Why Choose Kling 4.0?
Longer takes and deeper control in one video model.
- Native 30-Second Takes
- Generate 3 to 30 seconds in a single creation. The longer timeline gives a scene room for an opening, development, action, and a clear ending without stitching several clips together.
- Start and End Frames
- Pin how a scene begins and where it ends. Kling 4.0 generates the motion between your first and last image.
- Up to 10 Reference Images
- Pass in characters, products, and environments as reference images and call them from the prompt as @Image1, @Image2, and so on, so they stay recognizable across a scene.
- 720p and 1080p
- Pick 720p for fast drafts or 1080p for finished clips, with 16:9, 9:16, 1:1, and 21:9 aspect ratios on text-to-video.
- Edit Existing Footage
- Upload a clip of 3 to 30 seconds and describe the change, such as a new background or a different style. Add reference images to guide how the result should look.
