KuaishouKling 4.0
Kling's newest model: clips up to 30 seconds with sound, steered by your own images and videos.
What is Kling 4.0?
Kling 4.0 is Kuaishou's newest video model, built to follow reference images and videos closely over long clips.
On Nsketch it renders 3 to 30 seconds at 720p or 1080p, with audio generated alongside the video. You can give it up to 10 reference images and up to 5 reference videos in one generation.
Pick it when the look has to come from your own material: a character from a few photos, a camera move from a clip you like, a product from its catalog shots. It doesn't take first and last frames or audio references; for those, Seedance 2.5 or Wan 3.0 fit better.
