What Kling 4.0 adds
Kling 4.0 is available in Create. Select its supported settings and review the exact credit quote before generation.
Kling 4.0
According to Kuaishou's Kling 4.0 user guide, a single generation can run for 3–30 seconds, with up to 10 keyframes in the keyframe mode. Its separate Omni Reference mode accepts up to 15 mixed assets, subject to the guide's limits for each asset type. The guide also describes built-in stereo audio. These are Kuaishou platform capabilities, not FilmLune controls.
Text, a starting image, timed frames and references serve different purposes. Use a keyframe to mark a visual state at a point in the clip; use a reference to describe appearance, movement or sound. A 30-second generation is still one bounded clip, not an editing timeline or a promise of future extension on FilmLune.
