Direct a whole scene in one generation
Length
30-second takes
Pick any length from 3 to 30 seconds. A full scene comes back as one continuous clip, with no short shots to stitch together afterwards.
References
Up to 15 references at once
Combine up to 10 images and 5 video clips in a single request. Cast a character, place a product, set the location, and Kling 4.0 builds the shot around all of them.
Keyframes
Frames at the start, middle and end
Pin an opening frame, add up to eight frames in between and an optional closing frame. The scene moves through each beat in the order you set.
Editing
Rework footage you already have
Bring in a clip up to 30 seconds long and describe the change: new weather, a new setting, a different look. The edit keeps the original's length and framing.
