How to Use Kling 3.0 4K Text-to-Video

  1. Prepare Your Input

    • Write a detailed prompt covering subject, action, environment, lighting, and camera movement.
    • Choose an aspect_ratio (16:9, 9:16, or 1:1) — resolution will be 3840×2160, 2160×3840, or 2160×2160 respectively.
    • Set duration between 3 and 15 seconds and toggle generate_audio as needed.

  2. Submit Your Request

    • Send a POST to /kling-v3.0-4k-text-to-video with your structured payload.
    • Poll the prediction endpoint for completion — 4K renders take longer than std or pro.

  3. Interpret the Results

    • The output JSON includes a video URL pointing to the generated 4K clip.
    • Refine your prompt if the motion, composition, or timing needs adjustment.

Common Questions

Frequently asked

What does the 4K tier output?

3840×2160 for 16:9, 2160×3840 for 9:16, and 2160×2160 for 1:1.

Is it significantly slower than Pro mode?

Yes. 4K rendering takes longer and consumes more credits than Pro because of the higher pixel count. Plan for longer processing times.

Do all Pro features carry over?

Duration (3–15s), aspect ratio selection, and audio generation all work identically. Motion quality matches Pro — only resolution changes.

When should I pick 4K over Pro?

Choose 4K when the output will be played on large screens, composited into a 4K timeline, or cropped. Otherwise Pro at 1080p is usually sufficient.
