Kling 4.0 lighthouse result

The published example shows an elevated approach toward the lighthouse. Check how the aerial viewpoint, moving waves, and recognizable building hold together throughout the shot.

Kling 3.0 lighthouse result

Compare this clip against the same camera instructions. Look at perspective, coastline detail, and water movement rather than choosing a winner from one attractive frame.

Shared lighthouse prompt

A cinematic aerial shot of a white lighthouse standing on a rugged rocky coastline during golden hour. Powerful ocean waves crash against the dark rocks, sending white sea spray into the air. The camera slowly moves forward toward the lighthouse while maintaining a smooth, stable aerial perspective. Natural ocean physics, realistic foam movement, consistent lighthouse architecture, atmospheric sunlight, detailed coastal landscape, cinematic realism, 16:9.

Watch for: Warm studio light moves across an amber bottle as the camera slowly pushes in. Watch the bottle silhouette and changing reflections throughout this five-second text-to-video example.

01

Longer scenes

Kling 4.0 supports 3–30 seconds in one generation. Give a longer take a clear beginning, action, and ending. Test the difficult movement briefly first; extra duration increases cost and creates more frames to inspect.

02

Motion and physical interaction

The model targets improved action and physical realism. When testing Kling 4.0, watch foot contact, object collisions, water, and body mechanics. A convincing opening frame does not establish believable motion throughout a sports or action sequence.

03

Omni Reference

The feature overview lists up to 15 combined assets: images, videos, subjects, and voice references. Individual caps include 10 images, five videos totaling 30 seconds, and seven subject Elements. These are shared limits, not quantities to add together.

04

Keyframes and camera direction

Kling 4.0 supports up to 10 keyframes. Anchor meaningful changes, then describe the movement between them. Choose a tracking shot, orbit, push-in, or pull-back with a clear purpose. Incompatible poses or viewpoints can make transitions harder.

05

Recreation and targeted edits

The broader feature set includes footage recreation and targeted changes. For a practical brief, identify what should change and what must stay recognizable. Our Kling 4.0 workspace offers reference guidance, without dedicated recreation or editing controls.

06

Audio and continuity

Kling 4.0 results can include sound here. Add MP3/WAV references for audio guidance, or retain video sound with Keep original video audio. These options cannot be combined. Saved Elements controls are absent. Listen for speech timing, unwanted sounds, and abrupt changes before combining clips in an edit.

Compare Kling 4.0 and 3.0 videos

Advertising and product concepts

Use clean product references and a controlled reveal. Kling 4.0 helps explore presentation ideas; inspect shape, reflections, and labels. Add exact promotional text in editing when spelling and brand accuracy matter.

Character scenes and storyboards

Use compatible references or keyframes to establish important moments. Check identity, hands, transitions, and scene geography. Split unrelated events into separate shots instead of forcing an entire story into one request.

Music videos and visual loops

Build a Kling 4.0 shot around a musical mood, recurring subject, or camera movement. Create short visual sequences, then align cuts and transitions with your track in editing.

Explainers and educational clips

Use Kling 4.0 to illustrate a process or introduce an idea with a focused scene. Keep each clip to one concept, verify visual details, and add accurate labels afterward.

Architecture and interior previews

Explore lighting, atmosphere, and camera paths through a proposed space with Kling 4.0. Use consistent room references to communicate a design direction, then review geometry and material details.
