Kling 4.0 hands-on tests and comparisons

A user shares a full four-panel horror prompt (rainy alley, droplet reflection, face close-up, long street with a second shadow) tested on Kling 4.0 for multi-panel consistency.

A Kling 4.0 test notes foot sliding in the character's walk but no major visual breakdown, alongside a MiniMax H3 cat-and-fishmonger prompt comparison.

A user tested Kling 4.0, using first, middle and end frames to generate a 30-second 720p video in one pass for 300 credits (270 with the current discount), and rates it positively.

Pollo AI generated a flying-car chase with Kling 4.0, then used Pollo Recast to swap in a night city view and asked viewers which they prefer.

A user compared Kling 3.0 and 4.0 with the same prompt, noting 9-language stereo audio including French, clips doubled to 30 seconds, steadier lip sync, up to 10 keyframes and 15 references, and MCP/CLI access.

A Japanese user tests Kling 4.0 generating a 10-second clip from five input images, a clear upgrade over 3.0's two-frame start/end control.

The post says Kling 4.0 generates 30-second 4K clips with 10 keyframes and synced audio in one pass, which the author hopes will remove the need to stitch many shots.

A user tests Kling 4.0's live-action lip sync and says the accuracy is so high they can't tell it apart from Seedance 2.5.

A Japanese user says Kling 4.0 outputs usable videos on the first try with impressive texture, at far lower cost than Seedance 2.5.

A shared Kling 4.0 full-model prompt and start image for a 15-second 720p 16:9 car chase with native sound, split into timed beats covering camera moves, vehicle consistency and gunfire pacing.

Comparing the same prompt, the author finds Seedance 2.5 performs a genuine camera pull-back from eye to full face with stable space, while Kling 4.0 mid-clip looks like the eye dissolves into a face, and Seedance's dust and droplets drift more naturally.

A creator runs the same prompt and reference image through Kling 4.0 and Seedance 2.5 and posts a side-by-side video asking viewers which they prefer.
