Generate up to 30 seconds in a single pass—twice the maximum length of Kling 3.0. Give dialogue, action and camera movement more time to develop, with fewer separate clips to stitch into a coherent scene.
Create videos in up to 4K, with 10-bit HDR at 1080p and 4K for richer colors, smoother gradients and more detail in highlights and shadows. A 21:9 ultrawide format gives landscapes, action scenes and product shots more room in the frame.
Use up to 10 keyframes to guide character poses, scene transitions and story beats. Combine up to 15 references, including images, videos and subjects, to define appearance, movement, camera work and pacing without explaining every detail in text.
Bring voices, sound effects and ambience into the same generation with native dual-channel stereo audio. Improved lip sync and support for nine languages, plus regional accents and dialects, help character conversations feel more natural across different audiences.
Adjust expressions, movements, camera angles, backgrounds or visual styles while keeping the rest of the scene stable. Use a reference video to guide pacing and shot composition, then introduce your own characters or products to develop a new version of the idea.
