Kling 4.0 Test: Recreating Water-Sleeve Dance Needs 7-8 Prompt Iterations

Kling 4.0 formally launched on October 15, extending native generation to 30 seconds and shipping updates in complex motion, reference control, and video editing. On November 3, Leiphone published a hands-on test built around the complex motion upgrade, covering four tasks: recreating the water-sleeve drum dance from the film House of Flying Daggers, generating the classic solo from Singin' in the Rain, shooting a 30-second lifestyle clip of an ordinary woman walking through an old neighborhood, and editing an already generated video.

The water-sleeve dance proved the hardest of these. The dancer's bodywork, the cloth's trajectory, and the dense drum pattern all need to line up, and condensing those demands into a prompt turned out to be unforgiving. Leiphone went through seven or eight rounds of prompt revision before the output matched expectations closely, which was less seamless than the official sample footage suggests. The report does not include a final assessment of the finished clip, and no detailed results or metrics are provided for the remaining Kling 4.0 tests.
