Kling 4.0
Long takes and 4K HDR, made for the edit.
What it is
Kling 4.0 launched in October 2026 with a clear target: footage that survives post-production. It generates up to 30 seconds in a single pass, extends a sequence to two minutes, and outputs 4K or 1080p 10-bit HDR in aspect ratios up to 21:9.
Control is the point. Up to ten keyframes set the beats, Omni Reference combines ten images, five videos and seven subjects, and prompts of up to 8,000 tokens can carry full screen direction. Subjects, backgrounds, style, weather and lighting can be edited after generation.
Profiles describe the model, not a guarantee: the Skill folder is what makes the work repeatable, and the agent's settings decide what the model can reach.
What it's best at
The work this engine is built for, and where it earns its place in a run.
Long, stable takes
Thirty-second single-pass generation built for action and complex camera moves.
Keyframe control
Up to ten keyframes pin character state, scene changes and plot beats.
Omni Reference
Ten images, five videos and seven subjects can drive one task.
Editing and lip sync
Add, remove or restyle subjects and backgrounds; improve lip sync and stereo audio.
A good first run
Three video Skills to try on Kling 4.0 — each one a folder of instructions the model can pick up straight away.
