Kling 4.0
Give your scene more time to unfold. Kling 4.0 brings up to 30-second generation, 10 keyframes, and output up to 4K to your next film, product story, or campaign.
Why serious creatives should consider using Kling 4.0
30 seconds to tell the whole scene
Now generate up to 30 seconds which is double the output from Kling 3.0. Carry dialogue or a product demo from setup to payoff in one pass.
Direct the moments between the first and last frame
Use up to 10 keyframes to plan the turning points. Establish the wide shot, move into the reveal, and finish on the composition you want your audience to remember.
Build the scene with up to 15 references
Expanded Omni Reference brings up to 15 assets into one generation, giving you more room for character views, product details, and motion references.
Improved lip sync for more believable dialogue
Improved lip sync makes close-ups and conversations feel more natural, while native stereo audio brings depth to voices and the surrounding scene.
Richer color and detail with 10-bit HDR
Create richer colors and smoother tonal transitions with 10-bit HDR at 1080p and 4K, preserving detail in bright highlights and deep shadows.
Rework the take
Keep developing an idea after its first generation. Change the background, refine an expression, or try a different visual style. Shape the take around your creative direction as the scene evolves.
Coming soonHow to use Kling 4.0 with invideo agents
Bring your references, describe the scene, and work with the agent from the first prompt to the final take.
Attach your references and brief the agent
Upload character images, product shots, or visual references. Explain what you want to create and the details that need to stay consistent.
Direct the scene
Describe the action, camera movement, dialogue, and mood. You can also define what happens in specific segments of the video—for example, “From 0:05 to 0:12, the camera slowly zooms in as the character speaks.” Ask the agent to use Kling 4.0 and turn your direction into a generation prompt.
Generate your video
Approve the prompt and let the agent generate your scene with the references and direction you supplied.
Review and edit the take
Watch the result and tell the agent what to change. Refine the performance, timing, or visual details, then add the selected take to your edit.
Impeccable character consistency with Kling 4.0
Build a consistent character reference pack
Choose clear views of your character with the same hairstyle, clothing, and defining features. Pair this pack with a fixed name and description, such as “Maya, with a chin-length black bob and a red denim jacket”. Reuse both throughout your prompts to keep their appearance consistent across shots.
Map the scene with keyframes
Place your character into the key moments: entering the room, turning toward the camera, and landing in the final close-up. Use those frames to guide the sequence.
Specify what changes and what stays
Describe the new action or camera angle, then name the details to preserve: "Maya turns toward the window. Keep her face, hairstyle, and red denim jacket unchanged from the reference."
