Kling 4

Kling 4 on EchoClip — daily-driver motion, sharper detail, strong i2v, and storyboard FLF beats.

Kling 4 is what most teams open first: quick text-to-video for hooks, reliable image-to-video from thumbnails, and first-last-frame generation when Director or MCP storyboards give you start/end keyframes for a beat.

When to use it

  • Social hooks and UGC-style motion you will iterate many times
  • Animating a thumbnail or storyboard frame from Image studio
  • First-last-frame clips between two approved stills (MCP storyboard workflows)

Reach for something else when

  • You need maximum photorealism for a single hero TV spot — compare Veo for the final
  • Audio-driven performance is the focus — pair with Voice + Lip Sync instead
