Kling 4.0 FAQ
Learn about inputs, duration, audio and batch generation.
1
How do I create an image-to-video clip with Kling 4.0?
Upload a first-frame image, then optionally set a last frame and up to 8 middle keyframes to control visual moments in the video.
2
Does Kling 4.0 support text-to-video generation?
Yes. Describe the scene, action and camera without uploading an image. Choose a duration from 3 to 30 seconds and 720p or 1080p output.
3
How do keyframes differ from reference generation?
Keyframes define moments on the timeline: a first frame, a last frame and up to 8 middle keyframes. Reference generation uses images, videos or audio to guide subjects, motion and style. The modes cannot be combined in one request.
4
Which durations and resolutions does Kling 4.0 support?
Generate 3–30 seconds per clip in one-second steps, at either 720p or 1080p.
5
Can I turn off audio in Kling 4.0 videos?
There is no audio-off option. With reference video, choose regenerated sound or keep the first video's original audio.
6
How many Kling 4.0 videos can I generate at once?
Choose 1–4 videos. Each is submitted as a separate request, and the combined credit quote appears before generation.
