Enhanced 1080p image motion conversion for expressive, fluid video creation
Kling V3.0 4K is the native 4K tier of the Kling V3.0 multimodal AI video generation model on RunComfy. It turns text prompts into ultra-high-resolution cinematic clips at 3840×2160, with the same multi-shot sequencing, synchronized audio, and professional camera control as the rest of the V3.0 family — purpose-built for master-quality deliverables that don’t need post-production upscaling.

Kling V3.0 4K is the native 4K tier of the Kling V3.0 family. Unlike the Standard and Pro variants, it renders directly at 3840×2160 in a single pass — no upscaling step — so fine textures, edges, and motion detail hold up under close inspection and large-format display. It shares the same multi-shot architecture, synchronized audio, and parameter set as the rest of the family, so you get master-quality resolution without changing how you prompt.
Yes. Kling V3.0 4K outputs natively at 3840×2160 (UHD 4K) regardless of the chosen aspect ratio. There is no post-process upscale in the pipeline, which means details like skin pores, fabric weaves, and lens highlights are generated at full 4K resolution rather than reconstructed from a lower-resolution base.
Most competing text-to-video models, including Seedance 1.0 Pro and Wan 2.5, target 1080p as their native ceiling and rely on upscaling for higher resolutions. Kling V3.0 4K outputs native 4K directly, with stronger temporal coherence across multi-shot sequences and tighter audio-video sync. Competitors may still excel in specific stylized renderings, but for native-resolution master deliverables Kling V3.0 4K has a clear advantage.
Kling V3.0 4K outputs are limited to around 15 seconds per generation, with up to six continuous shots. Native resolution is 3840×2160, and aspect ratios typically include 16:9, 9:16, and 1:1. Prompts usually support up to 1,200 tokens, and reference inputs are limited to a small number per generation depending on node configuration. Because of the high resolution, expect longer generation latency than the Standard or Pro variants.
Yes. Kling V3.0 4K supports chaining up to six shots into one coherent 4K clip using the same multi-shot feature as the rest of the V3.0 family. Developers can define shot types, camera angles, and transitions directly in prompts or via multi_prompt in the RunComfy Playground. The system maintains consistent lighting and character continuity across shots at full 4K resolution.
Once you’ve validated your Kling V3.0 4K text-to-video workflows in the RunComfy Playground, you can move to production via the RunComfy API. The API mirrors all playground settings — including shot definitions, multi-prompt segments, and audio toggle — but operates via authenticated REST endpoints. You’ll need to generate an API key, allocate production usd credits, and handle asynchronous video retrieval through RunComfy’s job queue structure.
Yes. Kling V3.0 4K includes the same integrated audio synthesis and dynamic lip-sync capabilities as the rest of the V3.0 family, supporting English, Chinese, Japanese, Korean, and Spanish. When generating clips with dialogue descriptions, it automatically synchronizes the generated speech and mouth motions in a single 4K generation pass — no separate dubbing step is needed.
Kling V3.0 4K lets users specify professional camera semantics (panning, dolly, tilt, POV) and motion descriptions directly in text prompts. At native 4K, optical details like parallax depth, lens highlights, and compositional balance render with notably more clarity than 1080p variants, giving Technical Artists more usable cinematic control for finished masters.
Kling V3.0 4K is billed at a flat $0.42 per second whether or not audio is enabled, which makes budgeting predictable for 4K projects. By comparison, the Standard variant runs at $0.084 per second without audio and $0.126 per second with audio, and the Pro variant runs at $0.112 per second without audio and $0.168 per second with audio. The 4K rate reflects the higher per-frame compute required to render natively at 3840×2160.
Commercial usage of Kling V3.0 4K text-to-video outputs depends on Kuaishou Technology’s published license terms and RunComfy’s service agreement. Generally, the generated videos are usable for marketing or creative projects, but you should verify any commercial-use clauses or attribution requirements from the official license pages before deployment.
For standard users through RunComfy Playground, all rendering happens cloud-side, so no local 4K-capable GPU is needed. However, if integrating Kling V3.0 4K via API, expect noticeably longer latency than the Standard or Pro variants because of the much higher per-frame pixel count. Efficient prompt design, moderate clip duration, and reusing prompt templates can help reduce both generation time and cost.
