About Kling v3

Generate 3-15 second Kling VIDEO 3.0 clips from text or first and last frames at 720p or 1080p, with optional native audio.

Why choose Kling v3?

Kling v3 is Kuaishou's Kling VIDEO 3.0 model. Kling describes it as a model for text-to-video, image-to-video, and start-and-end-frame video, with native audio that can include dialogue in several languages and flexible durations from 3 to 15 seconds.

In Wizzx, kling-v3 is a separate model key from the older Kling AI variants. Use it when you want a single clip that starts, and optionally ends, on frames you control.

Wizzx controlCurrent behavior
PromptRequired, up to 2,500 characters
ModeText to video, or image to video with 1 (first) or 2 (first + last) frames
Resolution720p (standard mode, default) or 1080p (professional mode)
DurationAny whole number from 3 to 15 seconds, default 5
AudioOff by default; turn on native audio at a higher per-second rate
Aspect ratio16:9, 9:16, or 1:1; a first frame's ratio may take precedence
Negative promptOptional, up to 2,500 characters

Best-fit workflows

  • Shot bridging: give a first and last frame to animate a controlled transition between two stills.
  • Product and character motion: start from an approved key visual so the look stays on brief.
  • Talking or ambient scenes: enable audio when dialogue, ambience, or effects should come with the picture.

Prompting approach

Describe the subject, the action, and the camera move in one or two sentences, then add lighting and mood. With frames, describe what happens between them rather than repeating what the images already show. Use the negative prompt for recurring artifacts such as blur or distorted hands.

Wizzx scope

Wizzx returns one video per request without a watermark. Resolution and audio select the per-second rate, and duration sets the total; the live amounts come from the backend catalog. Kling's multi-shot storyboards, element references, and 4K output are not exposed for this model. Use Kling v3 Omni when you need reference images.

Integrate the Kling 3.0 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 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.
