CREATIVE POSSIBILITIES
From product reveal to plot twist.
Prepare briefs for cinematic campaigns, short stories, dialogue scenes and stylized animation. Start with a focused shot, then build the sequence around it.
PRODUCT / CAMERA DIRECTION
Make the reveal feel real.
A brushed silver camera rests on a dark stone plinth. Begin on the textured shutter button, then track slowly around the camera as a soft strip of light crosses the metal. Preserve the product shape and fine surface detail. One continuous shot, restrained cinematic lighting, quiet studio ambience, no added text.
Prepare a sharp product reference. Use one camera move and check small details before expanding the scene.
STORY / KEYFRAME DIRECTION
Give every beat a purpose.
Use the supplied keyframes as the visual beats of a continuous scene. A traveler steps into a quiet station, notices a familiar face across the platform, then smiles in recognition. Preserve the character's appearance between beats. A slow tracking camera, warm evening light, natural footsteps and distant station ambience.
Prepare opening, middle and closing images. Keep wardrobe, lighting and character identity consistent across frames.
PERFORMANCE / NATIVE SOUND
Let the voice carry the scene.
A musician sits beside a studio microphone, looks toward the camera, and says in a relaxed British English voice: 'Let's take it from the top.' A small smile follows. A gentle push-in, natural skin texture, soft room ambience, synchronized dialogue, no music or on-screen captions.
Name the speaker, language and exact dialogue. Listen to the audio and review mouth movement alongside the picture.
YOUR FIRST KLING 4.0 BRIEF
Plan now. Create at launch.
Build a clear brief and collect the references you want to use. When Kling 4.0 arrives on Unify, check the available settings and generation quote before rendering.
Define the shot
Name the subject, action, camera, light and sound. Use timing cues when the scene contains more than one visual beat.
Prepare your references
Choose images, motion clips and keyframes that agree on identity and style. State which detail each reference should guide.
Review and refine
At launch, start with a short draft. Check faces, hands, lettering and audio, then change one instruction at a time.
KLING 4.0 4K VIDEO
A closer look at cinematic detail.
Kling 4.0 lists 4K output for the standard model, bringing more detail to characters, lighting and textures. Build scenes for cinematic campaigns, product storytelling and a larger screen.
Kling AI also announces 10-bit HDR at 1080p and 4K, coming soon, for richer color and smoother transitions between highlights and shadows. Watch the provider's visual-quality demonstration.
REFERENCE-BASED CREATIVE DIRECTION
Kling 4.0 motion control.
Bring the movement you have in mind. Kling 4.0 motion control uses video references to guide character performances, actions, camera movement and narrative pacing.
Use a motion reference to communicate a dance, a sports action or a camera move, then pair it with the character and visual direction for your scene. Give timing, body movement and rhythm a clear role in the brief.
- Guide character action and expressive performance.
- Carry camera movement and pacing from a reference.

How is Kling 4.0 Flash different?

The release lists up to 15 reference items combined across images, videos, voice references and elements.
