What Kling 4.0 generates

30-second single takes

One generation runs up to 30 seconds, so a tracking shot, a product reveal, or a full ad beat plays out without a stitch.

Story control with 10 keyframes

Upload the frames your clip has to hit, from the opening image to the final beat, and Kling 4.0 fills in the motion between them.

Consistency from 15 references

Mix up to 10 images, 5 video clips, saved elements, and voice samples to hold a face, a product, a move, and a voice steady.

Kling 4.0 Flash for volume

Flash turns out 3 to 20 second clips at 720p, quick enough to test a dozen hooks or formats before one goes to a full render.
