Length, resolution and aspect ratio
| Model | Presets | Range | Resolution |
|---|---|---|---|
| Kling 3.0 | 5 · 10 · 15 s | 3–15 s | 4K · 1080p · 720p |
| Kling 3.0 Turbo | 5 · 10 · 15 s | 3–15 s | 1080p · 720p |
| Kling 3.0 Omni | 5 · 10 · 15 s | 3–15 s | 4K · 1080p · 720p |
Aspect ratio is 16:9 · 9:16 · 1:1. When you start from an image the ratio is not sent at all — the output follows the ratio of the input image.
Resolution maps to Kling's mode — 720p is std, 1080p is pro, 4K is 4k. The resolution shown, the resolution generated and the amount deducted all read the same value.
Audio comes with the video
Kling 3.0 is submitted with native audio on, so speech and sound effects are generated alongside the picture. That is already covered by the per-second rate — nothing is added on top.
What you can attach

| Kling 3.0 | Yes | Yes | — |
| Kling 3.0 Turbo | Yes | — | — |
| Kling 3.0 Omni | Yes | Yes | 7 including first and end frames |
Kling 3.0 and Turbo do not pass reference images to the model. Images and videos you attach are analysed first and the description is prepended to the prompt; you can attach up to 14 images and 1 video, and the analysis itself costs credits, shown on the generate button. Kling 3.0 Omni is the one that hands reference images straight to the model.
Negative prompts take up to 2,500 characters The Omni prompt body takes up to 3,072
How billing works
Video is billed per second of output and only for what is actually generated. There is no monthly subscription, and credits stay valid for one year from the date of purchase. Failed generations are refunded.

How do reference images work?
Kling 3.0 and Turbo take frames rather than reference images: 3.0 accepts a first and an end frame, Turbo accepts a first frame only. Images attached to those two do not reach the model directly — they are analysed and the description is prepended to the prompt. Kling 3.0 Omni is the one that passes reference images straight through, up to 7 including the first and end frames.
