Kling 4.0 Prompt Guide: Direct Better Video Scenes

A useful video prompt gives the generator a subject, action, setting and camera plan. Select Kling 4.0 in the homepage generator, then choose 3–30 seconds and 720p or 1080p.

Build a prompt in four parts

1. Subject: describe the person, product or object and the details that matter.
2. Action: specify one clear motion and how it develops within the chosen duration.
3. Camera: set framing, movement and point of view.
4. Look and sound: add lighting, color, ambience and sound cues. Kling 4.0 includes stereo audio; this integration has no separate audio-off control.

For image-to-video, start with your own first-frame image. A prompt is optional, but motion directions can clarify your intent. Add up to eight middle frames in order and an optional last frame, with ten frame images total. These are frame controls, not arbitrary image references or voice/video uploads. Inputs do not guarantee perfect character or product consistency.

Example prompts

These are writing examples, not prompts paired with verified published Kling 4.0 results.

Portrait, 5 seconds: “A ceramic artist slowly turns a glazed bowl under soft window light. One close-up dolly, shallow depth of field, quiet workshop ambience.”

Product, 5 seconds: “A compact camera rotates on a dark plinth while a narrow rim light reveals its metal texture. One continuous orbit, clean background, soft mechanical ambience, no text overlays.”

Vertical clip, 5 seconds: “A cyclist stops beside a flower market at sunrise. Handheld eye-level camera follows the turn, warm natural light, street ambience, 9:16 composition.”

Match the selected settings

Keep the action within 3–30 seconds. Choose 9:16 for vertical framing or one of the other supported ratios (16:9, 1:1, 21:9). Video extension is available for an existing source clip; Flash and Kling 4.0 4K are not integrated. For keyframes, keep the subject and composition compatible between images, then check the actual motion and sound in the output.

Sign in and review the paid-credit quote before every run. The minimum is 85 paid credits for 720p, 3 seconds; daily free rewards cannot fund Kling 4.0. Change one instruction at a time when iterating. Gallery clips are creative references with unverified models. See the complete guide for inputs and credit rules.
