Kling
Kling 3.0 is the upstream pick when the source clip features human performers — its human motion engine produces the most anatomically accurate body, face, and clothing motion of any video generator on Martini, which means the upscaler has clean motion to work with rather than soft AI-motion artifacts. The pipeline is identical to Seedance: generate the source on Kling 3.0, then route through the configured video upscaler tool node for the 4K master. Default 2x is the safe choice (1080p → 4K equivalent); 4x for hero shots only. The companion `tools/video-upscale` page covers upscaler parameters; this how-to focuses on the Kling-paired pipeline specifically.
Kling 3.0's comparative advantage is human motion — a person walking, running, dancing, gesturing, or speaking will look more anatomically correct on Kling than on Seedance, Sora, or Runway Gen-4 at equivalent settings. Pick Kling 3.0 specifically when the source clip features a human (or humanoid character) as the focal subject. Generate at Kling's native quality settings — like Seedance, don't push native 4K output. The upscaler in the next step takes a clean 1080p Kling output to 4K cleanly; pushing native 4K from the generator produces noisier, less polished motion.
Add a Tool node, select the workspace's configured video upscaler, and connect Kling 3.0's Video output. The upscaler runs as an async FAL queue job. For Kling-sourced clips specifically, the upscaler tends to handle face detail and skin tone gradients well — Kling's clean human rendering gives the upscaler good signal to enhance rather than artifact-laden source frames. Render time scales with clip length and upscale factor: budget 8-20 minutes for a 5-second clip at 2x (slightly longer than Seedance because Kling outputs tend to have more motion data per frame).
2x is the standard pick — 1080p × 2x = 4K equivalent for YouTube, broadcast, and high-end social. For talent-focused hero shots (a presenter's close-up, a dancer's feature, a product spokesperson's primary frame), the 4x option becomes worth the extra render and credit cost: skin texture, hair detail, and fabric weave gain visible refinement that audiences register subconsciously. For everything else — establishing shots, ensemble work, B-roll — 2x is the right choice. Don't stack 2x → 2x to reach 4x effective; the artifact compounding rarely beats a single 4x pass.
For talking-head content, the typical Kling-anchored pipeline is: generate body/scene with Kling 3.0 → animate dialogue with Kling Lipsync or OmniHuman (audio-driven mouth movement on a portrait) → composite onto the body shot → upscale the final composite to 4K. Doing the upscale at the end (rather than upscaling each component separately and re-compositing) preserves edge alignment between the lipsynced face and the body. Kling 3.0 + OmniHuman + 2x upscale is the standard pipeline for branded marketing videos, executive presentations, and high-stakes social content where talent-on-screen needs broadcast-level finish.
Kling 3.0 is the right pick when the source clip features human or humanoid performers. For non-human content (products, environments, abstract motion), Seedance 2.0 is usually the cleaner choice.
2x default for everything; 4x for talent-focused hero shots where skin texture and hair detail register to the audience. Don't stack 2x → 2x.
Talking-head pipelines benefit from upscaling the final composite (Kling 3.0 + OmniHuman) rather than each component separately — preserves edge alignment between lipsynced face and body.
Render time for Kling-sourced clips runs slightly longer than Seedance through the upscaler because Kling outputs carry more motion data per frame. Budget 8-20 minutes for 5s at 2x.
Companion tool page: `models/tools/video-upscale` covers upscaler routing and parameters in detail. This how-to is the Kling-paired pipeline specifically.
Kling 3.0 → video upscale is the talent-focused 4K master pipeline on Martini. The human motion engine gives the upscaler the cleanest signal possible for skin, hair, fabric, and gesture; the upscaler's job becomes detail enhancement rather than artifact correction. Trade-off vs. Seedance 2.0 paired: Kling is the right pick for any clip with people; Seedance is the cleaner choice for products, environments, and modern lifestyle content. For talking-head pipelines, the standard architecture is Kling 3.0 source → OmniHuman or Kling Lipsync overlay → composite → 2x upscale → NLE export. Everything stays on the Martini canvas so the editor can iterate without leaving the workspace.
