Kling 4.0: longer videos, keyframes, editing and a Flash draft mode
Kling 4.0 is now available for text-to-video, image-to-video, reference-to-video, keyframes and video editing, alongside a faster Flash variant for quick drafts.
- Up to 30 seconds at 720p or 1080p (Flash tops out at 20s and 720p)
- Multi-shot prompts, up to 7 reference elements and 10 keyframes in one generation
- Start and end frames for image-to-video, native audio on keyframes mode
- Video editing from a source clip guided by a text prompt
- $0.157/s at 720p, $0.235/s at 1080p (Flash is 720p only at $0.157/s)
Flash trades resolution and the end-frame, keyframes and edit modes for speed; use it for iterations, then switch to the full model for the final render.
