Kling 4.0

Direct the shot, from first frame to last.

Turn a prompt into a video, bring your own references, or guide the sequence with keyframes. Kling 4.0 gives you room for a longer scene and control over its format.

Three ways to shape your scene

Start with a prompt

Describe the subject, setting, action and camera movement. Choose a duration and frame format to suit a short clip or a longer sequence.

Bring visual references

Add reference images or a video to guide the scene. Explain in your prompt which details, motion or composition you want to carry into the result.

Guide the key moments

Use first and last frame images to guide the progression. Choose keyframes or reference media for a generation; the two modes cannot be combined.

From an idea to your first video

Open the playground with Kling 4.0 already selected. Start with a focused scene, then adjust your prompt and inputs for the next version.

Kling 4.0 questions

Which durations and resolutions can I use?

This site offers 3–30 second videos in 720p or 1080p. Aspect ratios are 21:9, 16:9, 1:1, 9:16 and Auto. The playground shows the settings available for your selected inputs.

Can I combine reference media and keyframes?

Use one mode per generation. You can guide a video with reference media, or use first and last frame images. Remove the inputs from one mode before switching to the other.

How many credits does a video cost?

Credits depend on the output duration, resolution and whether a reference video is included. Check the estimate shown in the playground before submitting, and visit pricing for credit packages.
