| Parameter | Type | Default | Range / values | Description |
|---|---|---|---|---|
| prompt | string | - | - | Text prompt describing the video (text-to-video) or the motion to apply to the source image (image-to-video). |
| model_tier | enum | standard | standard, pro, 4k | standard: 720p, fastest. pro: 1080p, higher fidelity. 4k: 3840x2160, highest fidelity and cost. |
| aspect_ratio | enum | 16:9 | 16:9, 9:16, 1:1 | Aspect ratio for text-to-video. Image-to-video follows the source image. |
| duration | number | 5 | 3 to 15 | Video length in seconds (3 to 15). |
| sound | boolean | true | - | Generate native audio with the video. Standard and pro bill a higher rate with sound on; 4k includes audio. |
| negative_prompt | string | - | - | What to avoid in the output. |
| image | string | - | - | Source image URL for image-to-video. One image animates from that frame; two set the first and last frame. |
Model tiers: standard renders 720p, pro renders 1080p, 4k renders 3840x2160. Durations run 3 to 15 seconds. Native audio is on by default; turning Sound off bills the lower rate on standard and pro, while 4K includes audio at one flat rate. Image-to-video accepts one or two images (first and last frame) and follows the source image size.
On EmpirioLabs, Kling V3 is billed pay as you go: Standard T2V/I2V $0.168 per second; Standard T2V/I2V Sound $0.252 per second; Pro T2V/I2V $0.224 per second. The live rate card on this page always matches what the API charges.
