Kling 3 Pro vs Runway Gen-4.5
Kling 3 Pro edges out Gen-4.5 overall (Kling 3 Pro 62.0 vs Gen-4.5 40.0.) Kling 3 Pro is a clear upgrade from Kling 2.6 and the Veo 3.1 models on most dimensions. It excels at human performance and emotive acting, has some of the best prompt understanding of any model, and produces cinematic, well-composed shots with standout animal realism. It can very fluidly go from slow motion to regular speed, showing really good temporal coherence. It can generate some nonsensical outputs, so expect to run a few prompts to get it right. But when it gets it right, it's quite good. 2D animation and anime are average. Text rendering is just okay and may require some re-prompting. The main tradeoffs are in Expensive, Can generate nonsensical outputs, where Gen-4.5 tends to score better.

Prompt
Anime walking-shot in the style of a quiet contemporary anime film, low POV camera tracking forward over a dirt road, framing a person's worn sneakers and beige cargo pants stepping in steady rhythm. Ahead, a small valley town spills downhill under a blazing orange sunset streaked with telephone lines and clouds. Painterly clouds with rim-lit edges, hand-drawn dust puffs at each step, the kind of contemplative end-of-day walk that doesn't need narration.

Wide tracking shot of a small white research boat motoring across glassy fjord water as a colossal moss-covered crustacean kaiju rises from beneath the surface, its barnacle-encrusted claws sweeping arcs of seawater into the air.
