consistent characters, and generating up to 15 seconds with native audio.

Wizzx exposes the image side of that workflow. Besides text-to-video and first/last-frame video, kling-v3-omni accepts 1–7 reference images for subjects, scenes, or styles, and you can point to each one in the prompt.

Wizzx controlCurrent behavior

Best-fit workflows

  • Character in a new place: put a character in one reference and a location in another, then describe how they meet.
  • Product storytelling: keep a product, a model, and a set consistent across one clip.
  • Style transfer: add a style reference and describe the motion you want in that look.

Prompting approach

Number references in the order you upload them and name their role, for example "the jacket from <<<image_2>>>". If the prompt cites no image, <<<image_1>>> is added automatically, so put the main subject first. Keep one clear action per clip and describe the camera separately.

Wizzx scope

Wizzx returns one video per request without a watermark. Resolution and audio select the per-second rate, duration sets the total, and reference images are free; the live amounts come from the backend catalog. Reference videos, voice binding, multi-shot storyboards, element libraries, and 4K are not exposed for this model.

Integrate the Kling 3.0 Omni API

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 Kling 3.0 Omni API 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.
