Kling 4.0 stretches videos to 30 seconds and accepts ten keyframes
The new version of the video generator focuses on storytelling: longer shots and control through successive keyframes.
On October 15, Kling unveiled version 4.0 of its video generation model. Two numbers sum up the announcement: clips of up to 30 seconds, and the ability to supply up to 10 keyframes to guide the sequence.
Why keyframes matter
Many video generators work from a text prompt and, at best, a start frame and an end frame. The result is often spectacular but hard to direct. With ten keyframes, users can pin down intermediate steps: a character entering, a change of scenery, the final framing. It gets closer to a storyboard that the model then animates.
The 30-second length points the same way. A shot of a few seconds is enough for an effect; thirty seconds allow for a short scene, a product demo or a complete narrative transition.
The developer’s announcement stresses three themes: visual realism, creative control and storytelling. The first two are a matter of judgment and have not yet been the subject of published independent measurements.
Our take
The race is no longer just about how beautiful the image looks, but about the ability to tell a sequence the way you intended. Advertising and music-video professionals should first test how well characters hold up over 30 seconds: that is where video models fail most often.
