Read the comparisonWhat is Kling 4.0?
Kling 4.0 is Kuaishou's newest video generation model. It makes clips of 3 to 30 seconds at 720p or 1080p, in 16:9, 9:16, 1:1 or 21:9, from a text prompt or a start and end frame, and every clip comes with a stereo soundtrack: the effects, ambience, music and dialogue written in the prompt. On APImage it costs 131 credits per 5 seconds at 720p and 196 at 1080p, sound included, up to 1,175 credits for a full 30 seconds at 1080p.
How much does Kling 4.0 cost on APImage?
131 credits per 5 seconds at 720p and 196 at 1080p, sound included. A full 30 seconds is 785 at 720p or 1,175 at 1080p.
How long can a Kling 4.0 clip be?
Any length from 3 to 30 seconds, in one second steps.
Can I turn the sound off?
No. Kling 4.0 always renders a stereo soundtrack, and the price includes it. For silent clips, Kling 3.0 is cheaper.
What changed from Kling 3.0?
Twice the length, 30 seconds against 15, a 21:9 frame and stereo sound in every clip. Kling 3.0 keeps a silent option, automatic multi-shot and a prompt adherence control, and costs less per second.
Which plan includes Kling 4.0?
Starter and up, out of the same credit pool as every other model on APImage.
How do I use it?
Open the video studio and pick Kling 4.0. Write the shot like a brief: the action, the camera move, what we hear and any lines spoken. Add a start frame, and an end frame if the move has a destination. With a start frame the clip takes the image's shape. Pick 720p or 1080p, set the length up to 30 seconds, and generate.
