How long can a Kling 4.0 video be?
+
Any length from 3 to 30 seconds, chosen by the second.
Which generation modes and references are supported?
+
Text to video, image to video with a first frame and an optional last frame, and reference to video with up to 10 images and 5 videos. Reference videos need to be at least 3 seconds each and 30 seconds in total.
Which resolutions and aspect ratios are supported?
+

How are credits calculated?
+
Credits depend on duration and resolution. When you add reference videos, a lower per-second rate applies, and the billed seconds include the output plus the longer of the reference videos or the output. The Generate button shows the exact credits before you start, and credits for failed generations are returned automatically.
How is Kling 4.0 different from Kling 3.0?
+
On AI Video Generator, Kling 4.0 supports up to 30 seconds (Kling 3.0 supports 15), reference to video with images and videos, and the 21:9 aspect ratio. Kling 3.0 still offers motion control and a sound on/off option. You can switch between them in the same generator.
