Kling 4.0 hands-on tests and comparisons

A user reran several previously used Japanese prompts on Kling 4.0 and found the outputs disappointing, unsure whether the prompts or the model are to blame.

After Kling 4.0's official launch with MCP support, the author lays out the order of steps to follow in your first 30 minutes of wiring it into Claude Code.

A Japanese user says Kling 4.0's improvement over 3.0 is hard to notice in low-motion scenes, and regrets choosing 20 seconds instead of 30 due to cost.

A promotional post lists Kling 4.0's public rollout features: 30-second video generation, reference support, smoother action and more precise scene control, without hands-on detail.

Relaying the rollout news: Kling 4.0 is available to everyone with up to 30-second generations, cinematic camera work and advanced reference support.

A same-prompt comparison of Kling 4.0 and Seedance 2.5 across four 10s themes found no clear winner: Kling is cheaper and more photoreal, but its watercolor fox turns into real fur while Seedance keeps the watercolor strokes.

A user says Kling 4.0 is fully available to everyone and demos complex scenes with smooth camera transitions, without specific specs.

Kling 4.0 is officially live with native 30-second generation and 10-bit HDR at 4K/1080p/21:9, with the poster arguing competition has shifted to stable, controllable delivery.

A hands-on report finding Kling 4.0 holds motion stability during complex movement, native 30s generation reduces stitching, and Omni Reference helps consistency.

User notes Kling 4.0's dynamic motion progress: stable tracking, seated figures holding, and an origami bird crossing without melting, making multi-subject long takes usable.

With the same skill, prompt and Kling 4.0 model, the author finds Claude Code produces more tasteful videos and captures subtle nuances better.

Pandaily reports Kling 4.0 is now open to all users, adding dual-channel audio, multi-language lip sync and MCP/CLI access, with 4K HDR and an enterprise API coming soon.
