Explore what's new
Create longer scenes, direct key moments, work with richer references, and refine existing footage. Explore how these capabilities give you more control from the first idea to the final video.
Longer storytelling
Kling 4.0 raises the maximum duration of a single generation from 15 seconds in Kling 3.0 to 30 seconds.
Use the extra time to establish a setting, show a character interaction, and reach a closing moment within one sequence.
From 15s to 30s
Multi-keyframe control
Place up to 10 keyframe images along a timeline to mark visual moments such as a character entrance, a change in composition, or a final close-up.
These checkpoints guide how the scene progresses while the model generates movement between them.
Up to 10 Keyframes
Omni Reference
Omni Reference lets you combine images, videos, subjects, and voice styles in one task—up to 15 reference assets overall, with separate limits for each input type.
Use a product image to guide its appearance and a video reference to guide action or pacing as you develop a new scene.

Precise video editing
Request targeted changes to an existing video, such as a character’s expression, the background, or camera movement, while guiding the model to preserve the rest of the shot. An editing task can include up to five clips, including one primary video, within a combined duration limit of 30 seconds.
Refine a shot you already like instead of rebuilding the sequence when one detail needs to change.

Motion & camera
Kling 4.0 improves stability during fast motion and complex camera work, including continuous action, tracking shots, and camera orbits.
Follow a subject through a busy street or move the camera around an action in one continuous shot.

Use dialogue, ambience, and music to support a character moment or set the mood of a product scene.

Creative applications
From social clips and product showcases to cinematic stories and performances, explore six types of videos you can create with Kling 4.0. Start with a prompt, image, or supported reference materials to bring your ideas to life.
Education
Show a process through visible stages, from setup to a finished result. Reference the instructor and equipment, then describe each action in the order viewers should see it.
Creative tip: Keep each step physically clear and verify details before publishing.

Storytelling
Use a starting frame, a middle moment, and an ending frame to map a character reunion. Keyframes guide the visual sequence while the prompt describes movement and dialogue.
Creative tip: Keep the characters and station layout consistent across all frames.
Last Train Reunion
Product marketing
Place a product in a lifestyle setting while keeping its shape and finish recognizable. Pair a clean product image with a setting reference and guide the camera toward the details that matter.
Creative tip: Describe the product features the camera should preserve.

Social content
Shape a vertical creator update with a consistent face, setting, and conversational delivery. Use an image for the creator, a second image for the room, and a voice reference for the speaker.
Creative tip: Keep the main action and spoken line short enough for a phone screen.
Everyday Creator Update
Advertising
Plan a short launch concept with a product reveal, movement, and a closing shot. Use product, location, and character references to give each beat a clear visual role.
Creative tip: Give the opening, action, and final frame distinct jobs.
City Bike Launch Teaser
Music & performance
Develop a performance scene around a singer, a room, and an original vocal reference. Guide the camera and describe how the music should support the visible action.
Creative tip: Review the finished performance for believable mouth motion and sound.

Choose Kling 4.0 when you need longer scenes, multiple planned visual moments, richer references, or more flexible video revisions.
Kling 3.0 remains useful for shorter scenes, multi-shot storytelling, and projects that don't require the additional timeline and reference controls.

Questions and answers
Find answers about choosing a generation mode, using voice references, improving video results, managing credits, and understanding your rights when creating with Kling 4.0.
No. kling-4.art is an independent AI video generation platform, not the official Kling AI website. It provides access to supported Kling 4.0 generation features, but available modes, resolutions, and settings may differ from those offered directly by Kling AI.
Kling 4.0 supports longer videos of up to 30 seconds, up to 10 keyframes, and more advanced reference controls. Kling 4.0 Flash is designed for faster, more frequent creation, with videos up to 20 seconds at 720p. Flash does not currently support first-and-last-frame or multiple-keyframe generation. Check the generator for available models and settings.
Choose Keyframes when you want to plan specific moments in a video, such as the opening, an important action, or the final shot. Choose Omni Reference when you want images, videos, or voice samples to guide characters, objects, movements, or visual styles. These are separate generation modes and cannot be combined in one task.
You can upload MP3 or WAV files as voice references in Omni Reference mode. Voice samples help guide a character’s voice but are not used as background music tracks. To request music, ambience, or sound effects, describe them in your video prompt. On kling-4.art, voice references currently require 720p output.
Describe the subject, actions, setting, and camera movement more precisely. When using references, explain which details should remain consistent. For scenes with several important moments, consider Keyframes to guide the sequence. Results may vary, and generating a revised version may use additional credits.
With our 5,000-credit pack ($99.90), a 5-second video costs approximately $0.50 at 720p or $0.80 at 1080p. That's about $0.10–$0.16 per second. Costs vary by resolution, duration, and reference video length. You can review the estimated credit cost in the generator before starting.
View pricing and credit packsWhen you start a generation, the estimated credit cost is temporarily deducted from your balance. Credits are only charged for successful generations. If the task fails, the reserved credits are returned to your balance. If your balance doesn’t update as expected, contact support@kling-4.art with your task details.
