Cinematic motion

Kling 3.0 is known for realistic human motion, physically plausible action and film-like camera work. It follows complex, multi-step prompts closely and keeps faces and hands stable across the shot.

Native audio

Turn on audio to get synchronized dialogue, ambience and effects generated with the picture — no separate sound pass.

What it's good at

  • Character-driven scenes and short-drama shots
  • Product and fashion videos from a single image
  • First-to-last-frame transitions
  • Any length from 3 to 15 seconds

Kling 3.0 FAQ
