If a clip runs past 15 seconds, or the move from the first frame to the last needs more than 5 seconds, use Kling 4.0: Kling 3.0 can’t make it. For anything shorter, Kling 3.0 is still a good model and costs less per second: 14 credits at Std against 29 for Kling 4.0 at 720p. Kling 4.0 Flash sits in between at 17.
How this page compares: specs and prices come from the generator’s own code, so they match what you are charged. What each model does better comes from Kuaishou’s Kling 4.0 notes, and we say so wherever we use them. We haven’t scored the models; the test prompts above let you judge with your own eyes.

Kling 3.0’s longest clip is 15 seconds. That covers most social clips, but a slow reveal, a full product turn or a walk through a space often needs more, and joining two clips leaves a seam: the light, the face or the camera height shifts at the cut.
Kling 4.0 makes up to 30 seconds in one generation, so the whole move keeps one look. A 30-second clip costs 870 credits at 720p and 1,290 at 1080p.
Both models can start on one picture, end on another and fill in the motion between them. On Imgveo, Kling 3.0 keeps that transition to 5 seconds. Kling 4.0 takes it up to 30.
That matters for before-and-after reveals, a day-to-night change, or a product that has to land in an exact pose. In a few seconds the change feels rushed; with more time the model can move the camera and the subject at a natural pace.
Tip: give both frames the same aspect ratio. Kling 4.0 takes the clip’s ratio from the first frame.
Every number below comes from the same code that charges you, so it changes when our prices do. Failed clips are refunded.
| Clip | Kling 4.0 · 720p | Kling 4.0 · 1080p | Kling 3.0 · Std | Kling 3.0 · Pro | Kling 4.0 Flash |
|---|---|---|---|---|---|
| 5 seconds | 145 | 215 | 70 (100) | 90 (135) | 85 |
| 10 seconds | 290 | 430 | 140 (200) | 180 (270) | 170 |
| 15 seconds | 435 | 645 | 210 (300) | 270 (405) | 255 |

720p or 1080p, up to 30 seconds, in all three modes including first and last frame. The one for finals.
